    Emails are suddenly not working from our 3CX server. They had worked in version 14 and now version 15, but recently I noticed they stopped coming, and I can't send email invites to new users.

    The error I'm getting is:

    Like I said, none of those settings have changed, and it did work in the past.

    You do not mention the mail server and hosted or on site.
    If a hosted solution of any sort - it is possible they changed their requirements for relaying mail.

    Yep, sorry. On premise Exchange 2007 that I'm in charge of. I haven't changed anything.

    Are you certain your Exchange Certificate is still valid?

    The error does mention an invalid certificate (as you are attempting to use SSL).

    Does it fail on non-ssl relay?
