I am trying to get my Outlook 2010 to sync calendars with my internet calendar. When I attempt to open the program I am getting an error message that says "The selected Microsoft Outlook profile does not exist. You have to re-configure." then I close that window and this error comes up: "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client". I do not have a POP3 account so I cannot set up the mail client in Outlook and cannot get this never ending loop I am stuck in to stop. I have tried to remove Outlook and the associated data files. Re-installed Outlook in hopes of getting the set-up to run again so I can set a Profile but NO LUCK! Can someone help me? I want to delete everything from this software and start new but I do not want to RE-format the computer.
