After getting a few questions on Shared Mailboxes, and how you can manage them in Exchange Online as part of Office365, I decided to group a few of these questions and answers into this blog post.
More info on how to do this, please check out this URL: http://technet.microsoft.com/en-us/exchangelabshelp/ee441202
In the example below, I’m creating a new shared mailbox called Info.
New-Mailbox Info -Shared
Opening the Exchange Management Console, connecting to Exchange Online, go down to Recipient Configuration, and selecting your Shared Mailbox, will give you the ability of managing Full Mailbox Access:
Granting Full Access only enables a user top open the Shared Mailbox, and does NOT provide the ability of sending mail as that Shared Mailbox, or send mail on behalf of that Shared Mailbox.
and assign a value to –GrantSendOnBehalf to. In this example I have created a Distribution Group, and I have granted this group send on behalf permissions on the Shared Mailbox Info.
When Ilse sends a message as Info, the message will be received as:
In order to be able to see who did send this message, you will need to enable auditing before-hand, using the Exchange Management Shell cmdlet Set-Mailbox!
Now when someone sends a messages as Info:
The message will be arrived as:
To track who really sent this message, run the following line in Exchange Management Shell:
Search-MailboxAuditLog –Identity Info –LogonTypes Delegate –ShowDetails
