I've recently setup and exchange 2010 server (with sp1) to replace an SBS 2003 server.
It all seems to work fine apart from Android handsets which cannot connect via active sync. They give an error message saying the username and password are wrong (they aren't). FYI the handsets are Samsung Galaxy's running 2.2.
I was wondering if the fact the server is running a self signed certificate might be a factor? The certificate does not have the external FQDN listed. Is it worth generating another self-signed cert with the external address listed? If so can someone expand on how to do this as I can't seem to find any info anywhere.
