How to Install Addons in Outlook and Office 365

Many third-party integrations have been restricted in the Office 365 environment unless they are administratively managed by JMU's IT Department. If you are attempting to install an add-in from the Microsoft Marketplace, you may receive an error message:

  1. In Outlook on the web, if you try to add a third-party add-in, you will only see a blank screen. 
  2. In the add-ins marketplace within the Outlook Clients, if you try to install an add-in from the All tab you will receive an error

 

You can, however, install an add-in from the Admin-managed tab. Currently, Zoom, Teams, and Salesforce are the only non-default add-ins available here. Other add-ins will be evaluated on a case-by-case basis by Information Technology.

Note: Due to a change on 10/12/2024 required by Microsoft to update requirements for Multfactor Authentication, it is possible that addons with pre-existing connections may need to be re-connected, or will need to be re-evaluated through the TSR process outlined below. Additional information on the recent update can be found here.

There are many cases where previously, addons were allowed to connect  and integrate with the Microsoft Office products (Calendly, Acuity, etc.) and are still active today. However, when attempting to re-connect them with a new computer, after a computer has been re-imaged, or a change being made to JMU's services and/or Microsoft's licensing will display an error that show that those addons are now unable to connect without "Admin Approval." This is due to changes in the licensing of Microsoft Products, and how JMU Manages addons.  

If a piece of software is still needed, it is recommended to submit a Technology Solution Request through the JMU IT Portal. Additional information on Technology Service Requests and how to submit those requests can be found here.
