Hi everyone,
I am seeing issues with the Graph API method findmeetingtimes.
As you can see from the attached file the API response differs depending on the start time. When using flat times like 12:00 the response includes only flat times - while when using non-flat times like 12:15 it only includes 'half-hour times'.
So to get all possible meeting times I would have to make at least two api calls, which doesn't seem very practical.
Can someone maybe from Microsoft give me some feedback about that behavior ?
Thanks in advance, Jannick

2021-05-25T19:56:55.667+00:00 I see the same behavior and its related to start time being anything that is not :00 or :30 minutes. I have noticed that when the start time is something like 10:15 or 10:45, the slots returned will start from 10:30 and 11:00 respectively leading to the flat times.

2021-05-26T09:34:10.037+00:00 Hi Danstan, yeah it seems to be, that depending on the start time the next free time will determine all following slots. E.g, if the next free time is 12:00 and the duration is one hour all follwing times will be full hour, and if the next free time is xx:30 all following times will be xx:30...

2021-05-26T09:34:50.08+00:00 so the api must be called at least two times...
