Comments
If your Microsoft Tenant uses Intune, like my tenant does, you will not see the option for Microsoft 365 installation options under Settings > Org settings > Services >. You obviously need to deploy this app via Intune to your client computers. I have also just discovered that .XML manifests cannot be natively distributed via Intune. Therefore, Mimecast can we please have an MSI to distribute via Intune?
Hi Chris,
Thank you for your feedback. Here is some information that may explain the issue you are experiencing and how to resolve it:
Outlook add-ins aren't deployed to computers through Intune; they are deployed through Exchange. If you don't see the option for Integrated Applications in the M365 Admin Center, you may not have the correct administrator role to complete the install. A Global Administrator, or one of the roles described in this Microsoft KB Article can access the Integrated Apps Portal to deploy the MPP app.
Outlook add-ins are required to be in XML format to deploy through Exchange. You cannot deploy an Outlook add-in through Intune.
I hope this helps. If not, please take a look at the following article on raising a Support Case to get further assistance: https://mimecastsupport.zendesk.com/hc/en-us/articles/34000342907923-Mimecast-Customer-Care-Raising-a-Case
