So here's a solution to a problem...

Problem:

The macros I have written in my MS Outlook have suddenly vanished and don't seem to find it.

Solution 1:

Restart MS Outlook. Funny aint it? Yes. I think 80% of the problems in MS are solved by restarting, be is Windows or Outlook.

Solution 2:

The file VbaProject.otm is located in one of the below folder based on the OS.

Win XP: 

C:\Documents and Settings\%username%\Application Data\Microsoft\Outlook\

Win 8/7/Vista:

C:\Users\%username%\AppData\Roaming\Microsoft\Outlook

Backup:

C:\Users\%username%\AppData\Backup\Roaming\Microsoft\Outlook

So, just take the backup from folder and paste it. Make sure you do you it when Outlook is not running.

Start Outlook.
