This issue applies to Outlook, Exchange Online, and Outlook for Microsoft 365.īased on the two scenarios listed below, you’re prompted for credentials, and Outlook doesn’t use Modern Authentication to connect to Office 365 – after you enter your credentials, they’re transmitted to Office 365 instead of to a token. In this post, we will look at why Outlook prompts for passwords when Modern Authentication is enabled, and as well as provide the solution to remediate this issue.

Open Outlook again, and now it should connect to the mail server without asking to enter your credentials.Modern Authentication is a method of identity management that offers more secure user authentication and authorization. Search for the Outlook saved credentials under “Generic Credentials” and then click on Remove. Close Outlook, and then do a search for Credential Manager on the search menu, open it and then select Windows Credentials If your Office suite is updated, then remove the old account credentials from the credential manager vault. I think this is a bug that needs get fixed by Microsoft. If you are using Outlook 2013 or 2016, make sure your office suite is up to date. I don’t know if the issue also occurs in Outlook 2016 or so.

These users are using Outlook 2013 with Windows 10. The reason why this happens is because when they get prompted to enter their username and password while using Outlook from home, and click the “Remember my credentials” option the account information gets save in the Credential Manager Vault and it doesn’t get updated when they are forced to change the password, but Outlook still tries to authenticate using the credentials saved in the vault.

We have a company policy enforcing people to change their passwords every 180 days, so when they change their account password is when they start having this Outlook issue.
