Outlook 2007: Drag and Drop of files into new mails does not work anymore

Dear experts,
I use outlook 2007 and windows 7 64-bit, both up-to-date. outlook 2007 is connected to exchange, thus uses an OST rather than a PST file to mirror the files on the server.

Since Wednesday, after reindexing my mail messages and files, I have lost the following functionality related to outlook:
- I cannot drag a file from an explorer window and drop it into a new mail message, in order to add an attachment to that mail, anymore
- i cannot use the right-click - Send to mail recipient shortcut on a file to automatically create a new message with that file attached. An error appears when Outlook is open, saying that the OST file is already in use by another process (obviously outlook itself or what???), if outlook is closed, absolutely NOTHING happens.

Really need help very bad.

Any helpful comments are welcome.

Perform a scan/repair on the ost.

I hope this helps,
Can you drag and drop in the outlook web access?

If you can, and since being exchange, it will be safe to close outlook, delete the ost, and open outlook.

It will recreate the ost file from the server.

I already had performed a scanost before, but now did it again on your recommendation.

I didn't know drag and drop of files from explorer to outlook web access could somehow work? OWA is a web application running in IE. I never noticed that it worked before, but anyway, it doesn't work now either. (tried to drag a file into an open new message window in OWA)

If you suggest that I delete the OST, I can do that.
What I did before is delete the exchange profile and recreate it - this is similar to your suggestion in that a new ost file (for example outlook2.ost) is created and all mails are downloaded from the server. But the old ost file (outlook1.ost) is preserved. Maybe I should delete all ost files?

no errors were found (checked the deleted items folder for the report) and the issue is not solved.
Sorry, i misread the question, about dragging from explorer..

What service pack is your office 2007 running?
Also, check outlook is your default mail program..


If that doesn't work, consider uninstalling and reinstalling the office suite.
robofixAuthor Commented:
it's SP2 and I already made sure that Outlook is my mail program.

Do you really think uninstall and reinstall will help?
Can't I do a repair install instead?

Any further suggestions, anybody?
Shreedhar EtteCommented:
Yes, you can try repair install.

started a repair install from the control panel. Did a reboot afterwards. Then I tested again and noticed that this didn't resolve the issue.
Can You Test With Right Click Run As Administrator This Location Outlook

Under Program Files (X86)\ Microsoft\Office\Outlook.exe

all suggestions posted here didn't help.

The solution I was advised by Microsoft support at TechNet consisted in recreating my user account and profile. I found no other way to restore the original behaviour.
