Sending mail - Unable to get Shared Mailbox to show in "From" field (Outlook Online)
(Context: Office 365 E1 / Outlook Online) I have a shared mailbox that I need to be able to send from. My user account is properly set up as a member of that shared mailbox, and I am able to open...
What you have to do is remove your e-mail address and then add the shared mailbox one...I have done this several times and works like a charm
This worked for me.
