Turn off SSL on POP 3 connector in Exchange 2010

Posted on 2012-03-13
Last Modified: 2012-08-13
Due to a requirement of a special program used at this one client, I need to turn off the SSL component of the POP 3 connector on Exchange 2010.

This program pops mail off the server tracking diary entries, and doesn't work with SSL.

Is this possible? And if so, how do I go about doing it?

Thanks for that. I assume TLS and SSL are 'the same thing' in this case?

TLS is a replacement system for SSL and has more stringent security, but they're effectively the same.

TLS is effectively SSL v2.0 It is a more secure replacement for SSL.

Mikey, TLS is more correctly SSL v4.0. There have been three different versions of SSL and while the differences between TLS and SSL v2.0 are very minor (specifically, they use different Hashing algorithms and stronger keys), stating that TLS *is effectively* SSL v2.0 is very inaccurate. has some more specific information on the difference between the two. TLS and SSL are functionally the same, but TLS is much more secure.

Agreed, my apologies. However I did use the qualifier "is effectively".
