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
ComplianceTagHoldApplied			Field Name: ComplianceTagHoldApplied Type: Boolean
ExternalEmailAddress *		The ExternalEmailAddress parameter specifies the target email address of the mail contact or mail user. By default, this value is used as the primary email address of the mail contact or mail user.

Valid syntax for this parameter is [<Type>]:<emailaddress1>,[<Type>]:<emailaddress2>.... The optional <Type> value specifies the type of email address. Some examples of valid values include: SMTP The primary SMTP address. You can use this value only once in a command. smtp Other SMTP email addresses. X400 X.400 addresses in on-premises Exchange. X500 X.500 addresses in on-premises Exchange. If you don't include a <Type> value for an email address, the value smtp is assumed. Note that Exchange doesn't validate the syntax of custom address types (including X.400 addresses). Therefore, you need to verify that any custom addresses are formatted correctly. To specify the primary SMTP email address, you can use any of the following methods: Use the <Type> value SMTP on the address. The first email address when you don't use any <Type> values, or when you use multiple <Type> values of smtp. If it's available, use the PrimarySmtpAddress parameter instead. You can't use the EmailAddresses parameter and the PrimarySmtpAddress parameter in the same command. To replace all existing proxy email addresses with the values you specify, use the following syntax: "[<Type>]:<emailaddress1>","[<Type>]:<emailaddress2>"....

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

	GrantSendOnBehalfTo	The GrantSendOnBehalfTo parameter specifies who can send on behalf of this mail user. Although messages sent on behalf of the mail user clearly show the sender in the From field (<Sender> on behalf of <Mail user>), replies to these messages are delivered to the mail user, not the sender. The sender you specify for this parameter must a mailbox, mail user or mail-enabled security group (a mail-enabled security principal that can have permissions assigned). You can use any value that uniquely identifies the sender. For example: Name Display name Alias Distinguished name (DN) Canonical DN <domain name>\<account name> Email address GUID LegacyExchangeDN SamAccountName User ID or user principal name (UPN) To enter multiple values and overwrite any existing entries, use the following syntax: <value1>,<value2>.... If the values contain spaces or otherwise require quotation marks, you need to use the following syntax: "<value1>","<value2>".... To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="<value1>","<value2>"...; Remove="<value1>","<value2>"...}. By default, this parameter is blank, which means no one else has permission to send on behalf of this mail user.	Field Name: GrantSendOnBehalfTo.[n] Type: Array

	RejectMessagesFromDLMembers	The RejectMessagesFromDLMembers parameter specifies who isn't allowed to send messages to this recipient. Messages from these senders are rejected. Valid values for this parameter are groups in your organization (distribution groups, mail-enabled security groups, and dynamic distribution groups). Specifying a group means all members of the group aren't allowed to send messages to this recipient. You can use any value that uniquely identifies the group. For example: Name Display name Alias Distinguished name (DN) Canonical DN Email address GUID You can enter multiple groups separated by commas. To overwrite any existing entries, use the following syntax: <group1>,<group2>.... If the values contain spaces or otherwise require quotation marks, use the following syntax: "<group1>","<group2>".... To add or remove groups without affecting other existing entries, use the following syntax: @{Add="<group1>","<group2>"...; Remove="<group1>","<group2>"...}. The groups you specify for this parameter are automatically copied to the RejectMessagesFromSendersOrMembers property. Therefore, you can't use the RejectMessagesFromDLMembers and RejectMessagesFromSendersOrMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all groups.	Field Name: RejectMessagesFromDLMembers.[n] Type: Array
IsDirSynced			Field Name: IsDirSynced Type: Boolean
ProhibitSendQuota		PARAMVALUE: Unlimited	Field Name: ProhibitSendQuota Type: String
	UMDtmfMap	The UMDtmfMap parameter specifies the dual-tone multiple-frequency (DTMF) map values for the recipient. This allows the recipient to be identified by using a telephone keypad in Unified Messaging (UM) environments. Typically, these DTMF values are automatically created and updated, but you can use this parameter to make changes manually. This parameter uses the following syntax: emailAddress:<integers> lastNameFirstName:<integers> firstNameLastName:<integers> To enter values that overwrite all existing entries, use the following syntax: emailAddress:<integers>,lastNameFirstName:<integers>,firstNameLastName:<integers>. If you use this syntax and you omit any of the DTMF map values, those values are removed from the recipient. For example, if you specify only emailAddress:<integers>, all existing lastNameFirstName and firstNameLastName values are removed. To add or remove values without affecting other existing entries, use the following syntax: @{Add="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"; Remove="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"}. If you use this syntax, you don't need to specify all of the DTMF map values, and you can specify multiple DTMF map values. For example, you can use @{Add="emailAddress:<integers1>","emailAddress:<intgers2>} to add two new values for emailAddress without affecting the existing lastNameFirstName and firstNameLastName values.	Field Name: UMDtmfMap.[n] Type: Array

Internal Moderation status notifications are sent to all internal senders, but not to external senders. Never Moderation status notifications are disabled. Note that senders are always notified if their message is rejected by a moderator, regardless of the value of this parameter.	Field Name: SendModerationNotifications Type: String
ExchangeGuid		This parameter is reserved for internal Microsoft use.	Field Name: ExchangeGuid Type: String
Alias		The Alias parameter specifies the Exchange alias (also known as the mail nickname) for the recipient. This value identifies the recipient as a mail-enabled object, and shouldn't be confused with multiple email addresses for the same recipient (also known as proxy addresses). A recipient can have only one Alias value. The value of Alias can contain letters, numbers and the characters !, #, $, %, &, ', *, +, -, /, =, ?, ^, _, `, {, \|, } and ~. Periods (.) are allowed, but each period must be surrounded by other valid characters (for example, help.desk). Unicode characters from U+00A1 to U+00FF are also allowed. The maximum length of the Alias value is 64 characters. When you create a recipient without specifying an email address, the Alias value you specify is used to generate the primary email address (<alias>@<domain>). Supported Unicode characters are mapped to best-fit US-ASCII text characters. For example, U+00F6 (ö) is changed to oe in the primary email address. If you don't use the Alias parameter when you create a recipient, the value of a different required parameter is used for the Alias property value: Recipients with user accounts (for example, user mailboxes, and mail users) The left side of the MicrosoftOnlineServicesID or UserPrincipalName parameter is used. For example, [email protected] results in the Alias property value helpdesk. Recipeints without user accounts (for example, room mailboxes, mail contacts, and distribution groups) The value of the Name parameter is used. Spaces are removed and unsupported characters are converted to question marks (?). If you modify the Alias value of an existing recipient, the primary email address is automatically updated only in on-premises environments where the recipient is subject to email address policies (the EmailAddressPolicyEnabled property is True for the recipient). The Alias parameter never generates or updates the primary email address of a mail contact or a mail user.	Field Name: Alias Type: String
RetentionComment		This parameter is reserved for internal Microsoft use.	Field Name: RetentionComment Type: String
MailTip		The MailTip parameter specifies the custom MailTip text for this recipient. The MailTip is shown to senders when they start drafting an email message to this recipient. If the value contains spaces, enclose the value in quotation marks ("). When you add a MailTip to a recipient, two things happen: HTML tags are automatically added to the text. For example, if you enter the text: "This mailbox is not monitored", the MailTip automatically becomes: <html><body>This mailbox is not monitored</body></html>. Additional HTML tags aren't supported, and the length of the MailTip can't exceed 175 displayed characters. The text is automatically added to the MailTipTranslations property of the recipient as the default value: default:<MailTip text>. If you modify the MailTip text, the default value is automatically updated in the MailTipTranslations property, and vice-versa.	Field Name: MailTip Type: String
	RejectMessagesFrom	The RejectMessagesFrom parameter specifies who isn't allowed to send messages to this recipient. Messages from these senders are rejected. Valid values for this parameter are individual senders in your organization (mailboxes, mail users, and mail contacts). 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 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 RejectMessagesFromSendersOrMembers property. Therefore, you can't use the RejectMessagesFrom and RejectMessagesFromSendersOrMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.	Field Name: RejectMessagesFrom.[n] Type: Array
