Hi experts

Im getting the error - "The file is corrupt and cannot be opened", when opening office attachments in outlook 2010.

Ive tried disabling the protected view options in office which hasnt fixed the issue, the only suggestion I have seen which Im sure would work is to delete the user profile and recreate. This seems a bit over kill to me, does anyone know what files I need to remove to fix the issue.

Thanks

Couple steps you may apply...

1. Repair the offline file with a Microsoft utility called SCANOST.exe. Ive seen this file reside in a number of different
locations, mainly within Program Files. It might be best to search for it with Windows or Google Desktop. SCANPST.exe will also work, though youll have to go digging for your outlook.ost, which should be near c:\Documents and Settings\ %profile %\ Local Settings\ Application Data\ Microsoft\ Outlook\ outlook.ost. 
If your file is significant in size, youll save a lot of time with the repair operation by not creating a backup. Because if the repair finishes successfully and Outlook still bombs, youll need to;
2. Shutdown Outlook completely, including any runaway outlook.exe processes in the task manager. Open Mail in the Control Panel and before you delete your profile completely, write down the server settings! Theres no need to worry about backing up your mail as its stored on the Exchange server. (Essentially, youre deleting that outlook.ost when you drop your mail profile.) Now, start Outlook and it will create a new profile, where youll configure the server with the information you wrote down previously.
3. If nothing helped even other methods from Microsoft, use third party software
