Hi all I have outlook 2007, exchange 2007 and sharepoint 2007 installed on windows 2003 sp2. I configure two profiles on client machine. In the first time of entering each profile, I input username and password. "Save password" checked. Then press "OK". But after switching to the other profile, outlook consistently ask me to input username and password. Usually, I cannot enter outlook before after 4-5 times input. Thanks superZZ

There have been a lot of questions recently regarding Outlook prompting for a username and password whilst using Exchange 2007 Please make sure Exchange 2007 Latest Service Pack 2/3 is installed on the server Please refer this "demazter" article for more information http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2300-Outlook-continually-prompting-for-username-and-password.html If that doesn't work check the authentication methods as per "demazter" blog here: http://demazter.wordpress.com/2010/11/09/outlook-prompting-for-username-and-password-when-using-exchange-2010/ Hope this helps.Viral R MCTS

Hi zlfcn: If you want to switch other profile, outlook will ask you input your password. It is design. But why do you want to input password 4~5 times? Do you input different password or same password ? This article is about multiple profiles for outlook. You should check your configuration. You should also check your network (firewall) and update version of outlook and exchange.
