Recently my company disabled SSLv3. Since that time I have been unable to connect to our Exchange 2010 environment from my Windows phone. How can I disable SSLv3 on my phone and force it to use TLS?
I would expect it to just use TLS, you shouldn't have to force it. Usually a client will try different protocols until it finds one that works. You might try this site, the sender test might help confirm your phone can do TLS: TLS Tests and Tools
This site will tell you what ciphers your browser is capable of: https://www.howsmyssl.com/
I would guess the cipher suite for email and IE are the same.
