Your Outlook account settings are out of date in Mail or Calendar

Original: If you receive a notification from your Mail or Calendar apps that your Outlook account settings are out of date on your Windows 11/10 computer, then this post may interest you.

Your account settings are out of date

You may suddenly see a notification pop up on the bottom right side of the screen when you log in to your windows computer. Clicking on either of these, the pop-up notification or the link in the Action Center will open the Mail app. In the app, you will see a message with two options: Fix the account or dismiss.

Click on Fix account to let Windows 11/10 automatically fix the problem. You will see the following screen when doing so. Once the problem is fixed, the window will exit, and all will be fine! This worked for me.

Most people who have an out-of-date account usually have an incorrect password. To fix this, all you need to do is select “Fix account” in the notification bar at the top of the Mail or Calendar app. If your password happens to be incorrect, you will be prompted to update it. After you have entered the new password, simply choose “Done”.

There are reports that the “Fix problem” button is not working for some users. If that is the case, here are a few things you may want to try:

If you’re getting unwanted notifications, try restarting your computer and logging in with your Microsoft account. This might stop the notifications from appearing.
Did you change any of your mail account settings online? Maybe you changed your password. If so, make sure your latest password is the same on the web, in the Mail app, and in Outlook if you use it.
Your windows computer’s time may be inaccurate. You can change this by opening Control Panel > Clock, Language, and Region > Date and Time > Internet Time. Uncheck Synchronize with an Internet time server and set your system time manually.

If you still don’t see the notification or the Fix problem button still isn’t working, check to see if your internet connection is working.] Check to see if the notification still appears or if the Fix problem button now works.

You’ve run into an error with your password or certificate. If your password isn’t the problem, you may have a certificate error. If you see a message that says, “There is a problem with the server’s security certificate. The security certificate is not from a trusted certifying authority,” follow the steps in the linked post to fix the issue.
