How to solve Outlook error 53003 when starting up?

Question

Everytime I open outlook it takes a long time, and then it asks to enter my corporate credentials only to finally tell me that:

"You dont have access to this"
"Your sing-in was successful but you dont have permission to access this resource"

The details tell me to show this to my systems adminstrator.
Unfortunatelly my system support dont have any idea of what this is and insist that I need to reinstall the whole microsoft office suite, which seems a lot more throublesome.
Can someone give me a hint of what is the issue and how to work around it?

The error details are:

Answer 1

This is a conditional access policy. You will have to consult with your IT Administrator to see which Conditional Access Policy is being applied to your account. It may be a location policy, but it is best to check with your team.

Have them check for sign-ins on your account and look up "Conditional access: Failure"
