ThorConnWndClass problem

Hi. Running Office Standard 2007, I have the following problem: The send/receive sequence sometimes hangs on "Receiving message [n] of [n], [x] Kb" and I need to close Outlook. The icon remains in the system tray, but greyed out and with an X superimposed. On shutting down Windows, I get a window with an errormsg about "ThorConnWndClass" needing to be terminated, and with the usual countdown to automatically terminating it.

On this board I found one relevant thread. Whiskeyman referred an enquirer to two offsite threads. One gave a 404 error, but the other suggested reloading the original CD and removing the element "Alternative User Input ". I loaded the original Office CD, went for "add/remove features ", but nowhere could I find the "Alternative User Input" feature to remove it.

I had previously googled the problem and found many threads, but none seemed to have a workable solution, although there were dire warnings about the way this error could permanently corrupt the .pst file. Some suggested that "ThorConnWndClass" was part of a Norton program, but I have never, ever had anything from Norton installed.

Bonus question (which may or may not be relevant to this problem): I've noticed that, although I have send/receive set to "every 15 minutes ", Outlook in fact runs a send/receive sequence every 1:30 to 2:00 minutes approx - don't know whether this is relevant or is a totally separate issue.

Grateful for any guidance on this.

 

Thanks Arie - I did that and scanpst.exe found and repaired an error in the pst file. But - unless I'm mistaken - that doesn't address the cause of the problem, the ThorConnWndClass error, so the pst file may get damaged again.

BTW I forgot to say in my original post that I had also run the Outlook Diagnostics, but without ant effect.

 

Hi Steve and thanks for that. Your link didn't work for me, but I found the file anyway by googling "Personal Folders Backup site:microsoft.com" and installed it. However, even after a cold reboot, the option "Backup" still does not appear in the File menu drop-down list in Outlook.

And anyway, like Arie's suggestion, if I have understood this right, once I get this to work it will save the situation if the .pst file gets damaged, but does not address the original issue described in my first post.

 

Aha - that certainly changes things! Sorry, Arie: my (false) assumption from the various threads I had found on other boards was that a corrupted .pst file was the *result* of the ThorConnWndClass problem, and not the *cause*! Guess I was looking at this the wrong way round - thanks for clearing that up.

Anyway, I've now followed both your and Steve's advice - Hopefully the original problem won't recur now.

This leave just two minor points unresolved:

1. Although I installed the PF Backup app recommended by Steve, I still don't see "Backup" on the File menu drop-down list;
2. Outlook is still performing a send/receive cycle every two minutes or so. My contract is a flat rate type, so it's not costing me any more, but it's using resources I'd rather have available for other tasks. Should I make this into a separate thread, as it doesn't seem to have been affected by solving the original issue?

PS: In case it's relevant, I'm using Outlook Connector to have my Hotmail transferred across into Outlook. Might that be the cause of the rapid send/receive cycling?

 

Nope. Just the one group, "All Accounts ", set to 15 minutes. Still, as I said, it's not an extra cost, but it's bugging me that I can't solve it.
