EX2010 Edge Sync Failure
Posted on 2011-05-06
EdgeSync service cannot connect to this subscription because of error "The LDAP server is unavailable"
I get this error when running test-edgesynchronization. It *was* working, and suddenly failed. No other symptoms, mail flow is fine. In the Edge server's TMG logs, I see successful connections to the Edgesync / LDAPS ports. No DNS lookup issues, HT can find the internal IP of the Edge server w/out issue and vice versa.
Running 2008 R2, TMG 2010, Exchange 2010 SP1. Hub Transport / Mailbox Role server on internal network, Edge Transport server running in DMZ.
