Problems loggin in outlook for desktop after enablin MFA

Hi, I've recently enabled MFA on as a tenant, but now i'm having a problem logging in to the outlook desktop app. Im the only one having this problem, other coworkers don't seem to have it, while also having MFA enabled on their accounts
I've already tried removing all credentials from credential manager, removing all outlook profiles and resetting the login credentials, clearing the tpm(instructed by MSC rep).
After resetting the tpm i got the wamerror 80090016 Key does not exist, while powershell says tpmready : true and tpmactivated : true (tpm version 2.0).
i used to have an old login menu for outlook without a mfa option and that got stuck in a sign in loop where it wouldn't login and keep asking for the login info.
I hope anyone can help me

Hi @FrankWesselsDSPSGroup-3825,

What's the version of your Outlook desktop client? Is it the same as the other coworkers in your environment? The detailed version information can be viewed via File > Office Account > About Outlook?
What error did you get when failing to login in Outlook with MFA?

Close Outlook and set the following registry key.

HKCU\SOFTWARE\Microsoft\Office\16.0\Common\Identity\

REG_DWORD

EnableADAL

0

If the above fails then try Clear the TPM
