Specify the administrators and users who can install and manage add-ins for Outlook
You can specify which administrators in your organization have permissions to install and manage add-ins for Outlook. You can also specify which users in your organization have permission to install and manage add-ins for their own use.
This is done by assigning or removing management roles specific to add-ins. There are five built-in roles you can use.
Org Marketplace Apps: Enables an administrator to install and manage add-ins that are available from the Office Store for their organization.
Org Custom Apps: Enables an administrator to install and manage custom add-ins for their organization.
By default, all administrators who are in the Organization Management role group have both of the above administrative roles enabled.
My Marketplace Apps: Enables a user to install and manage Office Store add-ins for their own use.
My Custom Apps: Enables a user to install and manage custom add-ins for their own use.
My ReadWriteMailbox Apps: Enables a user to install and manage add-ins that request the
ReadWriteMailboxpermission level in their manifest.
By default, all end users have all of the above user roles enabled.
If you are testing Outlook add-ins and none are showing up, then as a first troubleshooting step, use the Get-OrganizationConfig PowerShell cmdlet to query the AppsForOfficeEnabled parameter. If the query returns a value of False, set this parameter to True using the Set-OrganizationConfig cmdlet and then add-ins should appear as expected.
We do not recommend that the AppsForOfficeEnabled parameter be set to False. A value of False will override all of the above Administrative and User role settings and prevent any new apps from being activated by any user in the organization.
For information about add-ins, see Add-ins for Outlook.
What do you need to know before you begin?
Estimated time to complete: 5 minutes.
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Role assignments" entry in the Feature permissions in Exchange Online topic.
Access to the Office Store isn't supported for mailboxes or organizations in specific regions. If you don't see Add from the Office Store as an option in the Exchange admin center under Organization > Add-ins > New , you may be able to install an add-in for Outlook from a URL or file location. For more information, contact your service provider.
For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts for the Exchange admin center.

How do you know this worked?
To verify that you've successfully assigned permissions for a user, replace <Role Name> with the name of the role to verify, and run the following command in Exchange Online PowerShell:
Get-ManagementRoleAssignment -Role "<Role Name>" -GetEffectiveUsers
This example shows you how to verify whom you've assigned permissions to install add-ins from the Office Store for the organization.
Get-ManagementRoleAssignment -Role "Org Marketplace Apps" -GetEffectiveUsers
In the results, review the entries in the Effective Users column.
For detailed syntax and parameter information, see Get-ManagementRoleAssignment.
