Outlook 2021 LTSC - Won't start or find user details?

[Max_Power]

Attempting to deploy Office 2021 LTSC - everything works as expected except for Outlook. All other applications auto sign in, and the applications activate.

 

However.... When you click Outlook it launches the screen to sign in, you add your email address but straight away you get a "Something went wrong" error. You click Change Account Settings, select Office 365 and it simply cycles back to the "Something went wrong" error.

 

Product is licenced and activated

Checked all Autodiscover settings and they're correct.

Not being blocked by a proxy etc.

Outlook 2016 still works as expected.

There are no logs anywhere that I can find.

 

Any suggestions would be appreciated

Having the same issue after installing 2019 (which worked) and then deciding I might as well go to 2021!

 

Outlook splash screen just sits there on 'Loading Profile'...

 

Did you find a solution?

 

EDIT: Never mind! I went to control panel and used the Mail setup (Outlook) to copy the original profile and named it Outlook New, then chose 'Prompt for a profile to be used'

 

Started Outlook chose the 'New' profile and it came up OK... Strange thing is I've closed and opened it again... but this time chose the original profile and it has also worked...
