2. Disable Offline Mode

Sometimes, the most effective solutions are those that appear too simple to be true. If you have accidentally enabled offline mode in Outlook, the app will not connect to the servers and sync your data.

To disable offline mode in Outlook, switch to the Send / Receive tab and click the Work Offline button. Outlook will connect to the server and start syncing data.

3. Check the Junk Folder

Outlook, like most email apps, has a spam-filtering feature that automatically identifies suspicious emails and sends them to the Junk folder. Hence, it's a good idea to check the Junk folder in Outlook to see if any of your missing emails have been directed there.

If you find any email that you want to move to your inbox, right-click on it and select Junk > Not Junk. If you want Outlook to recognize the sender as trustworthy, select the Always trust email from [sender] checkbox and click OK.
After that, Outlook will show all the emails from that sender in your inbox.

4. Repair Your Email Account
   Temporary issues with your account can also prevent the Outlook app from syncing your data correctly. Fortunately, Outlook includes an account repair option that can automatically detect and fix any issues with your account. Here’s how to use it.

   1. Open the Outlook app and click on File.

   2. Switch to the Info tab.

   3. Click the Account Settings drop-down menu and select Account Settings.

5. Clear the Outlook Cache
Overwhelming cache data can also prevent the Outlook app from working correctly on Windows and lead to sync issues. If the issue is indeed caused by corrupt cache data, clearing it should help. Since clearing the cache does not affect your data, there’s no reason not to try this.

To delete Outlook cache data on Windows:

• Press Win + R to open the Run command (see how to open the Windows Run dialog box for more).

• Type %localappdata%\Microsoft\Outlook in the text box and press Enter.

• In the RoamCache folder that appears, press Ctrl + A to select all the files and click the trash icon at the top to delete them.
