I hope you can help with this.
We are currently working on migrating from Exchange 2007 to 2010. As such part of the process involves moving mailboxes back a forth whilst we test certain factors. However we have noticed that some corruption occurs to mailboxes going back from 2010 to 2007?
We seem to always get the error
"Warning: Failed to reset the target mailbox after the move.
Error details: Not connected."
After which sometimes the mailbox becomes inaccessible
Any ideas why this occurs as i thought migration between the two exchange versions was supported?
