I am running the Interorg Replication tool on an Exchange 5.5 server. I am trying to replicate the free/busy time to a seperate Exchange 2003 organization, however it fails everytime. This is the error that appears in the log: ERROR: Unable to Initialize MAPI interface. I am also running the free/busy update from the Echange 2003 org to Exchange 5.5 and it works fine. I have created one account in each organization and verified that the mailboxes work. The accounts are simply domain users and they run the exssrv.exe on each respective server. The permissions have been properly set on the ExchSyncSecurityFolder. Any ideas? I can provide more info if needed.
