At first my mouse was disappearing under the Outlook window, reading the forums, removing iTunes add-in helped with that.

Now however, the system just stops typing in Outlook365. Not having that concern with other components of the suite. Illse my work and have to restart Outlook. Have tried to restart as admin. Doesn't make a difference.

Dell Win 8.1

Please advise. Thank you

Hi,

Lots of Office issues are caused by third party add-ins. So I would suggest you first check result in Outlook safe mode and see if issue persists:

Press Win + R and type "outlook.exe /safe" in the blank box, then press Enter.

Also, please try to install any available updates, make sure your Office 365 installation is the latest version, check result.
