I have a sbs2008 box that's using exchange 07. Every user can set out of office replies no problem except one user.
This user is out of the office connecting using HTTP over RPC. Works just fine. This is however not their primary account, they have another exchange server using HTTP over RPC as their primary, which is also working just fine.
The user is able to set out of office replies on their primary account no problem, but the 2nd account it gives the error message "Automatic reply settings cannot be displayed because the server is currently unavailable. Try again later."
Both servers use self signed certificates. Everything seems to work flawlessly except for the automatic replies on the 2nd exchange account.
Things to note:
1) Primary Exchange account is the same domain as the computer is joined to.
2) Secondary Exchange account is on a diff domain than the computer is joined to, PC is on Domain 1 (exchange acct 1).
3) Same domain users are able to set automatic replies no problem, but are internal users, joined to the domain, perhaps that makes a difference, or perhaps because they are on the same LAN? (maybe it's a dns problem, but making a host file change on that pc could possible break exchange account 1 from working?)
