Solution 13 – Check Two-factor authentication

The two-factor authentication function protects your account from being infiltrated by outsiders or unknown people.

It’s a means of protecting it from others accessing or signing into it, by verifying your identity using a password, plus a second method like your contact or security information.

Mail and Calendar apps on Windows 10 do not support the two-factor authentication, so if it is turned on for your account, create an app password for the account, which will be used instead of your normal password for apps that don’t support two-factor authentication.

Check with your email provider on how to do this.

Solution 14 – Check account settings if they’re outdated

If your account settings are out of date, this can be due to an incorrect password.
