Outlook 2019 Online Mode Results In No New Email Notifications

Alex Fogerty 66 Reputation points

Hi guys,

I have a client who needs to use Outlook 2019 in non-cached mode (a.k.a. exchange online mode), but for some reason they don't get new email notifications in Outlook or Windows 10. When I change Outlook to Cached Mode the new email notifications work again. Seems like an Office 2019 bug, but I'm wondering if anyone knows of a work around?

    Hi @Alex Fogerty ,

    Creating and enabling an Outlook rule like below in your Outlook desktop client should be able to bring New Email Notifications back:


    • Home > Move > Rules > Manage Rules & Alerts > New Rule
    • Select Apply rule on messages I receive
    • Select no conditions to make rules work on all incoming email messages
    • Select Display a desktop alert in Actions
    • Click Finish

    Hope this can be helpful.
