Zoom Outlook Add-in has no valid digital dignature
I tried to add the Zoom for Outlook-Add-in to my Office 365 Outlook. I followed all steps, at the end I'm receiving the following error message: That didn't work This Office-Store-App cannot be installed as it does not have a valid digital signature. I tried several times, and it worked for years before. Can you please support, the add-in is an essential efficiency driver for my daily work. Thx!
