Error 0x8007274c is displayed in Windows 10 when your system cannot sync with the IMAP account you specified.

The error usually shows up with the Windows 10 Mail app, though it can also be caused by Outlook. There is a corresponding error code of 0x80072726 which can also be displayed on some systems.

The error is due to the connection to the IMAP server being blocked, usually by a third party firewall. SVCHOST.exe sometimes crashes as well, preventing synchronization from taking place.

The messages are often displayed as:

“We are having trouble downloading messages. Please try again later. Error code 0x8007274c and 0x80072726”

To resolve the problem, you must remove any of the possible blocks to the IMAP email connection.

The way to do this is to first make sure that your email application is configured correctly, then that your connection is not blocked by your antivirus / firewall application.

If you can achieve this successfully, you should be able to receive emails through your chosen email client (be it Windows Mail or Outlook). The process should be relatively simple:


1. Temporarily disable any third-party firewall

If you have a third-party firewall (AVG / Avast / Kaspersky / Symantec), you’d better temporarily pause it. This way, you will be able to see if it is blocking the connectivity of your mail application to the IMAP server. You can do this by following the steps below:

  • Right-click the Antivirus / Firewall icon in the lower-right Windows taskbar.

  • In the menu that appears, search for “pause” or “temporarily disable”

  • Select for 10 minutes or whatever the corresponding option is

While this will leave your PC temporarily exposed, we can reboot after trying the mail app one more time.

Now you need to go to your mail app and see if it will download the email this time or not. Otherwise, it means that you must specifically allow the svchost.exe file in the main Windows elements.

2. Allow SVCHost.exe through Windows firewall

SVCHost.exe It is used by Windows to help the services work on your system. While this app generally works fine, it will sometimes crash because it tries to access files / services that it shouldn’t.

If you are still experiencing error 0x8007274c (or 0x80072726), you should try to make an “exception” for this application in Windows Firewall:

  • In the search bar at the bottom left of the screen, type “Windows Firewall.”

  • Click the application that appears first in the list.

  • In the menu that loads, select “Allow an application or function through Windows Firewall”.

  • Add a new application, with the directory URLs: – C: WindowsSystem32svchost.exe – C: WindowsSYSWOW64svchost.exe

  • Once it has been added, rename it to “Host Process for Windows Service” and then click “OK”

Then you have to test the Mail app again after this. If it works, then you have solved the problem (for now).

If not, you will have to go through the same process with Windows Defender …

3.Allow SVCHost.exe through Windows Defender

Windows Defender it is the default antivirus application that comes with Windows 10. If the above steps did not work, you will need to add svchost.exe to your excluded applications:

  • In the lower right corner of the taskbar, select the little blue shield and right-click

  • Select “Open” from the menu that appears.

  • Click on “Settings”

  • Scroll down to “Exclusions”.

  • Add exclusion

  • Select “” Exclude an exe, com or str process “and exclude the following: C: WindowsSystem32svchost.exe Y C: WindowsSYSWOW64svchost.exe

  • Restart your PC
