When running the message store configuration wizard my exchange store is not showing up. I have run the PW and selected the mailstore that I want to use. I recently went from a 2003 exchange store to a 2007 exchange store and I now want to go back to the 2003 store. The only problem is that the only mailstore that will show up now is the 2007 store. I have tired running the PW a few times and this is what TAC suggested, but I am still having issue. Thanks for any help! Jason
