How to Fix 0X8007274c Windows 10 Error


The error 0x8007274c indicates in Windows 10 when your system cannot sync with the IMAP account you specified.

The error usually appears with the Windows 10 Mail app, although it can also be caused by Outlook. There is a corresponding error code of 0x80072726 that may also appear on some systems.

The error is caused by the connection to the IMAP server being blocked, usually by your third party's fire. SVCHOST.exe is sometimes blocked, preventing synchronization.

Messages often appear in the form:

"We have a problem downloading messages. Try again later. Error code 0x8007274c and 0x80072726 »

  • To resolve the issue, you need to remove one of the possible blocks in the IMAP mail link.
  • To do this, first make sure that your mail app is set up correctly, and then that your connection is not blocked by your antivirus/firewall app.
  • If you are able to achieve this correctly, you should be able to receive emails through the email client of your choice (whether it's Windows Mail or Outlook). The process should be relatively simple:


1. Be able to temporarily activate any third-party protective wall

If you have a third-party wall (AVG / Avast / Kaspersky / Symantec), you can pause it temporarily. This way, you will be able to see if it is preventing your mail app from connecting to the IMAP server. You can do this using the following steps:

  • Right-click the antivirus/firewall icon in the lower right bar of Windows.
  • In the menu that appears, look for "pause" or "temporarily disable"
  • Choose for 10 minutes or whatever the appropriate option

Although this leaves your PC temporarily exposed, we can simply restart after trying the mail app again.

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

2. Allow SVCHost.exe through Windows Firewall

svchost.exe used by Windows to help services run on your system. While this requirement usually works well, it will sometimes be blocked as it tries to use files/services that it shouldn't be using.

If you encounter the error 0x8007274c (or 0x80072726), you should try to create an "exception" for this application in Windows Firewall:

  • In the search bar at the bottom left of the screen, tap on "Windows Firewall"
  • Click the app that appears first in the list
  • From the menu that loads, select "Allow an app or feature through Windows Firewall"
  • Add a new application, with the directory URL:
    – C: WindowsSystem32svchost.exe– C: WindowsSYSWOW64svchost.exe
  • Once added, rename it to "Pending Windows Service Process" and then click "OK"

After that, you need to try the Post app again. If it works, you've fixed the issue (for now).

Otherwise, you will have to perform the same process with Windows Defender ...

3. Allow SVCHost.exe via Windows Defender

Windows Defender is the default antivirus application that comes with Windows 10. If the above steps didn't work, you'll need to add svchost.exe to its disabled apps:

  • In the right corner of the taskbar, select the small blue shield and right-click
  • Select "Open" from the menu that appears
  • Click on "Settings"
  • Go to "Exceptions"
  • Add exception
  • Select "Exclude exe, com or str process" and exclude the following: C:WindowsSystem32svchost.exe&C:WindowsSYSWOW64svchost.exe
  • Restart your PC
