Outlook 2003 error: 'C:\Documents and Settings\...\outlvba.dll' is not a valid Office Add-in

I have just upgraded 20 users from Outlook 2000 to Outlook 2003, and one of them now gets the above mentioned error when starting Outlook.  Ass upgrades were done by letting Setup remove outlook 2000 and install 2003 in its place.  When starting outlook, she sees the Windows Installer window first, with a message to "Please wait while Windows configures Outlook" and a progress bar.  This window replays anywhere from three to six times, and then Outlook starts.  Immediately after the Outlook window paints, the error pops up.  After clicking OK, Outlook runs normally.

Any thoughts on what could be causing this?  There is nothing in the Add-in Directory.

Thanks for any help you can offer.

Hi dcmathis,
> There is nothing in the Add-in Directory.

Did you check in here ?
open outlook
go to tools --> options --> other  --> advanced options --> COM add-ins
click on the add-in and remove it .

Hey SR,

There is nothing in the COM Add-in window, but it gives me the same error when I click the COM Add-ins... button.  Wierd, huh?

OUTLVBA.DLL is part of MS Office 2000 and can be found in C:\Program Files\Microsoft Office\Office\Addins\.  Maybe check the versions of this file between a working system and the problem system.

Another good idea.  I replaced the file with a copy of the one on my WS, and get the same message.

Any other thoughts?

There was the same problem with some 2002 installations...see here...


Looks like a bit of work.
Good Luck

Hello, Meinsti.

I followed the recommendations from the microsoft KB you referenced, but to no avail.  Apparently, there is something else at work here.  All of my users are set as power users, and the problem seems to have something to do with permissions.  If I change this user to an administrator, Outlook works just fine.  However, when she's set to Power User, she gets the error.  This is not happenning with any other users, nor is it happenning at any of our other offices.  I'm really starting to bang my head against the wall over this one.

Any other thoughts, anyone?

Few other ideas ....

Did you try a Detect & Repair?
Maybe the OUTLVBA.dll needs to be re-registered.
Is the addin disabled?    HELP - ABOUT OUTLOOK - DISABLED ITEMS
Is the troubled machine a differnt OS? ( or have different updates installed?)

Haven't done detect and repair since I did a complete removal and reinstall last night.

There are NO add-ins enabled at all,  hence my confusion over this whole thing.  

Machine is win2k SP4.  Just like the 17 others in this office, none of which have this issue.

I haven't registered OUTLVBA.dll.  Didn't on mine or anybody else's computer either.  

At this point, the error is just an inconvenience for the user, since Outlook runs normally after she acknowledges the error, but she's going to get tired of putting up with it soon, so I'd like to be able to make it go away.

Still fishing for help here.

Had the same problem, here's the fix I've found:

open regedit.exe

Navigate to the following key:

Export this key (just in case something stops working after you do this) and delete it.
Close outlook and open again. Then go to com add-ins and check for errors.

one addition: You may have to run the office detect/repair afterwards to make corrections in the installation.

Thanks, cconcle!  That's great.  Finally, the user can now look for something else to be upset about, lol.

Thanks again!

I had the same issue with two WIN2K machines.  I logged on as adminstrator and ran the repair from Add/Reemove Programs.  Took about 5 minutes, but it worked.  This does not appear to be an issue on XP machines.  Just WIN2K

Removing the registry key alone did not fix my problem, but running the Detect and Repair from the Help menu afterward did.
I was getting the error in the title of this discussion and I was not able to send mail - everthing would sit in the Outbox.
This is on a WinXP Pro SP2 machine.
My problem was not from a fresh install or upgrade - but from an in production machine that has been running fine for about 1 year.  This error just showed up one day.

With the following article i came much further

with this information i came to changing
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Microsoft.VbaAddinForOutlook.1\LoadBehavior to 17 (decimal) (original setting was 9)

and now it's working like a charm.
