We just configured our TMG 2010 servers (with Basic authentication) to connect with our new Exchange 2013 server and are finding some devices just cannot connect and others are sporadically having some connections problems but then they can connect.
We have done the following:
- Had users remove and re-add their Active Sync account on their device
- Removed the mobile device partnership on the user's exchange account
- Had them try to connect through the MS Remote connectivity Analyzer (successful)
Has anyone seen this issue?
Any suggestions to correct (would like to avoid setting no authentication required on TMG) if possible?
