Is recoverableitemspurges officially supported in Microsoft Graph v1.0?

Hello,

I have a question regarding the support status of the recoverableitemspurges mail folder in Microsoft Graph v1.0.

According to the Microsoft Graph mailFolder documentation, the list of well-known folder names includes recoverableitemsdeletions, but I could not find any mention of recoverableitemspurges.

However, when testing with Graph Explorer, the following request succeeds:

GET https://graph.microsoft.com/v1.0/me/mailFolders/recoverableitemspurges

Response:

{ "displayName": "Purges", "wellKnownName": "recoverableitemspurges", "totalItemCount": 0 }

The following request also succeeds and returns an empty collection rather than an error:

GET https://graph.microsoft.com/v1.0/me/mailFolders/recoverableitemspurges/messages?$top=10

Response:

{ "value": [] }

Based on these results, Microsoft Graph appears to recognize recoverableitemspurges as a valid well-known folder name.

Could Microsoft please clarify the following:

1. Is recoverableitemspurges officially supported in Microsoft Graph v1.0?
2. Is its use covered by backward compatibility guarantees?
3. Is the absence from the mailFolder documentation intentional or a documentation gap?
4. Is accessing messages in the Purges folder a supported scenario for application development?
5. If not, what is the recommended alternative for accessing Purges content?

Thank you.
