Scenario: A user initiates the installation of the Lightweight Outlook App in Dynamics CRM 2016, and it never finishes installing.
If your Outlook App installation seems stuck after several hours or multiple days, the solution is to test and enable the mailbox for server side synchronization. After re-running the Test and Enable process, the lightweight Outlook App should successfully complete installation and be available to use from Outlook and OWA.
Can you use this app with a hybrid server environment? We are currently using server side sync in a hybrid setup, and have created our own hybrid server profile in order to accomplish this. The syncing works fine but the app never downloads fully.
No–it works with CRM Online/Exchange Online or CRM On Premises/Exchange On Premises
