Outlook keeps asking Password

Outlook keeps asking for passwords for all users in my Tenant. Another tenant id is working fine in our outlook.

Outlook Version - O365 and 2016

I have already done these steps for resolving that.

Troubleshoot by SAR tool

Reinstall office

Change registry setting as per Microsoft support tells us.

Tried to create a new profile but not configure

Multifactor authentication On and Off

Modern Authentication On and Off
