How frequently does the letter 1 appear in:
Q: Exchange 2013 and TLS 1.1/1,2 I have Exchange 2013 on Windows 2012R2 server.  Everything is patched and up to date.
Recently out PCI scanner has required that TLS 1.0 not be used to pass compliance.  So using Qualys IIS Crypto I used the PCI template and unchecked TLS 1.0.  Restart the server.  After restart I can get to OWA just fine.  It shows using TLS 1.2.  However if I login it I get a blank page.  
If I try Outlook 2013 it will not load the profile.  If I try to test the AutoConfiguration I get unable to determine settings.
If I go back recheck TLS 1.0 and reboot, everything works fine again.
Am I missing something?

A: I have engaged Microsoft regarding this issue. Here is their response:

Disabling TLS 1.0 on Exchange is unsupported. Solution is to keep TLS
  1.0 enabled on Exchange Server.
