Office LTSC 2021 - Stop automatically signing-in

[Koldov]

After installing I opened Excel and noticed that I was 'signed-in' to a '[email protected]' account...

 

There is no such Microsoft/Office 'account'... anyway I signed out (sure I've seen this before with other Office versions) and thought that would be the end of it as usual.

 

However, it carried on signing me in every time I opened an Office application! After a bit of research I found Credential Manager in the 'Control Panel' in Windows and deleted the entry for Office, hoping that would be the end of it...

 

Today I opened Excel and found it had signed me in with an email account (possibly from signing in to Outlook?)!!

 

I want a standalone Office install, not an all signing and dancing cloud connected, files everywhere Office (which is why I chose LTSC 2021), the account it signed me in as isn't even a real thing we use as it's just a 3rd party email provider account... I don't want it being 'helpful' and stashing away possibly sensitive documents to some random account in the sky!

 

How do I break these links?

At a guess as Outlook is part of the office suite, it would just grab those credentials.
