O365 user change password then outlook 2016 client prompt blank screen and no response

Hi,

1. Perform repair with fully online repair.

2. No cache credential on windows credential .

3. MFA is disabled.

 

Any advise to fix the blank screen on outlook, it should be o365 login box . 

 

Thanks.

     One thing you can try which i often do for licensing office to the correct user. especially if an existing licence is registered to a previous user is the following:

     

    open command prompt as an Admin.

     

    enter: cscript "c:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus

     

    Press enter and you will see near the bottom 5 characters for the installed product. Make a note of these.

     

    then enter: cscript "c:\Program Files\Microsoft Office\Office16\OSPP.VBS" /UNPKEY:

     

    after UNPKEY: enter the 5 characters you observed previously and hit enter.

     

    Now reopen an office product and you will be prompted to enter your users username and office 365 password. This will re-register the product and hopefully resolve your issue.

     

    If you still not getting the authentication prompts id completely uninstall and reinstall via portal.office.com via the users login.
