I am trying to get message from all public channel even from ones which i am not a part of.
I am getting 403 "code": "Forbidden", "message": "UnknownError" error.
I have created an application on https://portal.azure.com/ which is having all the permissions needed for this operation

Hi @Kedar Kekan ,
Before calling this API for fetching channel messages you must request access. For details, see Protected APIs in Microsoft Teams.

I already requested for this and I am able to get messages from public teams and channels which I am part of.
Could you please share the endpoint you are using?
@Sheena-MSFT i am using https://graph.microsoft.com/v1.0/teams/{teamID}/channels/{channelID}/messages/delta?$filter=lastModifiedDateTime+gt+2021-12-01T17:28:19.000z&$top=50 to get messages.

@Sheena-MSFT any update on this? Do you have any idea how can I get required data? Or if I am missing anything here.
