Error Message on Search

When trying to use the search in MS Outlook on either the Inbox or the Sent Items folder I get an error message "messaging interface has returned an unknown error".  However, I can run a search on sub-folders of the Inbox.  I tried the detect and repair option but it made no differnce.  Can someone point me in the right direction?

Hello Nemetona,

1. If no joy, register two important Outlook files. Go to Start > Run and type regsvr32 OLE32.DLL
Do the same for INETCOMM.DLL

2. If no joy, an addin could be interfering. Disable Outlook Addins.  Go to Tools > Options > Other > Advanced Options > Addin Manager or COMM/Addins and disable the addins.

If you cannot open Outlook, do a search for and rename extend.dat file.

3. Check if an external program running in the background is interfering with Outlook. Check Firewall, antivirus, antispyware, antispam, and all Norton programs. Disable these programs one at a time.

4. If no joy, create a new Outlook profile.

5. If no joy, reinstall Outlook.  Go to Add/Remove Programs and highlight Microsoft Office. Click on Install/Uninstall.  A menu will pop allowing you to choose repair or reinstall.

Hope this helps!

war1:  I tried all your suggestions but unfortunatly it does not work.  I also noticed that I cannot create a new folder below the inbox either.  The seperate Personal Folders (which is at the same hierarchical level as Inbox) does allow me to search/create new folders.

That case the app should be fine, but the local NT profile is probably corrupted. You can try and take the time and headaches to narrow it down, or try the easy solution and rebuild the local copy of the profile....

I would go to rename the local copy of the profile....

My Computer>C: >Documents and Settings>YOUR USERID

and rename it to

My Computer>C: >Documents and Settings>YOUR USERID-old.

Then login again and retry it....

This will need to be done after a reboot, using another user account other than your current one. Just create a new temp user to do this with, and make sure it has admin rights.....

Then just log back in and retest. If all works well, then simply transfer the data from the UID-old, to UID folder..
Nemetona, did you create a new Outlook profile as I posted above?
