Solution 10 – Check your security software

Firewalls and yourantivirus program softwaremay prevent you from being able to sync emails and even calendar events.

It isn’t recommended to permanently turn the security software off, but doing this temporarily will check if it is the actual cause preventing you from syncing emails.

If your computer or device is connected to a network, the network’s policy settings may prevent you from turning off your firewalls and antivirus software. If you disable your antivirus program, do not open any email attachments or click links in messages from unknown people.

Immediately after you’re done fixing connection error, re-enable your antivirus and firewall.

If you’re using Outlook, Office 365 or Exchange account, advanced mailbox settings won’t be there unless you set up the account using advanced set up.

Follow these steps to check advanced mailbox settings:

You can also change the following settings where applicable:

Note: If you’re using Exchange account that needs advanced settings, remove it, then add it back using the advanced settings.

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.

If your account settings are out of date, this can be due to an incorrect password.
