I have a new problem with Outlook 2010 running on Win7Pro. When I click <Reply All>, I get an error message pop up telling me that "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.". If I click <Reply>, then I am able to send a reply without any problems; so I AM connected and Exchange IS working. It just seems to get confused with the Reply All option. Outlook has been working with Reply All until this week. Any ideas greatly appreciated. Thanks.
