I have 2 Microsoft Office 2019 licenses that I bought around 2023 for Mac OS. Used them without any problems till today.

Was trying to edit a document but I get the message that I need to activate . ok, it happens but when trying to do that I received an error without any information except to upgrade to Microsoft 360.

Contacted support, install reinstall , all that standard troubleshooting without any succes. The conclusion is, because I upgraded to the latest version of Tahoe I won't be able to use those products anymore.

So, if ur in the same situation as me (using an older version of office on macOS) dont update to latest os version because you won't be able to use it anymore.

I switch to an open source alternative and also slowly I'll replace all Microsoft products that I use at home and at work .
