We have started to migrate our users from on-prem to Office365. The migration provides the end user with a new machine (Windows 10 Anniversay) and Office2016 deployed via SCCM using click to run package. During the initial cache backfill users are not receiving new email, instead they are having to manually request a Send / Receive folder update to receive email on the Exchange server. They are more aware of this problem because the Outlook client on IOS is receiving the new email in a timely fashion.
If the initial syn period is dropped to a few days then the new email appears in the Inbox as expected (even though folders are still backfilling into the cache). Once the cache is completely backfilled Outlook also returns to the expected behaviour. Mailboxes are in the order of several GB and backfill is set to 12 months
Has anyone else experienced this issue? It feels like either the new mail notification is not being received by Outlook to check Exchange Online, the new email is being received but not presented in the client, or some form of throttling is occuring either server side or client side. We have a case open with Microsoft Premier but looking for community experience.

Outlook 2013 and newer have the "fast access" feature that should ensure new messages are displayed and calendar is updated, you can read more about it here: https://technet.microsoft.com/en-us/library/cc179175.aspx
And here are even some more details along with the differnt GPO settings allowing you to properly prepare for such scenarios: https://technet.microsoft.com/en-us/library/cc179067.aspx

@Vasil Michev thanks for the response and links, I would have a closer look at our GPO and the client behaviour. As you say based on "fast access" the expected behaviour should not be what we are observing. Will update with more info after testing
