I know that officially the Dynamics 365 App for Outlook isn't supported by Exchange Server 2019 (https://docs.microsoft.com/en-us/dynamics365/outlook-app/deploy-dynamics-365-app-for-outlook#requirements) by now, but we would like to upgrade the whole Environment at once and are not willing to risk that the App isn't working afterwards.

My question is now:
Has anyone tried the App with Exchange 2019 by now? Are there any Problems or is it working without complications?

Are there generally any difficulties that we should be aware of when upgrading the CRM (current Version or changing the Servers behind?

best regards,
