Steps to Fix Outlook Not Syncing

1. Verify Internet Connection

The first step in solving Outlook syncing issues is checking your internet connection. No emails are possible without a connection, whether it’s through Ethernet, Wi-Fi, or mobile data. Simple checks include trying to access a website via a browser or using services like to ensure proper speed and ping rates. If you encounter an issue, reboot your router, check cables, or make sure your device is connected to the most stable network.

Tip for Mobile Users: On mobile devices, conflicts between Wi-Fi and data connections can occur. Ensure you are using the connection with the best connectivity for a seamless experience.

2. Check Offline Mode in Outlook

Accidentally enabling Offline mode in Outlook can prevent syncing. To disable it:

  • Open Outlook and click the Send / Receive tab.
