Hi!
I am receiving the error "A call to SSPI failed, see inner exception." when using SSL to connect to the mail server:
Connecting without SSL works fine. I have found this, but since that's rather old I wonder if there isn't another problem. Also I hesitate to implement a workaround that would affect a lot more than just this connection.
The mail servers are Exchange 2016 on Server 2012R2 behind a NetScaler load balancer.
Any ideas?
Regards
Erik
