Outlook Project Add-In Crashing


  • I am currently experiencing an issue with the project add-in for outlook.


    Currently I am running:

    Windows Vista 32 bit Business Edition

    Office 2007

    All the latest service packs and updates


    Recently I have setup Project Server 2007 and want to use the project add-in functionality.  Everything had been working fine.  I had upgraded Sharepoint and Project Server to the latest service packs to resolve a few issues.  The add-in was functioning correctly after the service pack install.


    Then all of a sudden the add-in crashed with the following error message:


    An unexpected error has occured.

    'Please reload the Project Add-in for Outlook by clicking the Trust Center on the Tools menu.  From there, clikc Add-ins, and then Go under Manage COM Add-ins.  On the COM Add-ins dialog, ensure that Microsoft Office Project Server 2007 Add-In for Outlook is checked, and then click OK. If this does not resolve the issue. you may need to repair or reinstall the add-in via Add or Remove Programs from the Control Panel.'


    So naturally I did what was suggest of the error message:

    I reloaded the Add-In within the Trust Center (error still occurred)
    I removed the Add-In via Add/Remove programs and then reinstalled (error still occurred)
    I turned DEP off and tested (error still occurred)
    When checking the application event logs the following event appeared:


    Log Name:      Application

    Source:        MS Project - Outlook Integration

    Date:          6/02/2008 9:32:14 PM

    Event ID:      1

    Task Category: None

    Level:         Error

    Keywords:      Classic

    User:          N/A

    Computer:      <computer-name>


    The description for Event ID 1 from source MS Project - Outlook Integration cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.


    If the event originated on another computer, the display information had to be saved with the event.


    The following information was included with the event:




    Component:  OutlookTalker.cls

    Procedure:  UpdateProjectBasedOutlookItem

    Error Number:  91

    Error Source: MPSInt12

    Error Description:  Object variable or With block variable not set



    Event Xml:

    <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">


        <Provider Name="MS Project - Outlook Integration" />

        <EventID Qualifiers="0">1</EventID>




        <TimeCreated SystemTime="2008-02-06T10:32:14.000Z" />

    Component:  OutlookTalker.cls

    Procedure:  UpdateProjectBasedOutlookItem

    Error Number:  91

    Error Source: MPSInt12

    Error Description:  Object variable or With block variable not set






    I have removed and reinstalled this add-in many times, but it does not resolve the issue.  Looking at the updates Service Pack 1 nothing has changed in regards to the project add-in.  Currently I have 15 people using the add-in (mixture of winxp and winvista all using Outlook 2007) and this error has only occured on a single machine.


    Any help would be mostly appreciated.
    Thank-you in advanced

  • I have been struggling with this for a while and everything I tried did not work and I am running pretty much the same platform as you.


    I have changed some settings and it now seems to work but I'm still not sure of the exact cause of the problem.


    What I did was....


    1. Went to Outlook Tools>Options> and the Project Web Access tab.
    2. I then changed the Assignment Import > Date Range: to Next 2 weeks instead of the Project Web Access Date Range.
    3. The other settings are Integrate with Outlook Tasks and everything else is set to manual.

    I know this does not solve the actual problem but it does allow you to actually use the project add in for Outlook while we wait for a fix....


    Hope this helps!

  • I also had the same problem. The thing that solved it for me was to change "Standarts and Formats" setting in Regional options to English (United States). After that the error dissapeared and I had no problems updating.

  • Where do you make this change? This Project error is driving me bananas.

    Where do I find the Standards and Format and Regional Options?

    Help is greatly appreciated

    For me it worked by completly deleting the tasks that came from PS2007 and re-importing.

    Guess this was the easiest way to fix it.


    All the best,

  • Gurantee this will fix all you big heads issues...

    1) Uninstall the Project Add-in for Outlook in Add/Remove Programs
    2) Open outlook, go to >Tools> Options. From the Options Menu, select the
    >Other>tab. On the >Other>tab under the>General> sub-header, click
    >Advanced Options> From within>Advance Options> click >Custom Forms> this will open-up an additional >Options> menu. Click >Manage Forms>On the right-hand side, remove all referances to Project Web Access. Apply changes and close sub-menus.
    3) In outlook, go to tasks. Remove all tasks (Active and Closed) that were
    downloaded from the Project Web server. Close Outlook.
    4) Go to >Start>, >Run>Type in >œregedit>
    , click OK. Open
    >HKEY_Current_User>Software>Microsoft>Office>, >Outlook>Addins>.
    Delete the >ProjectServer.12> folder under >Addins>Close the Registry
    5) Reboot the machine Once the system is back-up reinstall the Project Add-in for Outlook; once it is installed reboot the machine again (even though you will not be prompted to do so).  On the system is up again, will need to re-configure the Project web add-in. You should now be able to import your tasks.

    Shift the Ctrl in our hands and we will Alt the world.
