How to reinstall the Dynamics 365 Outlook App After Removing It

Hi,

Recently I was testing the Outlook App. One of my tests was to remove it completely. To do that, I opened the settings in Office 365, clicked “Mail” at the bottom, then expanded “General” and clicked “ManageĀ  add-ins”. This opens this page:

https://outlook.office.com/owa/?path=/options/manageapps

Note: this is the same page that is reached when you open the Outlook Client (2016 for example) and click File and Manage add-ins.
Note: this is different from clicking Options in Office 365 then clicking directly the “Manage add-ins” on the right. This opens the market place. You can see the Dynamics 365 add-in there by clicking “My add-ins”.

From there, you have 2 options:

  • Uncheck the “Turned on” box. That is easy to reset.
  • Click the Minus “-” button. This will remove the add-in completely (as will the Uninstall button from the “My add-ins” page mentioned above).

Now, from there, the question arises: how to reinstall the add-in? The problem is that in CRM, in the settings related to the Outlook App, the user will still show as “Added to Outlook”. You can always click the button “ADD APP FOR ALL ELIGIBLE USERS” again and again, it will not reinstall the app… I tried to deactivate/reactivate the mailbox, and other things, nothing worked.

So… The answer was finally quite simple! In Dynamics, click the gear button on the top right. There, click on “Apps for Dynamics 365”.

Notice under “Microsoft Dynamics 365 App for Outlook”, the green checkbox “Already added to your Outlook”, and next to it the link “Re-add the app”. How beautiful is that link! You need to click it. It will re-add the app to all the eligible users who removed it.
