Hi,
Got EX13 and EX07 in co-exist. Pointed all the external URL to EX13. ActiveSync proxies to 2007 and OWA redirects to legacy url with SSO. Working perfectly!
But with Outlook Anywhere it does not work. Mailboxes on EX13 works good, but not for EX07 user.
Error message from MRCA:
Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server "internalFQDN ofbackend EX07 server"
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.
