mail bounce problem
Posted on 2008-10-15
we have one exchange 2003 back-end server (standard edition with SP2) with one Exchange 2003 front-end server. We are doing a transition to Exchange 2007. today we have initiated the schema update activity and i ran the preparelegacy command which ran successfully, then after that i ran the prepareschema command which was also successfull. after that i ran preparead command which was also successfull. but on the same time when preparead command was running, i was reported that few users are unable to receive mails from anybody. while sending mails to them we were getting the error:
Your message did not reach some or all of the intended recipients.

The message was undeliverable because the recipient specified has changed address permanently and forwarding was not applicable
I don't know what is the issue, is it due to exchange 2007 preparation or some other problem. it is happening with only 5 users. i have checked the ESM and found that users mailbox were disconnected after running the cleanup agent. and while reconnecting to the actual user, we were unable to connect to the same user. we removed the exchange attributes and tried to reconnect , then ESM hangs up while reconnecting. and were getting following error:
Unable to update Mailbox SD in the DS. Mailbox Guid: c30c0b3d-3714-4108-8925-29705e8c1c30. Error Code 0x8004010f
with event id 9554.
Can you please help us in getting the error resolved at the earliest as one of the user is MD of the organization. please revert me if you need any assistance from my side
