Unable to add shared MS Exchange mailbox to Apple Mail
Hello
I am trying to add a shared Exchange mailbox to Apple Mail (Monterey) on the Mac mini (M1). I keep on getting 'unable to verify account name or password' error. I was on the phone to Microsoft for 1 hour today and we have the shared mailbox working on Outlook for Mac and Outlook web, but we couldn't get it working on Apple Mail.
I have followed instructions such as these and tried IMAP and other configurations (with Microsoft on the phone).
Grateful if someone has any information on how to make this work.
Thank you
Jamie
