No, Microsoft Mail cannot be uninstalled and reinstalled since it is part of the Operating System.
But, it can be rebuilt.
There is currently no patch available for the problem of emails not dispaying and not allowing you to empty deleted emails or delete them one by one using the delete command.
I too, received the error code "Message could not be displayed
Outlook Express encountered an unexpected problem while displaying this message. Check your computer for low memory or low disk space and try again."
I tried several fixes and database repair programs to no avail.
The following process worked for me:
Make sure that Windows Mail is closed when you do the next steps.
Go to the folder C:\users\%your computer name\AppData\Local\Microsoft\ and copy the “Windows Mail” folder to another place on your hard drive for backup purposes so you will not lose any important emails.
Go back to the C:\users\%your computer name\AppData\Local\Microsoft\Windows Mail\ folder and delete ALL of the contents.
WINDOWS MAIL, SINCE IT IS PART OF THE OPERATING SYSTEM WILL REBUILD THE FILES NEEDED TO RUN.
Open Windows Mail.
In Windows Mail, Go to File-Import-Messages
Select Microsoft Windows Mail 7, select next.
Browse to the location that you save the backup copy of Windows Mail. Then select OK.
Your messages will then be imported back into Windows Mail.
You will notice a folder that will be called “Recovered Messages”
Now, depending on what folders you had, recreate those under the Local Folders heading.
Go back to the folders of the messages you recovered, you will notice messages that were not removable before still there.
THE FOLLOWING WILL TAKE SOME TIME, BUT WILL REPAIR YOUR PROBLEM.
Locate each email that has NO Heading and highlight each one and hit the delete key, they will be placed into your Deleted Items folder, you must not go too fast or try to highlight and delete them all at once or you will get the error message again,.
Once you get to the emails that you want to keep from the Recovered folders, highlight all the messages by clicking on the first one, holding down the Ctrl key and selecting the last one.
Right click on the messages you highlighted and click “Move to Folder”, then select the folder you want them moved to.
Once the files have been moved, delete to folder that they were moved from (Makes it easier to keep track of where you are at.
Then go to your Deleted Items folder, right click and hit Empty “Deleted Items” Folder.
Hope this helps.
It also helps to change your setting under Tools-Options in the tab of “Advanced” under “Maintenance” Where the heading of “Cleaning up Messages” is located, check the box for “Empty messages from the “Deleted Items” Folder on exit. That way, your emails are removed and hopefully the problem stays gone.
Let me know if it works for you.
