Exchange 2013 connection problems on OS X

Hello

I have an Exchange 2013 system with Windows and OS X users, some OS X users sometimes have problems connecting to the server on the local network, in external network have no problems.

Can anybody help me? Thank you.

Of the ones you list, which are the ones that are having issues?  It should be noted that Exchange 2013 requires Outlook 2011 (which you have) or better on the MIcrosoft side.  I'm not sure that OS X 10.7.x Mail software meets the burden on the Apple side.

In short, your 10.7 machines might need to switch to Outlook 2011.  The same might be true for the 10.8.x users.
