How to Troubleshoot Outlook Add-in Issues

While it is recommended to deploy or force the changes through the registry, you can do so through the settings on older version of Outlook as well:

Outlook 2003

  1. Click on the “Help” menu in Outlook and then click on About Microsoft Office Outlook.  On the bottom right-hand side, you should see a button labeled Disabled Items.

  3. Restart Outlook.  The add-in should now show.


Outlook 2007

  1. Click the Tools menu and select Trust Center…
  2. In the Trust Center window select the Add-ins menu on the left.
  3. If EIOBoard is listed as disabled, click the Go… button next to the “Manage COM Add-ins” drop-down list at the bottom of the screen.
  4. On the COM Add-Ins screen check any instance of EIOBoard in the list, then click OK.
  5. Restart Outlook.  The add-in should now show.


Outlook 2010

  1. Open File –> Options
  2. Select Add-Ins from the left pane.
  3. If the EIOBoard Outlook Addin 2010 appears on the Inactive Application Add-ins list, select COM Add-ins in the Manage drop-down list. If it shows under Disabled Application Add-ins, select Disabled Items from the Manage drop-down.
  4. Click ‘Go…’.

Office 365

The O365 Version of Outlook, or Click-to-Run Version, may

not respond to the Add-In resiliency from a Registry Key. Many Office 365 subscriptions allow you to install the Desktop (Full) Version of Outlook.

The best option is to install the desktop version of Outlook and maintain the Add-In resiliency locally. Otherwise, you are forced to click: ” Do not check this Add-in for 30 days” every month.

To find out if you can download a full version:

  1. Uninstall the EIOBoard Outlook Add-In (from Settings –> Apps)
  2. Sign into your O365 account: https://portal.office.com/
  3. Click the Install Office Apps link
  4. Install the Full Version of Outlook
  5. Install the EIOBoard Outlook Add-In

After installing the EIOBoard Add-In, apply the “Always Load” behavior mentioned above. This will resolve the issue.
