I was invited to try MS Office 2010 Beta I think back in February, which I did. (I previouly had used both the 2007 and 2003 versions.) Most of the applications work fine--Word, Exel, etc. This was not the case with Outlook, however, which tended to "freeze up" periodically and required re-starts. I could live with that, but then about four days ago Outlook stopped working completely. When I start up Outlook, a box tells me that "there is no email associated with it." (I have/had five email addresses in Outlook, with Hotmail my primary address.) Needless to say, I went to the "File" tab to check my account setups. In the file tab, under information, it says that an upgrade is in progress which may take up to 15 minutes--BUT THAT WAS FOUR DAYS OR SO AGO! It also indicates that I need to upgrade Outlook connector, but when I do it says I already have it. Everything in the "File" tab is essentially "frozen." It won't allow me to check any of the account settings. I have re-booted and re-started dozens of times with no success. I have executed the "repair" function for this application in the Control Panel without success. I would try re-installing, but apparently I can no longer download this beta version. Any suggestions? Otherwise, I believe I will need to uninstall and re-install my 2007 MS Office.
