Really weird SharePoint List ghost in Outlook 2007 / 2010
Like this ticket, but the test site where the calendar lived was deleted 2 years ago.
I have a few Outlook users that are complaining about a pop-up logon window to logon to a local sharepoint 2010 server. I have tried to delete the phantom published calendar but it needs to be deleted from outlook. I have tried to change the behavior.
I'm thinking I need to try deleteing the .ost files and see what happens.
