Every day at 03:30, when the server starts the "cleanup of deleted mailboxes that are past the retention date" (event 9531 in the Application log), I immediately get the following two error events logged:
Event 10001 - MSExchangeIS Mailbox - The folder with folder ID 1-57C7 could not be deleted. Additional information: 0x3f0.
Event 1203 - MSExchangeIS Mailbox - Failed to delete the mailbox of /O=DOMAIN /OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=BILL with error 0x3f0.
After going into System Manager, I see that there are two mailboxes for Bill. One is currently in use; the other one (with the deleted mark on it) has not ben accessed in over two years. My guess is that whoever set this up deleted Bill's account for some reason and then recreated it without purging the mailbox.
Any ideas on how I can get rid of the old mailbox at this point?
Thanks, in advance,
