How to Fix Mail and Calendar Error 0x8007054e

Now that you know what possibly could have gone wrong with your Mail and Calendar app, attempt these solutions. Try to apply these fixes in the same order as they were put in.

1. Restart your Windows PC

Many a time, you could not start an application simply because of some internal glitches. Restarting your computer is an effective way to resolve such issues and it might help you to get your Mail and Calendar app working again. So, we suggest reboot your device once and check if the problem is fixed now.

2. Delete the Comms folder

Several users reported fixing this error code after they deleted the Comms folder from the root drive (on which Windows is installed).

Instead of deleting this folder, we recommend renaming the Comms folder to something Comms.old and check if the error 0x8007054e resolves this way. Follow the below instructions on how to carry out this solution –

Press Windows + E to launch File Explorer.
Select This PC from the left navigation and navigate to this path on it –

C:\Users\Your_Username\AppData\Local\Comms

If you have restricted displaying the hidden files and folders on your PC, you have to first unhide all such files.
After you have enabled showing the hidden files and folders, you may navigate now to AppData\Local.
Once you are inside the Local folder, right-click on the Comms folder, and select the Rename option. Alternatively, one may also choose to delete this folder from his/her system.

Note: If you are getting an error “The action cannot be completed” while deleting or renaming the Comms folder, you need to first stop running the Mail and Calendar app from the Task Manager.

Use the “Ctrl + Shift + Esc” hotkey to launch Task Manager, and locate Mail or Calendar app under Apps. Right-click on the available app, and select End task.

After you have successfully renamed or deleted this folder, restart your PC.

From the next login, click on either the Mail or Calendar app and you will find the Comms folder regenerating inside the Local folder.

3. Run SFC and DISM Scans

The presence of corrupt system files or folders may also prevent the “Mail and Calendar” app from working as usual. If that’s the case, you should revoke all system files using System File Checker or DISM. Here’s how to proceed ahead with this solution –

Right-click on the Windows icon and select Terminal (Admin).
The UAC window will prompt next, hit Yes to authorize accessing the terminal.
The terminal will default load into Windows PowerShell having admin rights.
Copy/paste the following code on it and press Enter –

sfc /scannow

Wait for the System File Checker to find and repair corrupt system files on your computer.
After this is over, run the DISM codes on the same prompt. For this, copy/paste the following, and press Enter –

DISM /Online /Cleanup-Image /RestoreHealth

The DISM tool will check for any corruption within your system files and repair them automatically. After this is over, close the terminal, and restart your PC.

Now that the file corruption is resolved, check if you can start Mail and Calendar without getting into the same error code again.

Note: Windows Users may also open Command Prompt on the terminal. For this, they need to press Ctrl + Shift + 2, and the terminal will launch CMD in a new tab.
