We are running Mcafee SAAS to secure our exchange 2010 communications. Recently we switched from TLS 1.0 to TLS 1.2 and ever since then several of our applications which do batch mailouts of reports have been taking a long time to email.
As far as know no other changes have occurred in the network.
How would I go about troubleshooting this from the exchange end?
Any assistance is appreciated.
