A customer has an Exchange 2013 SP1 server and a number of Office 2010 and 2013 users. Last week Outlook 2013 began throwing errors when the computers were connected to the LAN. Outlook 2010 can connect to Exchange when the computer is on the LAN or remote. Outlook 2013 can connect to Exchange when remote but not when on the LAN. Error is "Cant open folder"
Have done basic troubleshooting and everything seems to be configured correctly. Customer tells me that nothing has changed recently.
Need assistance diagnosing this further.
Thanks.
