Outlook (New) problems with MS account

I have several email accounts set up in the New Outlook app. Everytime I open the app I'm getting 'access denied' error.
Normally after a few seconds it will work again but sometimes I have to quit the app and restart it.
If I try to read, send or delete an email I get the problem

Account is working fine on my Samsung Outlook app, and outlook.com is fine too.
All other email accounts are working in the app.
I'm receiving emails to the account so it's not the account itself.

It;s like there's some connection/authorisation error with the app as all other ways to access my email are working.

Can confirm it's not just happening with my account, also happening on another PC with a different MS account.

I Have also been having this issue and thus far no resolve, Its rather annoying but workable until they fix the issue, I hope this gives you some relief knowing its not just you :)

Seems to fixed now, must have been a server-side problem
