Hi<br />
I'm just completing an Exchange 2003 to 2010 transition, all seems to have gone well but we're seeing a shared calendar issue where users on 2010 accessing a 2003 users calendar only sees entries as &quot;busy&quot; or &quot;tentative&quot; but from 2003 to 2010 they can see full details, I migrated my mailbox yesterday to 2010 and I can still see all calendar entries on 2003 users but my colleague with the same domain/exchange permissions can only see &quot;busy&quot; on 2003, stumped......

Exchange 2003 to 2010 migration

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
