This seems to be an on going issue and it has gone back to early days when Office 365 was launch. We are currently having issues with MS Office application freezes and wants to open in Safe mode. Some users gets repeat of the issues.
We had apply all or some of post recommendations from Microsoft but yet the issue still exist. some use's have to repeat signing in to their Microsoft Account to be able to use Office.
I there a know issue between MS Office 365 and Webex meeting and Webex productivity Tool Add in to MS Office 365?
If there's a permanent solutions please send it this way so we can try. We spend millions on Microsoft products but, yet they always try to push and point fingers to someone else to blame instead of working on a fix.
