Fix: Error 0x80048bf5 in Windows 10 Mail App

The Windows 10 Mail app, along with the Windows 10 Calendar app and the Windows 10 People app, is considered to be one of the most sub-par parts of Windows 10 and has been buggy and broken throughout the many Windows 10 builds that have been released. Even though Microsoft has managed to fix some of the many problems that users of the Windows 10 Mail app have faced. However, some problems, such as the error message that states “We’re having a problem sending messages. Make sure you have a connection and your account info is correct and try again” and greets the user with error code 0x80048bf5, have not officially been fixed.

Thankfully, there are a few solutions that have proven to work for the majority of users who have suffered from error code 0x80048bf5 in the past. The following are the three most effective methods that you can use to combat error code 0x80048bf5:

Method 1: Disable any and all third-party firewall programs

The Mail app may be having trouble making a connection with the World Wide Web because a third-party firewall app is standing between it and a stable connection to the internet. If that is the case, simply disabling (or uninstalling) any and all third-party firewall applications on your computer will allow the Mail app to get through to the internet, effectively getting rid of error code 0x80048bf5. If it starts to work after disabling/uninstalling the third-party antivirus; then you can re-install it again (since that would reset the settings of the firewall).

Method 2: Rename the Comms folder on your computer

For some users who were experiencing problems such as error code 0x80048bf5 with the Windows 10 Mail app, renaming the Comms folder in the AppData section on their computer did the trick.

Close the Mail. Open File Explorer and go to C > Users > (Your Username) > AppData > Local.

OR type %appdata% in the run dialog (windows key + r)

0x80048bf5-1

0x80048bf5-2

Then click the Local folder. Look for a folder titled Comms.

Change the name of the folder to anything other than Comms – for example, Comms_old.

0x80048bf5-3

Open the Mail app, and as soon as it opens, the app will create a new Comms folder, and this should get rid of error code 0x80048bf5.

Method 3: Uninstall and then reinstall the Mail app

If all else fails, uninstalling the Mail app entirely and then reinstalling it from the Store may just be able to free your computer and Mail app from the grip of error code 0x80048bf5.

To uninstall the Mail app, first open Windows PowerShell in Administrator mode. To do so, open the Start Menu, type powershell into the Search bar, right click on the program named Windows PowerShell, and click on Run as administrator.

powershell as administrator1

When Windows PowerShell fires up, type in the following command:

Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online

0x80048bf5-4

Press the Enter. Close Windows PowerShell and open the old Store app (the one with the green tile), not the new Store app (the beta one). Using the Store app, reinstall the Mail. Restart your computer.

Once your computer boots up, set up and use the Mail app, and error code 0x80048bf5 should be no more.
