I have created a new user in AD and went to create a new Sharepoint Connection with that user name and password. Every time I test it I get the following error…
Test connection failed:
Can’t connect to the server. The sign-in name or password does not match one in the Microsoft account system.
Notes:
New account, no MFA
Logged in to Sharepoint through Microsoft with the new account.
It was enabled. Click on the policy name and disable it or add the names that you want excluded from blocking. I would not recommend deleting it just in case your admin had a good reason to have it enabled.
