Finally migrating from SBS - which is essentially Exchange 2010 and Server 2008R2.
My plan is to migrate the mailboxes using Sync Jobs, and then switch over. However, I’m struggling with getting the sync job to work.
Err 1/1: Host1 failure: Can not go to tls encryption on host1 [192.168.1.3]: Unable to start TLS: SSL connect attempt failed error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol
I am assuming that the root cause is because Ex2010 uses TLS1.0 and some other retired version of SSL.
I’ve edited the Dovecot.conf file to remove the minimum TLS requirement, but I still cannot connect.
- both to “ssl_min_protocol = TLSv1” and “# ssl_min_protocol”.
I’ve spent many a late night trying combinations of ports, protocols etc.. on both sides, but I can’t get past this error.
Any suggestions would be very welcome! - whether to debug further or to resolve …
