Outlook 2003 w/Outlook Connector sending message in infinite loop

I use Outlook 2003 with Outlook Live/Outlook Connector to access my Hotmail account. This morning a message sent to me a month ago started popping again into my e-mail box dozens and dozens of times. I've deleted the original message, added the sender to the blocked sender list, but it still comes and comes, many times an hour. It seems to be in an infinite loop. I've had this problem before when sending messages (usually with large attachments), but never had a message I received come back at me repeatedly like this.

I feel it may have something to do with the fact that I started Outlook Live on a new machine last night. This machine has been attempting to sync my Hotmail messages all day, with a lot of problems.

Any ideas? The message in question happens to contain a medium-sized attachment so this is clogging up a lot of bandwidth and space on my end, not to mention being really annoying having to delete this message constantly.

Thanks!

 

Did that already, the message is nowhere to be found on Hotmail. But it's still coming with a vengeance into my account, for 24 hours now. Do you think it has to do with me installing Outlook Beta 2007 w/ Outlook Connector on a second machine yesterday, accessing the same Hotmail data? This is when it all seemed to start. Incidentally, I'm having trouble downloading all my messages from the Hotmail server on this second machine (getting a timeout error in the Outlook Connector status box). Weird things. I seem to remember a MS tech person telling me a key-combination to zap the Outlook cache on startup one time, but can't remember what it was - maybe this would help?

Thanks.

 

Update: This seems to be connected to the second machine running Outlook 2007 Beta w/ Outlook Connector and accessing the same Hotmail account. When I closed Outlook on that machine, the looped messages stopped. I also noticed yesterday that other old message appeared (out of date) on the first machine when I first started Outlook on the second machine.

They are sharing the same internet connection/IP. Any ideas?

 

Thanks for your reply. I will look into this, but I kind of figured Outlook Live would handle this sort of thing; ie. keep all machines in sync a la an exchange server. That's my understanding, anyway. I have Outlook Live (Outlook plus Outlook Connector) running on both machines.
