Hybrid Exchange: ‘Mailbox Delegation’ Missing?

KB ID 0001607

Problem

This was asked on EE this morning, if you are on a Hybrid Exchange environment then you cannot allocate Mailbox Delegation to an Office365 mailbox;

However you can add ‘Mailbox Delegation’ to a ‘local mailbox’.

On Premise Mailbox Delegation

This is completely normal behaviour, to allocate mailbox delegation permissions to your Office 365 mailboxes, you need to use PowerShell.

Managing Mailbox Delegation Permissions in Office 396

I’ve covered elsewhere how to do this, but first connect to Office 365;

PowerShell to Office 365

View Office 365 Mailbox Delegation Permissions

Get-MailboxPermission -Identity "Alias or email" | Format-Table

PowerShell Show Delegate Permissiona

Add Office 365 Mailbox Delegation Permissions

Add-MailboxPermission -Identity "Alias or Email of account granting rights TO" -User "Alias or Email of account granting rights FROM" -AccessRights FullAccess -InheritanceType All

PowerShell Add Delegate Permissiona O365

To check it worked simply use the Get-Mailboxpermission again;

PowerShell Check Delegate Permissions O365

Remove Office 365 Mailbox Delegation Permissions

Temove-MailboxPermission -Identity "Alias or Email of account removing rights TO" -User "Alias or Email of account removing rights FROM" -AccessRights FullAccess -InheritanceType All

PowerShell Remove Delegate Permissions O365
