We have an Exchange 5.5 and Exchange 2003 systems. We are migrating over to Exchange 2003 and noticed that anyone accessing the calendar of an Exchange 2003 mailbox from and Exchange 5.5 mailbox is not viewable. The errors recieved are default folder is not found, or Network is preventing connection to this exchange server. We can ping the server, we can open other 5.5 accounts.
2003 mailboxes can see 2003 mailboxes.
5.5 can see 5.5
5.5 can not see 2003
any ideas would be help full
