I accidentally uninstalled windows live messenger a while ago, and no amount of attempts to download windows live essentials will bring it back. I noticed that the Outlook Pack, Bing Bar and Silverlight were not installed as well. WHAT IS WRONG T_T someone help me... running on 64bit windows 7.

I have a user that is moving from a Mac back to a Windows-based PC.

 

They have a large amount of (valuable) email that was imported into Outlook.

 

My understanding is that the import changes the data to another format, so they aren't really .pst files anymore.

 

Does anyone have any experience with this?
