How to Rectify Outlook’s Non-Synchronization in Windows OS

While Microsoft Outlook is a popular email client among Windows users, it’s not without its flaws. Sometimes, Outlook can put a dent in your day when it fails to sync your emails on Windows.

Instead of switching to another email client or starting from scratch, consider applying the following fixes to resolve Outlook sync issues on Windows.

1. 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 theSend / Receive tab and click theWork Offline button. Outlook will connect to the server and start syncing data.

2. 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 theJunk 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 selectJunk > Not Junk .

If you want Outlook to recognize the sender as trustworthy, select theAlways trust email from [sender] checkbox and clickOK . After that, Outlook will show all the emails from that sender in your inbox.

3. Review Your Email Sorting Options

Typically, Outlook places newly received emails at the top of your inbox. However, if you have previously set up a specific sorting arrangement for your messages, older emails may appear at the top instead. This may give the impression that Outlook app is not syncing properly on Windows.

You can modify the sort options in Outlook so that it displays your new emails at the top. To do so, navigate to yourInbox in Outlook. Click the sort drop-down menu and choose theDate option underArranged by . Then, selectNewest on Top at the bottom.

5. Check Your Blocked Senders

Is Outlook not showing emails from a particular sender? That could happen if you have accidentally blocked the sender. To avoid any confusion, you should check the Blocked Senders list in Outlook and make sure none of your trusted senders are on the list.

Here’s how to do that:

  2. Type**%localappdata%\Microsoft\Outlook** in the text box and pressEnter .
