We recently upgraded from Exchange 2003 to Exchange 2007. After which it seems that the public folders that we had created on the 2003 box didn't move to the new servers. After creating the new servers it also seemed that we couldn't mount the store on the old exchange box. I created a backup of exchange with ntbackup and then formated the old exchange server. After setting that server back up with Exchange 2003 it wont let me edit any of the properties in ESM. i get a message that say:
"Exchange System Manager Version 8.0.30535.0 or greater is required to edit this object"
currently Exchange 2003 uses "6.5.7638.1"
is there a way to upgrade ESM to this new version?
