EmailMerge365 for Microsoft 365 can be installed or deployed centrally via the Microsoft 365 Admin Center. However, that it may take several hours for the add-in to appear for all users—this delay is controlled by Microsoft.

Admin installation (Microsoft Admin Center)

  1. Click here to Launch the add-in deployment wizard directly in your Microsoft 365 admin center (Integrated apps). If necessary, sign in to Microsoft with your organization’s Microsoft 365 global admin account.
  2. In the wizard, EmailMerge365 will be listed and automatically selected. Click Next.
  3. On the next page of the wizard, you’ll see the Assign Users options:
    • Entire organization
    • Specific users/groups
    • Just me

    Select the appropriate option. If you’re using Specific users/groups, you can search for users in the text field.
    Note: For testing purposes, do not select “Entire organization”. We recommend deploying the add-in to a few users using the Specific users/groups option.

  4. Click Next. The App permissions and capabilities page will appear. 
  5. After accepting permissions, click Next to proceed to the Review and Finish Deployment page.
  6. Click Finish deployment.
