Mektozo , Just another Contoso ! :)

I had a very strange issue, i  installed Microsoft office 365 on demand and then uninstalled it, after that i found that the ribbon completely disappeared from Outlook 2010, reparing or re-installing Outlook 2010 didn't help, after a bit of googling i found this TechNet forum post, http://social.technet.microsoft.com/Forums/en-US/outlook/thread/8578021b-f34b-4d2f-9f7a-fa15674aa998/ all you have to do is as follows: 1. Close Outlook 2. Go to Start-Run type in Regedit 3. Navigate to HKEY_CLASSES_ROOT\TypeLib\{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52} 4. Right click on the 2.5 and 2,7 regkeys and choose Export. Save this export to your desktop for now so we have a backup. 5. Now once that is backed up right click on the 2.5 and 2.7 regkeys and choose delete. 6. Launch Outlook, outlook will start in repair mode after that Outlook should work well and the ribbon should appear !
