Manage permissions for recipients – Support Latam

In Exchange Server 2016, you can use the Exchange admin center (EAC) or the Exchange Management Shell to assign permissions to a mailbox or group so that other users can access the mailbox (the Full Access permission), or send email messages that appear to come from the mailbox or group (the Send As or Send on Behalf permissions). The users that are assigned these permissions on other mailboxes or groups are called delegates.

The permissions that you can assign to delegates for mailboxes and groups in Exchange 2016 are described in the following table*:

Permission Description Available on objects in the EAC Available on addtional objects in the Exchange Management Shell Available delegate types in the EAC Additional delegate types available in the Exchange Management Shell

Full Access

Allows the delegate to open the mailbox, and view, add and remove the contents of the mailbox. Doesn't allow the delegate to send messages from the mailbox.

If you assign this permission to a mailbox that's hidden from address lists, the delegate won't be able to open the mailbox. By default, arbitration and discovery mailboxes are hidden from address lists.

By default, the mailbox auto-mapping feature uses Autodiscover to automatically open the mailbox in the delegate's Outlook profile (in addition to their own mailbox). If you don't want this to happen, you need to take one of the following actions:

Use the Add-MailboxPermission cmdlet in the Exchange Management Shell to assign the Full Access permission with the -AutoMapping $false setting. For more information, see the Use the Exchange Management Shell to assign the Full Access permission to mailboxes section in this topic.
Assign the Full Access permission to a (mail-enabled) security group. The mailbox won't open in the Outlook profile of each member.

Send on Behalf

Allows the delegate to send messages from the mailbox or group. The From address of these messages clearly shows that the message was sent by the delegate ("<Delegate> on behalf of <MailboxOrGroup>"). However, replies to these messages are sent to the mailbox or group, not to the delegate.

Doesn't allow the delegate to read the contents of the mailbox.

What do you want to do?

Use the EAC to assign permissions to individual mailboxes

In the EAC, click Recipients in the feature pane. Depending on the type of mailbox that you want to assign permissions for, click on one of the following tabs:
- Mailboxes User or linked mailboxes.
- Resources Room or equipment mailboxes.
- Shared Shared mailboxes.
In the list of mailboxes, select the mailbox that you want to assign permissions for, and then click Edit .
On the mailbox properties page that opens, click Mailbox delegation and configure one or more of the following permissions:
- Send As Messages sent by a delegate appear to come from the mailbox.
- Send on Behalf Messages sent by a delegate have "<Delegate> on behalf of <Mailbox>" in the From address. Note that this permission isn't available in the EAC for shared mailboxes.
- Full Access The delegate can open the mailbox and do anything except send messages.
To assign permissions to delegates, click Add under the appropriate permission. A dialog box appears that lists the users or groups that can have the permission assigned to them. Select the user or group from the list, and then click Add. Repeat this process as many times as necessary. You can also search for users or groups in the search box by typing all or part of the name, and then clicking Search . When you are finished selecting delegates, click OK.

To remove a permission from a delegate, select the delegate in the list under the appropriate permission, and then click Remove .
When you are finished, click Save.

Use the EAC to assign permissions to multiple mailboxes at the same time

In the EAC, navigate to Recipients > Mailboxes.
Select the mailboxes that you want to assign permissions for. Use click + Shift key + click to select a range of mailboxes, or Ctrl key + click to select multiple individual mailboxes. The title of the details pane changes to Bulk Edit as shown in the following diagram.

Note that the mailboxes that you select need to be the same type. For example, if you select both user mailboxes and linked mailboxes, you'll get a warning in the details pane that says bulk edit won't work.
At the bottom of the details pane, click More options. Under the Mailbox Delegation option that appears, choose Add or Remove. Depending on your selection, do one of the following steps:
- Add In the Bulk Add Delegation dialog box that appears, click Add under the appropriate permission (Send As, Send on Behalf, or Full Access). When you are finished selecting users or groups to add as delegates, click Save.
- Remove In the Bulk Remove Delegation dialog box that appears, click Add under the appropriate permission (Send As, Send on Behalf, or Full Access). When you are finished selecting users or groups to remove from the existing delegates, click Save.

Use the EAC to assign permissions to groups

In the EAC, navigate to Recipients > Groups.
In the list of groups, select the group that you want to assign permissions for, and then click Edit .
On the group properties page that opens, click Group delegation and configure one of the following permissions:
- Send As Messages sent by a delegate appear to come from the group.
- Send on Behalf Messages sent by a delegate have "<Delegate> on behalf of <Group>" in the From address.
To assign permissions to delegates, click Add under the appropriate permission. A dialog box appears that lists the users or groups that can have the permission assigned to them. Select the user or group from the list, and then click Add. Repeat this process as many times as necessary. You can also search for users or groups in the search box by typing all or part of the name, and then clicking Search . When you are finished selecting delegates, click OK.

To remove a permission from a delegate, select the delegate in the list under the appropriate permission, and then click Remove .
When you are finished, click Save.

Use the Exchange Management Shell to assign the Full Access permission to mailboxes

You use the Add-MailboxPermission and Remove-MailboxPermission cmdlets to manage the Full Access permission for mailboxes. These cmdlets use the same basic syntax:

Copy

Add-MailboxPermission -Identity <MailboxIdentity> -User <DelegateIdentity> -AccessRights FullAccess -InheritanceType All [-AutoMapping $false]

For more information, see Add-MailboxPermission.

Copy

Remove-MailboxPermission -Identity <MailboxIdentity> -User <DelegateIdentity> -AccessRights FullAccess -InheritanceType All

For more information, see Remove-MailboxPermission.

This example assigns the delegate Raymond Sam the Full Access permission to the mailbox of Terry Adams.

Copy

Add-MailboxPermission -Identity "Terry Adams" -User raymonds -AccessRights FullAccess -InheritanceType All

This example assigns Esther Valle the Full Access permission to the organization's default discovery search mailbox, and prevents the mailbox from automatically opening in Esther Valle's Outlook.

Copy

Add-MailboxPermission -Identity "DiscoverySearchMailbox{D919BA05-46A6-415f-80AD-7E09334BB852}" -User estherv -AccessRights FullAccess -InheritanceType All -AutoMapping $false

This example assigns members of the Helpdesk mail-enabled security group the Full Access permission to the shared mailbox named Helpdesk Tickets.

Copy

Add-MailboxPermission -Identity "Helpdesk Tickets" -User Helpdesk -AccessRights FullAccess -InheritanceType All

This example removes Full Access permission for Jim Hance from Ayla Kol's mailbox.

Copy

Remove-MailboxPermission -Identity ayla -User "Jim Hance" -AccessRights FullAccess -InheritanceType All

Note: If you've already assigned the Full Access permission to a delegate in the EAC or without using the -AutoMapping $false setting on

How do you know this worked?

To verify that you've assigned or removed the Full Access permission for a delegate on a mailbox, use either of the following procedures:

In the properties of the mailbox in the EAC, verify the delegate is or isn't listed in Mailbox delegation > Full Access.
Run the following command in the Exchange Management Shell to verify the delegate is or isn't listed. Be sure to replace <MailboxIdentity> with the identity of the mailbox.
Copy
Get-MailboxPermission <MailboxIdentity> | where {$_.AccessRights -like 'Full*'} | Format-Table -Auto User,Deny,IsInherited,AccessRights
For more information, see Get-MailboxPermission.

Use the Exchange Management Shell to assign the Send As permission to mailboxes and groups

You use the Add-AdPermission and Remove-AdPermission cmdlets to manage Send As permission for mailboxes. These cmdlets use the same basic syntax:

Copy

<Add-AdPermission | Remove-AdPermission> -Identity <MailboxOrGroupNameOrDN> -User <DelegateIdentity> [-AccessRights ExtendedRight] -ExtendedRights "Send As"

For more information, see Add-ADPermission and Remove-ADPermission.

Notes:

The Identity parameter requires you to use the Name or DistinguishedName (DN) value of the mailbox or group.
- Name This value may or may not be the same as the display name. For example, Felipe Apodaca.
- DistinguishedName This value always contains the Name value and uses Active Directory LDAP syntax. For example, CN=Felipe Apodaca,CN=Users,DC=contoso,DC=com.
To find these values for a mailbox or group, you can use the Get-Recipient cmdlet, which accepts many different values for the Identity parameter. For example:
Copy
Get-Recipient -Identity helpdesk@contoso.com | Format-List Name,DistinguishedName
The commands work with or without -AccessRights ExtendedRight, which is why it's shown as optional in the syntax.

This example assigns the Send As permission to the Helpdesk mail-enabled security group on the shared mailbox named Helpdesk Support Team.

Copy

Add-ADPermission -Identity "Helpdesk Support Team" -User Helpdesk -ExtendedRights "Send As"

This example removes the Send As permission for the user Pilar Pinilla on the mailbox of James Alvord.

Copy

Remove-ADPermission -Identity "James Alvord" -User pilarp -ExtendedRights "Send As"

How do you know this worked?

To verify that you've assigned or removed the Send As permission for a delegate on a mailbox or group, use either of the following procedures:

In the properties of the mailbox or group in the EAC, verify the delegate is or isn't listed in Mailbox delegation > Send As or Group delegation > Send As.
Run the following command in the Exchange Management Shell to verify the delegate is or isn't listed. Be sure to replace <MailboxOrGroupNameOrDN> with the name or distinguished name of the mailbox or group.
Copy
Get-ADPermission -Identity <MailboxOrGroupNameOrDN> | where {$_.ExtendedRights -like 'Send*'} | Format-Table -Auto User,Deny,ExtendedRights
For more information, see Get-ADPermission.

Use the Exchange Management Shell to assign the Send on Behalf permission to mailboxes and groups

You use the Set- cmdlets for the various mailbox and group cmdlets to manage Send on Behalf permission for mailboxes and groups:

Set-Mailbox
Set-DistributionGroup Distribution groups and mail-enabled security groups.
Set-DynamicDistributionGroup

The basic syntax for these cmdlets is:

Copy

<Cmdlet> -Identity <MailboxOrGroupIdentity> -GrantSendOnBehalfTo <DelegateIdentity>

<DelegateIdentity> can be one of the following values:

To replace any existing delegates with the values you specify, use the syntax <DelegateIdentity1>,<DelegateIdentity2>.... If the delegate identity value contains spaces, you need to use quotation marks: "<DelegateIdentity1>","<DelegateIdentity2>"....
To add new delegates without affecting other existing entries, use the syntax @{Add="<DelegateIdentity1>","<DelegateIdentity2>"...}.
To remove existing delegates without affecting other delegates, use the syntax @{Remove="<DelegateIdentity1>","<DelegateIdentity2>"...}.
To erase all existing delegates, use the value $null.

This example assigns the delegate Holly Holt the Send on Behalf permission to the mailbox of Sean Chai.

Copy

Set-Mailbox -Identity seanc@contoso.com -GrantSendOnBehalfTo hollyh

This example adds the group named Temporary Executives to the list of delegates that have Send on Behalf permission to the Contoso Executives shared mailbox.

Copy

Set-Mailbox "Contoso Executives" -GrantSendOnBehalfTo @{Add="tempassistants@contoso.com"}

This example assigns the delegate Sara Davis the Send on Behalf permission to the Printer Support distribution group.

Copy

Set-DistributionGroup -Identity printersupport@contoso.com -GrantSendOnBehalfTo sarad

This example removes the Send on Behalf permission that was assigned to the administrator on the All Employees dynamic distribution group.

Copy

Set-DynamicDistributionGroup "All Employees" -GrantSendOnBehalfTo @{Remove="Administrator"}

How do you know this worked?

To verify that you've assigned or removed the Send on Behalf permission for a delegate on a mailbox or group, use either of the following procedures:

In the properties of the mailbox or group in the EAC, verify the delegate is or isn't listed in Mailbox delegation > Send As or Group delegation > Send As.
Run the one of the following commands in the Exchange Management Shell to verify the delegate is or isn't listed. Be sure to replace <MailboxIdentity> or <GroupIdentity> with the identity of the mailbox or group.
- Mailbox:
  Copy
  Get-Mailbox -Identity <MailboxIdentity> | Format-List GrantSendOnBehalfTo
- Group:
  Copy
  Get-DistributionGroup -Identity <GroupIdentity> | Format-List GrantSendOnBehalfTo
- Dynamic distribution group:
  Copy
  Get-DynamicDistributionGroup -Identity <GroupIdentity> | Format-List GrantSendOnBehalfTo
