Where did my Prophet tab go? Prophet Tab Missing.


The Prophet tab is missing from the top of Outlook.


If the Prophet tab is visible, but most of the selections are disabled, that's because one of Prophet's folders is selected.  Most features of the Prophet tab aren't needed when the Prophet Folders are selected, and thus only Settings, Analytics` and Search are enabled.

Solution 1 - Configuration file

Close Outlook.

Click Windows Start button and paste in this path and filename, and press Enter.

C:\Program Files\Avidian Technologies\Prophet\ConfigureProphetClient.exe

Click 'OK' on the prompt that appears

Reopen Outlook and test.

Solution 2 - Always Enable

Verify Outlook didn't change it to 'Inactive'

In Outlook, click the File tab.  Click the "Manage COM Add-ins button.  If you co not have this button, skip to the next steps.

Click the Options dropdown arrow or click "Always enable this add-in" (older Outlook)

Click Enable and Apply, or Always enable

Set the option to "Do not monitor this add-in for the next 30 days" and click Apply.

Solution 3 - Manage Add-ins

In Outlook, Click > File > Options.

In the 'Outlook Options' window that opens up, click 'Add-ins' on the left hand side

If Avidian Prophet, AvtAddin2010, or Avidian Prophet Ribbon are in the Inactive section, click the Go button.  

Check the boxes for Avidian Prophet, AvtAddin2010 or Avidian Prohpet Ribbon, and click OK.

If any of Prophet's Addins are in the "Disabled Application Add-ins" section, change the choice left of the Go button to Disabled Items and click Go.

Select each line of any Prophet Add-ins and click Enable and click Close.

Change the selection back to COM Add-ins, click Go and check the boxes for any Prophet Add-ins.

Restart Outlook and check if the Prophet tab is restored.

Solution 4 - Run Its Installation File

If the above steps didn't work, we'll run the installation for the Prophet tab.

Run these two files.

C:\Program Files\Avidian Technologies\Prophet\AvtAddin2010.vsto

It is the last one alphabetically and has the Type of VSTO Deployment Manifest.

C:\Program Files\Avidian Technologies\Prophet\ConfigureProphetClient.exe

Restart Outlook.

Solution 5 - Reinstall Microsoft's VSTO Runtime

If the above steps didn't work, we'll Reinstall Microsoft's VSTO Runtime.

Here's the installation for Microsoft's Visual Studio Tools for Office Runtime (VSTO). It's a standard part of an Office installation, but we sometimes find that it needs to be reinstalled.  

Once that is installed, please run the files in Solution 4 again.
