Could not connect to Microsoft Office Outlook

Posted on by mrioux 140

We have a few users who cannot connect to Outlook through the Navision 2013 RTC. The error message: Unable to cast COM object of Type 'Microsoft .Office.Interop.Outlook.ApplicationClass' to interface type'Microsoft.Office.Interop.Outlook._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{#####}' failed due to the following error: No such interface supported (Exception from HRRESULT: 0x80004002 (E_NOINTERFACE)).

    After investigation I recommended to repair resp, uninstall/install office.

    For my customer this solved the issue.

    Hello

    Repair of office 2010 also worked for our client.  Issue started after uninstalling NAV 2009.  We installed NAV 2013 for testing/go live and the problem started after uninstalling the previous NAV 2009 client.

    Reinstalling NAV 2013 did not work but the office repair fixed the issue.
