Hello All,I have been doing a lot of looking on this and have found lots of articles on this issue. However I think that I need more some more help as the problem still persists. Here is the situation:I moved a user mailbox from one mail store (with restrictive limits) into another mail store (without restrictions to limits) becuase they filled up their quota and needed to send out emails. After the move the user was again able to send out emails. The next day the users Outlook 2007 SP1 could not connect to the exchange 2003 SP2 server. Looking into Exchange System manager is showed that the mailbox was disabled. Only options were to reconnect or purge and the reconnect would not allow him to connect. So I copied the users email into a PST and then purged the mailbox from the server.I used Exchange tasks to delete mailbox and then removed exchange tabs. I then proceeded to create a new mailbox for the user which completed successfully. However I would get the dreaded Event ID 1205 stating that: Failed to create the mailbox with error code 0x50c. I have gone as far as deleting the user and the mailbox. But now the problem I have is even if I create a complete different user and mailbox I still keep getting the same messsage that "Failed to create the mailbox" for the original user. Is there somewhere that I can tell exchange to stop trying to create that mailbox?Any help would be greatly apreciated and sorry for the long post.Cheers,
