Outlook is killing my productivity ! Its keeps flashing and is unusable

Hi,

Does anyone else have the issue where outlook just starts flashing and locking up,  then becomes unresponsive?  I end up killing it via task manager most of the time :-( I'm running Office pro Plus and I'm on first release (windows 10) etc any pointers of successful solutions would be great.

  • "Flashing" usually means an issue with the graphics driver, try toggling the File -> Options -> Advanced -> Display -> Disable hardware graphics acceleration setting. You can also try running Outlook in safe mode (hold the CTRL key while launching it or type 'Outlook /safe' in the run box). Recreating the profile doesn't hurt either.

      Thanks VasilMichev for getting back to me I'll give the display idea a try, as an aside I'm running a surface book so the chances are this could be the issues ;-)

        Curious, did this correct your issue?  I got a Surface Book 2 a couple weeks ago and have the same issue in Outlook. I've disabled the hardware acceleration now to see if that will work, but just checking to see if that did resolve your issue permanently?

        Thanks

      Thanks VM. I have been trying to find the resolution and disabling the acceleration worked on my SurfacePro running Outlook 2016.

    I fixed a few following the steps

    1 - I suggest you open another Office app (like word) and sign out of the account, then close all office apps

    2- Go to credential Manager and clear all the MS credentials stored there

    3 - Open Register Editor as administrator and follow the path Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity

    3a - Right click in a blank space and Insert New DWORD (32-bit) Value "EnableADAL"

    3b - Set the value for "0" and select "Hexadecimal"

    4 - Go to Settings - Apps - and Repair Microsoft Office App

    5 - Restart the computer

    6 - Open Outlook and Login again.
