Our Windows users who connect from home using Verizon DSL have no trouble using OWA to access their e-mail on our Exchange 2007 server. Our Mac users who use Verizon DSL can't even get to the OWA login page no matter which Mac browser they use. Our Mac users who use Verizon FIOS any non-Verizon Internet connection have no trouble at all. Whatever the problem is is, it seems to affect only Macs connected via Verizon DSL. I've verified this with my own Mac and PC laptops. The Mac can't pull up the OWA login window while on my home network, which uses a Verizon DSL connection. The Windows laptop on the same network has no trouble. The Mac laptop has absolutely no trouble using OWA when connected any way EXCEPT via Verizon DSL. Has anyone else run into this problem? If so, has you found a solution? -- Chip Old BCPL Network Operations
