I use macOS for, wait for it, MS Office.

Yes, LibreOffice in Ubuntu or Fedora are good enough technically, and there are same problems when exchanging documents with Office for Mac as there are with LibreOffice.

However, deflecting blame works. When exchanging files with someone and something is broken in LO, it is automatically fault of LO. When something is broken in Office for Mac, it is an uh-oh moment, as obviously it is the latest product from the same company, so the effort to resolve the issue is much more constructive.

Another reason is, that both Mail.app and Outlook are usable as Exchange clients (yes, I'm stuck with that, with IMAP disabled there :(). Evolution is a trainwreck. There is a plugin for Thunderbird, but it is a no-go, as it is a yearly subscription. One time price would be fine, but no way I'm going to pay yearly for using Exchange mail in Thunderbird.

This saved my bacon in a similar situation back in the day: http://davmail.sourceforge.net
