Update 2:00-

The Helpdesk has received alot of calls with people unable to access webmail via various different cell phones. The new Exchange 2010 front end servers were not authenticating properly to the Exchange 2003 mailbox servers via ActiveSync. Janis and I found and fixed this with a hotfix available from Microsoft. Tests on the phones we have available to us (iPhone, Droid) seem to work OK now, but others such as Palm and some Blackberries may still have some issues.

The only other issue we are seeing is with SSL certificates not being trusted, and we are attempting to fix this issue on phones we are familiar with.

We have switched webmail.uis.edu to point to the Exchange 2010 front end
servers. All webmail traffic will now go through Exchange 2010.

There have been reported issues with people off campus not being able to
connect to webmail, and we have found these to usually be DNS related
issues.

Some providers are taking longer to pick up the DNS changes than others.
Also, clearing a machine’s DNS cache is sometimes necessary.
