Hi @Sven van Meurs ,
Will archived calender items be available in the "new" Outlook-app?
As you may have already noticed, this is currently not yet supported in the New Outlook preview. Then I tried searching a lot but so far haven't seen it mentioned in any official document about the plan to add this feature in the New Outlook. There's no relevant item available in the Microsoft 365 Roadmap either.
Given this, I've just tried sending this suggestion via the in-app Feedback option:
And I've also submitted this into the official feedback portal for Outlook. I'll leave the link below in case you or other community users who see this thread would like to vote it up or comment there. Hope this feature can be added soon!
