I have recently installed a new Exchange 2007 mailserver and a number of users are complaining that the Outlook Web Access keeps freezing and not responding. I have confirmed that the internet connection is constantly up at both ends, and for the most part it is very fast but I have recreated the issue a few times now:
If the screen is open at the inbox for a while I can move from folder to folder without an issue, but once and a while if I select the "Check Messages" button I get an IE7 loading circle then an error saying:
Your network connection is unavailable. Please reconnect and try again. If the problem continues, contact technical support for your organization."
If I refresh the screen a few times it comes back, I can also click on other folders and view the contents of them without issue, but the inbox remains blank until it feels like coming back.
The internet connection is up during this error, and there are no errors apearing in the servers event logs.
Any help would be appreciated.
