I migrated an Exchange 2007 mail server to a new Exchange 2010 server on a new domain. The mailboxes are all working well, however there is a Public Folder calendar that I'm having issues with. All of the meeting invites have copy listed in front of the name (a minor annoyance).
The real issue is that it doesn't resolve the users on the old domain to the same users on the new domain. This means when somebody updates an entry it doesn't send the update to the attendees.
I have been messing with this and trying to figure out if I can use MFCMAPI to resolve this issue but I am not having any luck. They have been using the calendar and making updates to these entries and those updates cannot be lost. Any ideas on how to resolve this?
