Outlook 365 for Mac: missing FROM: field

Question

Recently we switched to Microsoft 365 as our email service provider. Later we created some aliases to our principle email address. On Outlook Web or Outlook for Windows I can activate "From" field easily and therefore send an email using an alias as sender.

However, on Outlook for Mac OSx, for some reasons I cannot find or activate the "From" option so can send only from a principle email address. How do I active "From" option in Outlook for Mac just as I can do on Outlook for Windows in order to send using an alias?

Solution

As I know, the FROM field will only display if you have more than 1 account configured in the profile. And it seem that Outlook for Mac does not support sending an email using an alias as sender like Outlook for Windows so far. We could only send emails from email accounts in the current profile.

Thanks, just got off the chat with MS support and they confirm that aliases don't work on Outlook for Mac. I ended up setting up sharedmailbox for Mac users.
