Error 0x8007274c shows in Windows 10 when your system can not be synchronized with the IMAP account you specified.
An error usually appears with the Windows 10 Mail app, but it may also be caused by Outlook. There is a corresponding error code 0x80072726 that can also show on some systems.
Villain stems from the fact that the connection to an IMAP server is blocked, usually by a third-party firewall. SVCHOST.exe is also sometimes closed, preventing synchronization from occurring.
The message often displays as:
"We have trouble downloading messages." Please try again later. Error number 0x8007274c and 0x80072726 "
To resolve the problem, you must remove all possible blocks with the IMAP email.
The way to do this is to first make sure your mail application is properly installed. Your connection can not be terminated by your antivirus / firewall application.
If you can get this right, you should be able to receive email with your email server (whether it is Windows Mail or Outlook). to be relatively simple:
1. Turn off a third-party third-party firewall
If you have a third-party firewall (AVG / Avast / Kaspersky / Symantec), you'll be best temporarily pause. This way you can see if it closes the connection of your mail application to an IMAP server. You can do this by using the following steps:
- Right-click the antivirus / firewall icon in the Windows toolbar at the bottom right.
- In the menu that appears, look for "pause" or "off temporarily"
- Select for 10 minutes or whatever the corresponding option.
While this will cause your computer to be temporary, we can only restart after checking out the mail application once more.
Now you need to visit your email application and see if it will download the email this time or not. If not, then it means that you need to specifically enable svchost.exe file in kernel windows.
2. Allow SVCHost.exe through Windows Firewall
SVCHost.exe is used by Windows to assist the service of the system. While this program works well, it will sometimes be closed because it tries to open files / services that it should not.
If you are still experiencing 0x8007274c (or 0x80072726) error, try an "exception" for this program in Windows Firewall:
- In the search box at the bottom left of the screen, enter "Windows Firewall" [ Click on the application that appears first on the
- list In the menu that is uploaded, select "Allow applications or features with Windows Firewall"
- Add new applications with folder paths: -C: WindowsSystem32svchost.exe -C: WindowsSYSWOW64svchost.exe
- After it has been added, rename it on "Host Process for Windows Service" and then click "OK"
You should try the Mail app again after this. If it works then you have resolved the case (now).
If not, you must perform the same process with Windows Defender …
3. Allow SVCHost.exe through Windows Defender
Windows Defender is the default antivirus program that comes with Windows 10. If the above steps do not work, you need to add svchost. exe to barred programs:
- Select the right corner of the taskbar, select the small blue screen and right click on
- Select "Open" in the menu that appears
- Click "Settings"
- Add barring  Select "" Exclude exe, com or str process "and exclude the following: C: WindowsSystem32svchost.exe & C: WindowsSYSWOW64svchost .exe
- Reboot Your Computer
