I used Mailenable for over 6 months now and using WACS to create certificates for both my emails and website. after old certificate expired, I used WACS to renew both certificates, website worked perfectly however I got expired certificate error in outlook desktop ( need to accept to receive emails) and all mobile versions was unable to send/receive any new email. checked IIS and noted that both old certificate and new one related to mailenable are existed, even though I selected new one manually, still same issue. tried to delete old certificate from IIS and reselect new one how ever right after getting this error in outlook:
Receiving' reported error (0x800CCC1A) : 'Your server does not support the connection encryption type you have specified. Try changing the encryption method
I did not change any settings mailenable and IIS. webmail is completely accessible and working.
I attached mailenable configs , IIS Cert List, Outlook configs (which was working before) and WACS certificate creation report.
looking forward for any kind advice.
