Microsoft Outlook disables add-ins that take more than one second to load. In some rare circumstances, our Microsoft Outlook COM add-in may take over one second to load and could be disabled by Microsoft Outlook.
What Is the Fix for This Issue?
From Microsoft Office 2013 and onwards, Microsoft introduced the concept of resiliency keys. These are registry keys that prevent our Outlook add-in from being auto-disabled by Microsoft Outlook.
Option 1: Download the Latest Add-In Version
Ensure that you have downloaded the latest Microsoft Outlook add-in.
All versions of our Outlook add-in, v23.03 and later, automatically add resiliency keys to the user’s registry during a fresh install and during upgrades from previous versions.
Option 2: Manually Update Registry Keys
If, for some reason, your organization is not able to upgrade to v23.03 or later, follow the steps below to add the registry keys to the user’s profile manually:
| Name | Value | String | Location |
|---|---|---|---|
| EgressEmailProtection | 1 | String | [HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook\Resiliency\AddinList] |
| LoadBehavior | 3 | DWORD | [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\EgressEmailProtection] |
| EgressEmailProtection | 1 | DWORD | [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\DoNotDisableAddinList] |
| EgressEmailProtection\dtype | 0 | DWORD | [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\NotificationReminderAddinData] |
| EgressEmailProtection | 967a844d | DWORD | [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\NotificationReminderAddinData] |
If the COM add-in has been previously disabled for this user, then this information is stored in the registry and will prevent admins from re-enabling the Egress Outlook add-in. The following keys need to be deleted:
- [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\DisabledItems]
- [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\CrashingAddinList]
Option 3: Run a Registry key File
We have packaged options 1 and 2 into a registry file. This package can be downloaded here: https://workspace.egresscloud.com/quickshare/uNoM5PnJ. To run it, double-click on this file on a user’s machine. The logged-on user must run this file; otherwise, the registry keys will be applied in the wrong location.
