I have just deployed a new instance of Exchange 2019. Active Sync works fine (outlook and owa) and mail is processed ingress/egress fine. After enabling the IMAP services and associating the self signed certificate with the IMAP service, I fail to sync successfully from outlook client on MacOS.
[Configuration Info]
InternalConnectionSettings : {myMailServer.fqdn:993:SSL, myMailServer.fqdn:143:TLS}
Status Name DisplayName
Running MSExchangeIMAP4 Microsoft Exchange IMAP4 Running MSExchangeIMAP4BE Microsoft Exchange IMAP4 Backend
[Mail Client Settings] Incoming server: myMailServer.fqdn:993 (Use SSL to connect) Outgoing server: myMailServer.fqdn:587 (Use SSL to connect)
[ECP Receive Connector Configuration] Client Frontend Authentication Settings
- Transport Layer Security - enabled
- Basic Authentication - enabled
- Integrated Windows authentication - enabled
- Exchange Server authentication Permission Groups
- Exchange users - enabled
- Anonymous users - enabled
Scope
- both IPv4 and IPv6 - left defaults unchanged
- port 587 - default unchanged for IPv4 and IPv6
Not quiet sure why the client can connect to the exchange server with the IMAP settings but not sync inbound email or send an email (sitting in outbox). I could not see anything obvious in the event logs or logs in the exchange installation path. Any suggestions you could offer in troubleshooting this would be appreciated.
Best regards - Les
