Troubleshoot: sending from the shared Sales mailbox fails
A salesperson can open the shared Sales mailbox but cannot send mail as it, while a colleague can. Compare the two permission lists, find what is missing, and grant exactly that.

The report
From Maya Brooks, Sales
I cannot send from the shared Sales mailbox
I can open the Sales mailbox in Outlook and read everything in it. But when I send a message from [email protected] I get "You do not have the permission to send the message on behalf of the specified user." Luis can send from it just fine. I did not change anything.
Impact: Customer quotes are going out from Maya's own address instead of Sales, and some customers do not recognize them.
What you will do
4 tasks1.Connect to Exchange
Mail permissions are managed in Exchange Online.
2.See who can open the mailbox
Check who has access to the Sales mailbox, and whether Maya and Luis are both on the list.
3.See who can send as it
Opening a mailbox and sending as it are managed separately.
4.Make the change
Give Maya exactly the permission that is missing and change nothing else about the mailbox.
