BobClementsThx for the reply.
Maybe I was not precisly enough, sorry.
We have installed Office 365 Version 2008 and now we are installing via MEMCM ADR the Office 365 2102 Quality Update (Build 13801.20864).
After we see in Program and Feature the new installed Office version.
BUT there a no folder, icons, shortcuts (for example Word, Excel) in the "LEFT" side of the start menu. Looks like there is no Office installed.
On the right "pin" area the shortcuts are gone as well.
Right now we have this problems on all devices which we have tried, except that one who have installed the Office 365 2102 feature update (Build 13801.20808) (MEMCM, ADR) first a few weeks ago.
Also we can reproduce the issue on a test client (Windows 10 20h2 x64).
