I am in the process of upgrading our Exchange 2003 system to Exchange 2007. Everything has gone well, but I am having problems replicating across some of my Public Folders.
There are only 15 public folders total, 8 of them have replicated across fine but the other 7 do not want to know. For the 7 folders that do not work, when I try and check on the replication status, on the replication tab\details button on the folder properties sheet. I get the following error message:
An unexpected, unknown error has occurred, MAPI or an unspecified service provider. ID no: 80040605-0000-00000000. ID no: c1050605, Exchange System Manager.
I have check the permissions on the folders that do not replicate and they are exactly the same as the permissions of the folders that do. I have also checked the client permissions and every folder have an owner that is not default. I have run the Best Practice Analyzer Tool on both a health check and a permissions check and they both come up clean on both the 2003 or 2007 server.
I have not moved any users to the 2007 server yet, but the test accounts I have moved are able to send and receive mail, so the 2 servers can talk to each other fine.
