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 .

 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.

The outlook client is 2016 home and business OEM edition. 

It doesn't require to activate with o365 account.
