I received an error message when checking my email "Server does not support TSL Connections." what does this mean?
This error will occur when a new security certificate has been installed on the server and you have the old security certificate still setup in your email client.
This can happen from time to time while we stay on top of security.
To correct this you will just need to remove the old security certificate from your email client then install the new one.
As an alternative you may disable it in your email client.
