On my windows 7 machine I have Outlook 2010 and conference add-in installed. Problem is that I keep getting a Windows Security prompt, the server "lm.microsoftonline.com" requires a username and password, even if I'm not accessing it. The popup just comes up every few minutes. Anyone seen this prompt? Outlook works fine, any ideas? Thanks...

Hi, Whether the connection of the Outlook is connected? I assume that this issue is caused by you have not set up the email account properly. Please check it again. Also, because your issue is related to Office and this forum focuses on Windows 7, so I suggest to post the thread at http://social.technet.microsoft.com/Forums/en-us/category/officeitpro,visio2010,grooveserveritpro for help in the meantime.
