To help answer some of those questions, we’ve launched a Mobility Solutions page on the Microsoft Online Servicesen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.technet.com/msonline/archive/2009/07/07/going-mobile-with-microsoft-online-services.aspx#3264147Wed, 15 Jul 2009 01:59:53 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3264147DavidDsh<p>The Online Services is fantastic and works extremely well for laptop and desktop, but I really need more info on how the install the Sign-on application on a mobile device. I wish to access a Sharepoint site I have created and all attempts to do so from a mobile device have failed. I am using a HP Ipaq which has no trouble accessing another hosted Sharepoint site I use. The links provided here are very good but I cannot find out about the sign-on application.</p> http://blogs.technet.com/msonline/archive/2009/07/07/going-mobile-with-microsoft-online-services.aspx#3265414Thu, 16 Jul 2009 23:01:11 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3265414kunapalli<p>The sign in client does not work on a mobile phone. However, other than the combination of windows mobile + IE, customers should be able to use activesync enabled phones for email and to access sharepoint without a sign in client. The authentication for SP on a mobile phone will roll over from cert auth to basic auth. </p>
