I have tried this with lync running and after exiting lync, but the behavior is the same. These entries are created under a different registry key for each message class that the form region supports. I thought that I might disable the Lync add ins to see if outlook would begin functioning correctly again, but as soon as I go into manage add ons, and uncheck the box for 'office meeting add-in for Microsoft Lync 2010' or click remove, outlook locks up. LoadBehavior value changes to 2, and remains at 2 after the application closes Registry Entries for Outlook Form RegionsĬreate a custom form region in an add-in for Outlook, additional registry entries are used to register the form region with Outlook. If an error occurs when loading the add-in, the Load at startup, application successfully loads the add-in, the " Description"="Email - Outlook add-in created with " Manifest"="C:\\Program Files\\YOU_FOLDER\\Email\\Email.vsto|vstolocal " Settings\Email\Create\Software\Microsoft\Office\Outlook\Addins\Email ] [ HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\User HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\User Settings\Email ] This registry setting determines how the add-in is loaded in the application. If you have tried the solution referenced above and the add-in is still not loading when the application is opened, then it may be due to a registry setting.

But even if you upgrade successfully from ePO, the Extend.Dat file may still list the old add-on which still needs to be removed.
Yes, a MID version can be constructed to install VSE without the email scanner Add-on. As Sk1dMARK suggested, unchecking that box, will disable the currently installed add-in, but Extend.dat may not be up to date with that change. Note that this command deletes Extend.Dat from multiple user (profile) directories to which the logged in user has sufficient rights.ĮPO can be used to upgrade VSE. In order to clean up multiple users (profiles) I use a command like this: del /f /s /q "%UserProfile%\.\Extend.dat" This could also be added to a Login Script. After the VSE setup is run, I follow up with the deletion of Extend.Dat. I usually install VSE as part of a batch file. To that end, I have successfully deleted the Extend.Dat file as part of the 'upgrade' process. Unfortunately, Outlook cannot be running when the deletion is attempted as Extend.dat may be locked. Now, Extend.dat is in-sync with the actual add-ins installed. Outlook rebuilds Extend.dat by using the correct list of Add-ins listed in the registry. Extend.Dat is automatically rebuilt the next time Outlook is launched. In reality, Extend.Dat needs to be deleted. At that time or sometimes a bit later, Outlook may complain that the Outlook is not working correctly and incorrectly suggest that Outlook needs to be rebuilt.
Outlook uses the info in Extend.dat in preference to the info listed in the registry without a check for correctness. However, after removing or changing an add-in, the Extend.Dat file may not be in-sync with the information in the registry. To turn add-ins off, uncheck any add-ins you don’t want to load. I have used like forever the same settings and for no reason yesterday when I tried to use my outlook I got this error message pim sync network error, I have asked some friends and they told me.
The improvement is suppose to be faster than reading the registry for the same information. In the Manage area at the bottom of the window, select COM add-ins, then select Go. It's purpose is to increase performance of Outlook during the launch process. Outlook stores the 'add-ins' in a cache file called Extend.dat locally. Sk1dMARK's reply will help greatly, but you may still have an error message at the client side due to the design flaw (in my humble opinion) built into Outlook (Extend.Dat). I think that should work via the policy you can see in my attachment. I want to disable the Outlook Scan Addin global in my company.
