Outlook Add-in 10.0.3 inactive in Outlook 2013

AFAIK Outlook 2013 is not supported for Exchange 2007 and it only supports Exchange 2013. In my experience we use EV 10. Please ref. Compatibility

I did some more research into Inactive Add-Ins for Outlook 2013.  I found that in windows registry under

HKCU\Software\Microsoft\Office\Outlook\Addins there was a key entry called EnterpriseVault.DesktopUI.

It had a dword value of LoadBehavior = 2.  Since I had uninstalled the Enterprise Vault Add-In and this key was still there, I removed it.  I then reinstalled the Outlook Add-In. Before I launched Outlook, I checked the registry again.  This key was not there yet.

I launched Outlook and noticed that the Enterprise Vault tab appeared briefly.  Then I received an Outlook message stating that "Outlook detected an add-in problem.  These add-ins decreased performance or caused outlook to crash"  It listed the Enterprise Vault add-in as the culprit with a reason of "Caused Outlook to start slowly" and gave me a button that said "Always enable this add-in"

I decided not to select anything and just close the window.  I looked at Outlook Add-ins under the options menu and Enterprise Vault was listed as a disabled add-in now, which makes sense based on the Outlook warning.  I selected the add-in and selected Enable. When I restarted Outlook, the Enterprise Vault tab was not visible.  I checked outlook addins again and found that it was listed once more under the Inactive Add-ins.  Also, the EnterpriseVault.DesktopUI registry key had now been recreated with the same LoadBehavior value.

Update - I uninstalled the client again and removed the EnterpriseVault.DesktopUI registry key.  I reinstalled the outlook add-in.  When I launched Outlook, I did not receive the warning this time regarding the add-in.  The Enterprise Vault tab has appeared and is functioning well.  I have tried opening and closing outlook a few times, including a computer reboot.  So far, no more problems.

Thanks i didn't looked properly i guess from the Microsoft side i had ref. once

I have been testing with a few more users.  I can't quite narrow the issue down.  Testing with two additional users, one user installed the add-in and has had no problems.  The other user installed the outlook add-in and is having the same problems that I had with Outlook marking the add-in Inactive.  These are all Windows 8 pc's with Office 2013 professional.

I've noticed that with all of the machines that are working, if I go into Outlook and select the File tab, there is a new button in the list below Rules and Alerts called "Slow and Disabled Add-Ins"  When I open it, Enterprise Vault Add-In is always in the list.  It seems like there is a problem with Outlook and what it determines is a problem with the EV Add-in.  

There are significant improvements in the add-in in 10.0.4, including the resolution of a particularly nasty bug that would cause Outlook 2010 to hang while loading that has exisited since 9.0.3. You might want to give it a try.

Is anything else needed on this thread? If not then perhaps mark one or more of the threads that were most helpful as the solution.
