We have a customer that reports us that they are getting a warning that the mail coming from the NAV server is using TLS 1.0.
I'm unsure whether we should upgrade the NAV server or the SMTP server if that makes sense. And if it is the NAV server, what steps should we give: should it be a NAV build upgrade, and/or .NET upgrade, and/or Windows Register changes?
The NAV version is NAV2013R2 (7.10.42221, CU22)
The NAV server is under .NET Framewok 4.5
Any help would be appreciated.
