问题
I have removed 4 existing room lists using Remove-DistributionGroup cmdlet.
I have added 1 new room list using New-DistributionGroup cmdlet.
However when calling the API
https://graph.microsoft.com/beta/places/microsoft.graph.roomlist
(using cURL)
with Application Permissions to Places.ReadAll, the API returns the old roomlists and not the new one.
However when calling EWS via EWS Java SDK, the output is as expected i.e. it only shows the new roomlist.
The Office365 Web app also shows the old room lists in the Browse for more rooms option.
Is the places resource returning cached data? If so what is the refresh interval here?
Update (Feb'20) Issue is no longer happening. Changes to roomlists are reflected instantaneously
回答1:
this can take up to 60 hrs to show up in the places API and web app. We are working on making this instant and should have this ready by end of Jan 2020.
