Outlook flashes / flickers after clikcing Open Task button from a SharePoint workflow email notification

Question

I have developed a custom workflow in SharePoint Designer 2010. The workflow runs as expected. I receive the email notification that a task has been assigned to me and the email asks me to click the Open this task button. When I click that button, Outlook starts flashing / flickering. I have to either press Escape or end the Outlook process to get the flickering to stop. I am able to reproduce this exact scenario on multiple computers (Windows 7 Office 2010). I tried the same process through OWA and the button works fine. I have read to edit the formserver.aspx in the 14 bin on the SharePoint server, but that file does not exist in my environment. Does anyone have any suggestions?

Answer 1

I have been searching for a solution for a while. I tried this:

1. click Start–>Run–> Type Regedit and hit enter
2. Regeditor comes up
3. Then navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}
4. Delete the key (looks like a folder) that is named {00000000-0000-0000-0000-000000000000}
5. Then restart Outlook

but I did not find the {00000000-0000-0000-0000-000000000000} folder. I have a 64-bit pc, so instead i tried this:

1. Click Start->Run->Type C:\Windows\SysWOW64\regedt32.exe
2. Then navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}
3. Delete the key (looks like a folder) that is named {00000000-0000-0000-0000-000000000000}

4. Then restart Outlook

   This worked for me. Finally the Open this task button works in Outlook!!!!
