Why does Outlook 2007 not close data files properly and how can this be fixed?

m srinvas May 5, 2011

Three users of Outlook 2007 shut down their computer and the next time they turn them on, they get the error message “A data file did not close properly” in Outlook and Outlook checks its integrity each time. They also get an Event ID 7003, Outlook session terminated unexpectedly.

    Hello, it is either a problem with an add-in or your antivirus/firewall can be interfering. I would try disabling/removing some add-in until you find the culprit. To remove/disable add-ins, you can follow the next steps:

    -- open Outlook
    -- select Tools
    -- select Trust Center
    -- select Add-ins
    -- look and select the manage com add-ins
    -- highlight an add-in and remove
    -- close outlook
    -- restart computer
    -- see if you get the error message
    -- keep disabling/removing add-in until error does not appear anymore

    If you didnt upgraded to SP2 then do it with windows update, this can solve the problem.

    Possible is that some add-in (check HKEY_LOCAL_MACHINESOFTWAREMicrosoft
    OfficeOutlookAddins)or external application is holding Outlook open so that it can't close completely or simply that the user tried to restart Outlook too soon after shutting it down. You can check Task Manager to see if Outlook.exe is still running and try waiting longer.

    for the addons (HKEY_LOCAL_MACHINESOFTWAREMicrosoft
    This will reveal all of the addins that you have loaded onto your system. each of these addons have a parameter named: "LoadBehavior" that usually contains a value of "2" or it may appear as "0x00000002 (2)". double-click the key and make it a "0".

    Try running Outlook with the /safe command-line switch to make sure all add-ins are disabled. Also turn off any anti-virus email checker and any PDA sync utility, so you can troubleshoot this

    If you find the Outlook process is still running then you will need to
    determine just what is keeping it open - synch software, Addins,3rd party
    application ....

    Shutdown Addin (shareware)

    here is list of some of the programs that will keep outlook from closing

    Also run Scanpst.exe to correct any errors
