I have an SBS 2003 running Exchange 2003 SP2. &nbsp;We use Outlook Web Access, RPC over HTTP(s) plus several users have phones that sync up with Exchange. &nbsp;We have a certificate that we purchased through GoDaddy. &nbsp;Things seem to work OK most of the time, except some of the Verizon / ActiveSync phones will not connect on occasion. &nbsp;For example, one day or sometimes two days in a week, the phone will not get any updates. &nbsp;Then it will work fine for several days. &nbsp;We used to think it was the weekend, but it doesn't always stick to that. &nbsp;I've had a hard time tracking down specific error messages on the server. &nbsp;On the phone, it says that the Server could not be reached which may be caused by temporary network conditions. &nbsp;Error 0x85002003. &nbsp;Blackberry phones don't seem to have this problem at all. &nbsp;They do re-verify their credentials, but always seem to be able to sync. &nbsp;Any ideas??

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
