The 0x8007274c error appears in Windows 10 when the system can not sync with the specified IMAP account.

The error is usually displayed with Windows 10 Mail, though it may be caused by Outlook. There is an appropriate 0x80072726 error code that may appear on some systems

An error is caused by a connection to the IMAP server that is blocked, most of the third-party firewall. SVCHOST.exe sometimes blocks block synchronization

Messages often appear as follows:

"There was a problem downloading messages, try again later: 0x8007274c and 0x80072726 DTC"

[19659002] To resolve this problem, you need to remove any blocks through the IMAP e-mail connection.

This is the way you first make sure that the email application is properly set up, then your connection will not be blocked by the antivirus / firewall application.

If you can access it correctly, you will need to receive emails through the email client you selected (Windows Mail or Outlook). The process must be relatively straightforward:

1. It is prohibited to temporarily disable any third party firewall

If you use an external firewall (AVG / Avast / Kaspersky / Symantec) it is best to temporarily suspend it. This is how you can see whether you are blocking the connection of an email application to an IMAP server. You can do this by following these steps:

  • Right-click the antivirus / firewall icon in the lower-right Windows taskbar.
  • Select "Pause" or "Temporarily Disallow" from the pop-up menu
  • Select 10 minutes or the appropriate option

While temporarily disabling your computer, you can restart it after testing the mail application.

You must now search for the e-mail application and see if they are now downloading the email or not. If not, then it means that the svchost.exe file should be specially enabled in Windows key elements.

2. Enable SVCHost.exe through the Windows Firewall

SVCHost.exe works with Windows services. Although this application generally works well, it sometimes gets blocked because it tries to access files / services that are not allowed.

If you continue experiencing the 0x8007274c (or 0x80072726) error, try to "make an exception" of this application in the Windows Firewall:

  • In the search box that appears in the lower left corner of the screen, type "Windows Firewall"
  • Click on the first application
  • From the menu that you want to load, select "Enable application or service via Windows Firewall"
  • directory URLs:
    – C: WindowsSystem32svchost.exe

    – C: WindowsSYSWOW64svchost.exe

  • After adding it, rename the "Host Process for Windows Service" and click "OK" button

Then re-test the Mail app. If it works, you've solved the problem now (now).

If you do not, you must perform the same process with Windows Defender …

3. Enable SVCHost.exe with Windows Defender

Windows Defender is the default antivirus that belongs to Windows 10. If the above steps do not work, svchost.exe must be added to excluded applications:

  • In the lower right corner of the tray, select the small blue shield and right-click it
  • Select "Open" from the menu that appears
  • Click on "Settings"
  • Scroll down to "Exclusions" [19659013] Add Exclusion
  • Select an "exe, com or str operation" and close the following: C: WindowsSystem32svchost.exe and C: WindowsSYSWOW64svchost.exe
  • your computer
