I'm trying the query below, Graph Explorer or PowerShell.
https://graph.microsoft.com/beta/teams/{group-id-for-teams}/channels/{channel-id}/messages
The connection is completed successfully and you can get the message.
But I can only get a part.
Looking at it, only the latest data is available.
I would like to know how to get the past amount.
Thank you.

Thank you for the post! I've added the "office-teams-app-dev" tag to this thread since you're using a Teams specific GraphAPI/PS call.- Are you able to provide any examples or screenshots so their team can gain a better understanding of your issue?
If you have any other questions, please let me know.
Thank you for your time and patience. -

（URL）
https://developer.microsoft.com/ja-jp/graph/graph-explorer
（Query）
GET beta https://graph.microsoft.com/beta/teams/{group-id-for-teams}/channels/{channel-id}/messages/I made a successful connection and got results.
However, the results are only partial.
There was a message from 5/8, but I could only get it until 7/31.
Some other teams could only get for September. -

2020-09-30T06:03:36.587+00:00 I tried GET /teams/{id}/channels/{id}/messages/delta.
As the result I have got the oldest data. Thank you!I thought best result what I can get all data.
But I saw following URL and I understood a constraint which Graph API has.
Unfortunately, I will consider another method.
