Here is the environment.
We just recently made the switch from On-site exchange to Exchange Online. In the process we had to go through and setup everyone's Outlook accounts, phones, etc..
We have a terminal server that remote people use to interact with our MRP/ERP system as well as use Outlook, Word, Excel, etc...
Outlook will no longer talk to the Exchange Online server. When setting up a user it receieves all of the server information through autodiscovery however when it gets to "Log on to server" a warning box comes up and states:
"Outlook cannont log on. Verfiy you are connected to the network..."
I have installed Office 2007 SP3 as well as the Sign-in Assistant but that doesn't seem to work.
I have also checked our firewall and there are no connections being blocked to the terminal server.
Any suggestions to troubleshoot or at least see where this issue lies?
