A valid value is a number up to 1.999999 gigabytes (2147483647 bytes) or the value unlimited. In Office 365, the value is determined by the subscriptions and licenses that administrators purchase and assign in the Office 365 admin center. You can lower the value, and you may be able to raise the value, but you can't exceed the maximum value that's allowed by the subscription or license. In Office 365, you use this parameter to configure the MaxSendSize value on existing mailboxes. Use the Set-MailboxPlan cmdlet to change the MaxSendSize value for all new mailboxes that you create in the future. In on-premises Exchange, the default value unlimited indicates the maximum send size for the mailbox is controlled elsewhere (for example, organization, server, or connector limits). For any message size limit, you need to set a value that's larger than the actual size you want enforced. This accounts for the Base64 encoding of attachments and other binary data. Base64 encoding increases the size of the message by approximately 33%, so the value you specify should be approximately 33% larger than the actual message size you want enforced. For example, if you specify a maximum message size value of 64 MB, you can expect a realistic maximum message size of approximately 48 MB.	Field Name: MaxSendSize Type: String

For example: Name Display name Alias Distinguished name (DN) Canonical DN Email address GUID You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: <sender1>,<senter2>.... If the values contain spaces or otherwise require quotation marks, use the following syntax: "<sender1>","<sender2>".... To add or remove senders without affecting other existing entries, use the following syntax: @{Add="<sender1>","<sender2>"...; Remove="<sender1>","<sender2>"...}. The senders you specify for this parameter are automatically copied to the AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromSendersOrMembers parameters in the same command.

For more information about assignment policies, see Understanding management role assignment policies.	Field Name: RoleAssignmentPolicy Type: String
ImListMigrationCompleted				The ImListMigrationCompleted parameter specifies whether a user's Lync or Skype for Business contact list is stored in their mailbox. Valid values are: $true The user's Lync or Skype for Business contact list is stored in their Exchange 2016 mailbox. This prevents you from migrating the mailbox back to an Exchange 2010 server. $false The user's Lync or Skype for Business contact list is stored on a Lync or Skype for Business server. This doesn't prevent you from migrating the mailbox back to an Exchange 2010 server. This is the default value. Lync Server 2013 and Skype for Business Server 2015 support storing the user's contact list in their Exchange 2016 mailbox. This feature is known as the unified contact store (UCS), and it allows applications to show a consistent, up-to-date contact list. However, Exchange 2010 doesn't support the unified contact store. Therefore, before you migrate a user's Exchange 2016 mailbox back to Exchange 2010, you need to move the user's Lync or Skype for Business contact list from the unified contact store back to a Lync 2013 or Skype for Business server. For more information, see Configuring Microsoft Lync Server 2013 to use the unified contact store (http://go.microsoft.com/fwlink/p/?LinkID=313550). If you migrate an Exchange 2013 mailbox back to Exchange 2010 while the user's Lync or Skype for Business contact list is stored in the unified contact store, the user could permanently lose access to those contacts. After you verify the user's Lync or Skype for Business contact list has been moved back to a Lync 2013 or Skype for Business server, you should be able to complete the mailbox migration. If you need to migrate the mailbox despite the potential for data loss, you can manually set the ImListMigrationCompleted parameter to $false.	Field Name: ImListMigrationCompleted Type: Boolean
MicrosoftOnlineServicesID				This parameter is available only in the cloud-based service. The MicrosoftOnlineServicesID parameter specifies the user ID for the object. This parameter only applies to objects in the cloud-based service. It isn't available for on-premises deployments.	Field Name: MicrosoftOnlineServicesID Type: String
ForwardingAddress				The ForwardingAddress parameter specifies a forwarding address for messages that are sent to this mailbox. A valid value for this parameter is a recipient in your organization. You can use any value that uniquely identifies the recipient. For example: Name Display name Alias Distinguished name (DN) Canonical DN Email address GUID How messages are delivered and forwarded is controlled by the DeliverToMailboxAndForward parameter. DeliverToMailboxAndForward is $true Messages are delivered to this mailbox and forwarded to the specified recipient. DeliverToMailboxAndForward is $false Messages are only forwarded to the specified recipient. Messages aren't delivered to this mailbox. The default value is blank ($null), which means no forwarding recipient is configured. If you configure values for both the ForwardingAddress and ForwardingSmtpAddress parameters, the value of ForwardingSmtpAddress is ignored. Messages are forwarded to the recipient specified by the ForwardingAddress parameter.	Field Name: ForwardingAddress Type: String
	BypassModerationFromSendersOrMembers			The BypassModerationFromSendersOrMembers parameter specifies who is allowed to send messages to this moderated recipient without approval from a moderator. Valid values for this parameter are individual senders and groups in your organization. Specifying a group means all members of the group are allowed to send messages to this recipient without approval from a moderator. To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example: Name Display name Alias Distinguished name (DN) Canonical DN Email address GUID To enter multiple senders and overwrite any existing entries, use the following syntax: <sender1>,<sender2>.... If the values contain spaces or otherwise require quotation marks, use the following syntax: "<sender1>","<sender2>".... To add or remove one or more senders without affecting any existing entries, use the following syntax: @{Add="<sender1>","<sender2>"...; Remove="<sender3>","<sender4>"...}. This parameter is meaningful only when moderation is enabled for the recipient. By default, this parameter is blank ($null), which means messages from all senders other than the designated moderators are moderated. When a moderator sends a message to this recipient, the message is isn't moderated. In other words, you don't need to use this parameter to include the moderators.	Field Name: BypassModerationFromSendersOrMembers.[n] Type: Array
MailboxRegionLastUpdateTime					Field Name: MailboxRegionLastUpdateTime Type: String
ExchangeUserAccountControl					Field Name: ExchangeUserAccountControl Type: String
MaxReceiveSize				This parameter is available only in on-premises Exchange 2016. The MaxReceiveSize parameter specifies the maximum size of a message that can be sent to the mailbox. Messages larger than the maximum size are rejected. When you enter a value, qualify the value with one of the following units: B (bytes) KB (kilobytes) MB (megabytes) GB (gigabytes) TB (terabytes) Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte. A valid value is a number up to 1.999999 gigabytes (2147483647 bytes) or the value unlimited. In Office 365, the value is determined by the subscriptions and licenses that administrators purchase and assign in the Office 365 admin center. You can lower the value, and you may be able to raise the value, but you can't exceed the maximum value that's allowed by the subscription or license. In Office 365, you use this parameter to configure the MaxReceiveSize value on existing mailboxes. Use the Set-MailboxPlan cmdlet to change the MaxReceiveSize value for all new mailboxes that you create in the future. In on-premises Exchange, the default value unlimited indicates the maximum receive size for the mailbox is controlled elsewhere (for example, organization, server, or connector limits). For any message size limit, you need to set a value that's larger than the actual size you want enforced. This accounts for the Base64 encoding of attachments and other binary data. Base64 encoding increases the size of the message by approximately 33%, so the value you specify should be approximately 33% larger than the actual message size you want enforced. For example, if you specify a maximum message size value of 64 MB, you can expect a realistic maximum message size of approximately 48 MB.	Field Name: MaxReceiveSize Type: String
	AcceptMessagesOnlyFromSendersOrMembers			The AcceptMessagesOnlyFromSendersOrMembers parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected. Valid values for this parameter are individual senders and groups in your organization. Individual senders are mailboxes, mail users, and mail contacts. Groups are distribution groups, mail-enabled security groups, and dynamic distribution groups. Specifying a group means all members of the group are allowed to send messages to this recipient. To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example: Name Display name Alias Distinguished name (DN) Canonical DN Email address GUID You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: <sender1>,<senter2>.... If the values contain spaces or otherwise require quotation marks, use the following syntax: "<sender1>","<sender2>".... To add or remove individual senders or groups without affecting other existing entries, use the AcceptMessagesOnlyFrom and AcceptMessageOnlyFromDLMembers parameters. The individual senders and groups you specify for this parameter are automatically copied to the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromDLMembers properties, respectively. Therefore, you can't use the AcceptMessagesOnlyFromSendersOrMembers parameter and the AcceptMessagesOnlyFrom or AcceptMessagesOnlyFromDLMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.	Field Name: AcceptMessagesOnlyFromSendersOrMembers.[n] Type: Array
PublicFolder				This parameter is available only in on-premises Exchange 2016. The PublicFolderswitch specifies that the mailbox is a public folder mailbox.

For example: Name Canonical name Distinguished name (DN) GUID	Field Name: OrganizationalUnit Type: String
ProhibitSendReceiveQuota				The ProhibitSendReceiveQuota parameter specifies a size limit for the mailbox. If the mailbox reaches or exceeds this size, the mailbox can't send or receive new messages. Messages sent to the mailbox are returned to the sender with a descriptive error message. This value effectively determines the maximum size of the mailbox. A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units: B (bytes) KB (kilobytes) MB (megabytes) GB (gigabytes) TB (terabytes) Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte. The value must be greater than or equal to the ProhibitSendQuota or IssueWarningQuota values. In Office 365, the quota value is determined by the subscriptions and licenses that administrators purchase and assign in the Office 365 admin center. You can lower the quota value, but you can't exceed the maximum value that's allowed by the subscription or license. In Office 365, you can't use this parameter on public folder mailboxes. In on-premises Exchange, the default value of this parameter is unlimited. When the UseDatabaseQuotaDefaults parameter is set to the value $true, the value of the this parameter is ignored, and the mailbox uses the ProhibitSendReceiveQuota value on the mailbox database. To use this parameter to enforce a specific quota value for the mailbox, you need to set the UseDatabaseQuotaDefaults parameter to the value $false.	Field Name: ProhibitSendReceiveQuota Type: String
WhenChanged					Field Name: WhenChanged Type: String Format: date-time
ImmutableId				The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies a unique and immutable identifier in the form of an SMTP address for an Exchange mailbox used for federated delegation when requesting Security Assertion Markup Language (SAML) tokens. If federation is configured for this mailbox and you don't set this parameter when you create the mailbox, Exchange creates the value for the immutable ID based upon the mailbox's ExchangeGUID and the federated account namespace, for example, [email protected]. You need to set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into an off-premises mailbox and AD FS is configured to use a different attribute than ExchangeGUID for sign-on token requests. Both, Exchange and AD FS must request the same token for the same user to ensure proper functionality for a cross-premises Exchange deployment scenario.	Field Name: ImmutableId Type: String
SCLQuarantineThreshold				This parameter is available only in on-premises Exchange 2016. The SCLQuarantineThreshold parameter specifies the SCL quarantine threshold.

Valid values are: $true The mailbox uses the MailboxRetention value that's configured on the mailbox database. This is the default value. $false When the mailbox is deleted, it's retained indefinitely.	Field Name: UseDatabaseRetentionDefaults Type: Boolean
IssueWarningQuota				The IssueWarningQuota parameter specifies the warning threshold for the size of the mailbox. If the mailbox reaches or exceeds this size, the user receives a descriptive warning message. A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units: B (bytes) KB (kilobytes) MB (megabytes) GB (gigabytes) TB (terabytes) Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte. The IssueWarningQuota value must be less than or equal to the ProhibitSendReceiveQuota value. In Office 365, the quota value is determined by the subscriptions and licenses that administrators purchase and assign in the Office 365 admin center.

RoomMailboxAccountEnabled					Field Name: RoomMailboxAccountEnabled Type: String
RecipientTypeDetails				The RecipientTypeDetails parameter specifies the type of recipients returned. Recipient types are divided into recipient types and subtypes. Each recipient type contains all common properties for all subtypes. For example, the type UserMailbox represents a user account in Active Directory that has an associated mailbox. Because there are several mailbox types, each mailbox type is identified by the RecipientTypeDetails parameter. For example, a conference room mailbox has RecipientTypeDetails set to ConferenceRoomMailbox, whereas a user mailbox has RecipientTypeDetails set to UserMailbox. You can select from the following values: ArbitrationMailbox ConferenceRoomMailbox Contact DiscoveryMailbox DynamicDistributionGroup EquipmentMailbox ExternalManagedContact ExternalManagedDistributionGroup LegacyMailbox LinkedMailbox MailboxPlan MailContact MailForestContact MailNonUniversalGroup MailUniversalDistributionGroup MailUniversalSecurityGroup MailUser PublicFolder RoleGroup RoomList RoomMailbox SharedMailbox SystemAttendantMailbox SystemMailbox User UserMailbox	Field Name: RecipientTypeDetails Type: String

This doesn't prevent you from migrating the mailbox back to an Exchange 2010 server. This is the default value. Lync Server 2013 and Skype for Business Server 2015 support storing the user's contact list in their Exchange 2016 mailbox. This feature is known as the unified contact store (UCS), and it allows applications to show a consistent, up-to-date contact list. However, Exchange 2010 doesn't support the unified contact store. Therefore, before you migrate a user's Exchange 2016 mailbox back to Exchange 2010, you need to move the user's Lync or Skype for Business contact list from the unified contact store back to a Lync 2013 or Skype for Business server. For more information, see Configuring Microsoft Lync Server 2013 to use the unified contact store (http://go.microsoft.com/fwlink/p/?LinkID=313550). If you migrate an Exchange 2013 mailbox back to Exchange 2010 while the user's Lync or Skype for Business contact list is stored in the unified contact store, the user could permanently lose access to those contacts. After you verify the user's Lync or Skype for Business contact list has been moved back to a Lync 2013 or Skype for Business server, you should be able to complete the mailbox migration. If you need to migrate the mailbox despite the potential for data loss, you can manually set the ImListMigrationCompleted parameter to $false.

If the values contain spaces or otherwise require quotation marks, use the following syntax: "<sender1>","<sender2>".... To add or remove senders without affecting other existing entries, use the following syntax: @{Add="<sender1>","<sender2>"...; Remove="<sender1>","<sender2>"...}.
