Outlook 365 - sending on behalf of another email address
We have a user email@example.com who has a full email account and supports Joe Smith.
Joe Smith has 2 emails. JoesOffice@domain.com and JS@domain.com.
JoesOffice@domain.com is setup as an alias and is set to forward to firstname.lastname@example.org. Those emails come in and Bob forwards those to Joe when he needs to see them.
If Bob wants to reply to or send from JoesOffice@domain.com (on Joe's behalf), Bob tries to send and gets a pop-up that says he does not have permissions to send on behalf of JoesOffice@domain.com even though the permission has been granted.
We double checked the permission and it was granted, we unchecked it and put it back on and it still does not work.
Anyone have any idea why we would have this problem?
