If your Windows 10 Mail app is not syncing automatically with Outlook.com, here are a few troubleshooting steps that will help you fix the sync issues.

Whenever any syncing issues are experienced, it is most advisable to update your Outlook Mail app and Windows 10. At times, such issues are addressed in the cumulative updates that are rolled out by Microsoft hence make sure  that you have all the latest version of the OS and the Mail app installed.

You may want to also first open Settings > Privacy > Calendar and ensure that the Let apps access my calendar setting is turned On. Having done this, ensure that you have set up your syncing settings in Mail app properly.

Now, if you’ve set up your account on Mail and Calendar app for the first time, the Operating System has to fetch the emails and calendar entries from your mail server, which may take some time due to content size and type. If you are still facing the issues even after 30 minutes, you can try the below steps to fix the syncing problems.

1. In Mail app, choose Settings and then select Manage Accounts. Choose the account for which you want to synchronize.

4. Click Done and then press Save to get your settings onboard.

Now, it should take some time to get the older content from the email servers and syncing the same in your registered mail account in Outlook Mail app.

Sometimes, you are not able to select the option Change mailbox sync settings as it gets grayed out. Well, this is temporary as the account might be under some syncing operation at that time which prevents you from accessing the sync settings for security reasons. You can retry after some time when the option is back in play.

Finally, you may want to check if your security software is in any way blocking the syncing from taking place.
