The problem occurs when I sync a task-list in SharePoint 2010 with Outlook 2007. Outlook asks for authentification, so use my Windows-domain username and password (that same as I use in SharePoint). Everthing works so far, the problem is that SharePoint logs me out at the same time. When I login into SharePoint, Oulooks logs me out and keeps asking for authentification the whole time (and so on)... This is kinda annoying (since Outlook is running the whole time), is there a way to use both, SharePoint and Outlook at the same time?
Note: this ONLY occurs when Outlook is synchronized to SharePoint (in some way).
Hope someone knows something, I keept searching for a possible solution for a few hours by now.
thanks in advance, Markus Schwalbe
