Enforce Office Add-ins

This guide will show you how to force add-ins to load in Office every single time. We will also prevent users and office from disabling/enabling add-ins*.

*Outlook 2016* will sometimes disable add-ins any way, but we will apply a workaround for this.

At the end of the guide, the add-ins you configure will look like this:

Getting the ClassID of an add-in

Find the ClassID of the Add-in. This is found in:

• HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins
• HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Office\application name\Addins
• HKEY_CURRENT_USER\Software\WOW6432Node\Microsoft\Office\application name\Addins

It is usually in a format similar to Application.OutAddin

Enforcing add-ins 

We will now create a GPO that will enable or disable the add-ins that we configure.

1. Create a GPO called Office Enforced Add-ins
1. *Depending on the importance(compliance, auditing, etc) of this Add-in it might be a good idea to Enforce the GPO(Right Click > Enforced) . This ensures that it is applies to OUs that have Inheritance Blocked
2. Go to User Configuration\preferences\Windows Settings\Registry
   
3. Create a new Collection Item to group the Add-ins
4. Create a new Registry Item
1. Hive: HKCU
2. Key path: Software\Policies\Microsoft\Office\16.0\Outlook\Resiliency\AddinList
1. (For word addons, use Software\Policies\Microsoft\Office\16.0\Word\Resiliency\AddinList instead)
3. Value Name: Enter the ClassID
4. Value Type: REG_SZ
5. Value Data: Enter the appropriate value
1. 0: The add-on is disabled and your employees can’t change it.
2. 1: The add-on is enabled and your employees can’t change it.
3. 2: The add-on is enabled and your employees can change it.
   
6. Under Common make sure to enable "Remove this item when it is no longer applied"
   
7. Set the item level targeting filter if you are only applying the policy to certain users(members of certain group).
5. Remove add-ins in the Crashing or Disabled List
1. Outlook 2016 will sometimes disable add-ins even if they are enforced. Creating the reg keys below will ensure that they are enabled the next time a user signs in.
2. Clear CrashingAddinList
1. Action: Delete
2. Hive: HKEY_CURRENT_USER
3. Key Path: SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\CrashingAddinList
3. Create CrashingAddinList
1. Action: Create
2. Hive: HKEY_CURRENT_USER
3. Key Path: SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\CrashingAddinList
4. Clear DisabledItems
1. Action Delete
2. Hive: HKEY_CURRENT_USER
3. Key Path: SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\DisabledItems
5. Create DisabledItems
1. Action: Create
2. Hive: HKEY_CURRENT_USER
3. Key Path: SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\DisabledItems
