Message Could Not be Displayed WLM Encountered an Unexpected Problem While Displaying this Message: How To Fix

After upgrading Windows, Windows Live mail app may stop showing the content of the messages. When you try opening an email it will display this error message: "Message could not be displayed. WLM encountered an unexpected problem while displaying this message. Check your computer for low memory or low disk space and try again." 

Here is what you may do to fix it (it worked for me when I upgraded to Windows 11). In short, you need to add these three DWORD entries into the registry: 
RecreateFolderIndex   1 
RecreateStreamIndex  1 
RecreateUIDLIndex    1 

I'll show you step by step how to do it. But first, I want to remind you that if you modify the registry incorrectly the system may become unstable. Therefore, to be on a safe side backup the registry before you modify it. You can then restore it if you did it wrong. Here is a link on how to backup registry . The best thing is to let a computer pro do it for you. Otherwise, you do it at your own risk: see my Disclaimer.

1. To edit registry open search box from START menu and type RUN. In the RUN dialogue type “regedit” and hit OK (you may need administrative rights to open regedit).
 



2. Once you opened the registry navigate to the following folder and click on it:

   Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows Live Mail

3. Select EDIT>NEW>32 Bit DWORD
4. Name the newly created key: RecreateFolderIndex
5. Right click on this key and select MODIFY.
6. In the open dialog "Value Data" change from 0 to 1.
7. Repeat steps 3-6 for RecreateStreamIndex and RecreateUIDLIndex 
8. Close REGEDIT.
8. Close Windows Live Mail and re-open.

Note. If your registry already have the above three keys, you just need to modify their value from 0 to 1.
The content of the emails should now appear (you may also need to restart the computer).
