Hello,
we've been using SharePoint 2010 for 1 month now without any major issues. We connect our task and calendar folders to Outlook, and everything used to work fine. But now, everyone has new problem. I open any list, say tasks, in SharePoint 2010, and press Connect to Outlook. Outlook starts, asks questions, and then opens SharePoint folder just fine. However, next tries to update the folder, fail with this error message:
Task 'SharePoint' reported error (0x80040102) : 'Outlook cannot connect to the SharePoint List (Internal Tasks). The server may not be reachable from your location. Contact the SharePoint site administrator for more information. HTTP 405.'
what is going on here?
strangest thing is, looking at IIS logs, outlook doesn't even seem to attempt any operations..
