Ways to Fix Outlook Sync Issues on Windows 10

If you are unable to send or receive emails, you will need to ensure that you have access to your email server.

  • Make Sure That Your Device is Connected to the Internet: You will need internet access to send or receive email. So, make sure your that device is connected to the internet and it’s functioning properly.
  • Consider Sending Email via the Web: As most of the email service providers allow you to access your email through a website. Therefore, it is suggested to sign in to your email account through the website and check whether or not you can send and receive email there. If you are unable to do so, it means that there might be an issue with your email server. In such a case, you will need to contact your email service provider for support.
  • Consider Sending Email Using Another Application or Device: If you are using another email application, computer, or mobile device, you can also try sending and/or receiving email from such applications or devices. If you are unable to do so, it implies that there could be a problem with your email server. Here, you will need to reach your email service provider for assistance.
  • Check the Status of your Email Server: In case your email service provider doesn’t have a website and you are unable to configure your email on another application or device, you will need to reach your email service provider to check if your email server is accessible or not.
  • Check Your Security Software

Sometimes, security settings and software like firewalls and antivirus software might prevent you from synchronizing your email and calendar events. Although it is not suggested to disable security software permanently, disabling the software temporarily will allow you to determine if such settings or software are preventing you from synchronizing your email or calendar events in Outlook on Windows 10.

  • After that, you will need to deselect the check box next to the option that reads – Use the same name and password for sending email if your provider needs a separate authentication for sending email. And, then provide the outgoing server username and password.

Notes: If required, you may also need to change the following settings:

  • Make sure to select the check box next to Require SSL for incoming email if your provider requires SSL for incoming email option.
