Why is my email account not syncing with my calendar or contacts?

1. Check to see if your email account is set up in the tools you’re trying to use.
2. Verify that all log-in credentials, such as usernames and passwords, are correct and match with the settings.
3. If you had recently changed your password, ensure it is updated in the tools you are trying to use.
4. Check the email settings in the applications or devices you are using.
5. If you are using a third-party email client, ensure the incoming and outgoing server settings are correct.
