Outlook on Mac not showing attachments in email.

Thanks Pete - we have had the same issue with one of our email accounts. Then the emails stopped working on the MacBook altogether (no new emails came through on the mac for this particular account, but came through for other email accounts on mac and there were no error messages), but this particular email account was still working on the iPhone. We cleared the cache, rebooted the Mac and eventually deleted the email and tried to reload it. Outlook now doesn't recognize the email and won't reload it. Important to note, our email is not a Google Workspace account.
