Salam, I am getting this error when trying to move my mailbox back to exchange 2003. I've moved all the mailboxes that were residing on Exchange 2010 databases but the final one (mine) is not moving :/. I've created a new database on exchange 2010 and it moved successfully there but still I can't do it. When I try to move it from Exchange 2010 EMC when it reaches 95% it outputs this error (MapiExceptionPartialCompletion: Unable to copy to target.). When I try to move it from Exchange 2003 it give this error (The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0526-00000000.) The reason why I'm doing this is that I want to uninstall Exchange 2010 and begin with a fresh installation. Thank you in advance, Kindest regards.

Hi Abdullah, I belive it due to stale of courrepted message in mailbox causing this failure. I would advise below step to fix this issue. 1: When start move mailbox from exchange 2010 ESM, select 50-100 value for skip courrepted message 2: If posible take a reboot of Exchange 2010 server and then try. 3: Check the output of dcdiag and netdaig at exchange 2010 when move mailbox fail. It will let you know if there is any issue of DC and network. 4: Check whether any move request is already pending with your mailbox, To do this launch EMC, navigate to Recipient Configuration -> Move Requests node. Right click the mailbox (If anyone is there) select “Clear Move Request”. You can select multiple mailboxes to clear the properties in a single task. http://www.howexchangeworks.com/2010/01/cant-move-mailbox-in-exchange-2010.html 5: If the issue still occure, then I recommend you try to export the mailbox to PST and then import them to Exchange 2003 (can use Exmerge) Hope it will help you to fix this issue Anil

Hi, Agree with Anil. Adding to what anil has suggested you can only specify 50 corrupted mails to be excluded while migrating through Move wizard. If you want to exclude more corrupted mails you will have to do it from Exchange management shell.

Salam, Thank you both, I've exported my mailbox first successfully. Now I am trying to move with 50 as a limit of bad messages. If this doesn't work, shall I disable the mailbox from Exchange 2010 and then create a new mailbox for my user from the Exchange 2003 Active Directory console? Or there is a procedure to follow? Because I noticed that when a move fails my mailbox dissappears from the Exchange 2003 System Manager, once I remove the move request and start a new once the mailbox pops there. Thank you again, Kindest regards.Abdullah^2

You can disable mailbox from exchaneg 2010 EMC and wait some time for replication, So you can use same SMTP address amd create it in exchange 2003 ESM. For Disable Mailbox : http://technet.microsoft.com/en-us/library/aa997210.aspx Anil

Salam, This is the log of the MoveMailbox here, I think I'll disable the mailbox :/.
