Limitations & out-of-scope
Channel.ReadBasic.All and Team.ReadBasic.All return metadata, not message content, so this is a storage-consumption report, not a content audit — it cannot tell you what was stored, only how much. Because private-channel files live in a separate SharePoint site per channel, very large teams with many private channels take proportionally longer to enumerate and are more exposed to Graph throttling than a team with only a main channel.
