I'm using the Microsoft Graph API to obtain the actual size and item count for a user's Deleted Items folder. However, the API response seems to include data from the Recoverable Items folder, which causes a discrepancy because no emails appear in the folder when viewed in Outlook or OWA.
Here's the request I'm using:
HTTPGET https://graph.microsoft.com/v1.0/me/mailFolders/deleteditems
The API response returns:
JSON{ "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('4011bbed-71be-429b-a234-1bec4112a689')/mailFolders/$entity", "id": "AQMkAGI1MDYxMzMAZS05MWE0LTQ2M.....3gmMwBACo1omjSnX9HglM9wY_BRqEAAAIBCgAAAA==", "displayName": "Deleted Items", "parentFolderId": "AQMkAGI1MDYxMzMAZS05M....mMwBACo1omjSnX9HglM9wY_BRqEAAAIBCAAAAA==", "childFolderCount": 0, "unreadItemCount": 0, "totalItemCount": 43, "sizeInBytes": 648887, "isHidden": false }
My questions are as follows:
Any guidance would be greatly appreciated. Thank you!

Below is a summary of the current situation and possible workarounds:
At this time, the Microsoft Graph API does not offer a parameter or query method to exclude the Recoverable Items folder when retrieving folder metadata. The response from the API aggregates properties (like total item count and size) that include recoverable items, so you cannot directly get only the visible (user‑accessible) deleted messages via the standard mailFolders endpoint.
Since you cannot exclude the Recoverable Items data from the folder metadata query, consider these approaches:
Query Messages Directly:
Instead of using the folder metadata endpoint, you can list messages in the Deleted Items folder:
HTTPGET https://graph.microsoft.com/v1.0/me/mailFolders/deleteditems/messages
This call will return the messages that are directly visible in the folder. You can then compute the count and possibly the aggregated size (if size metadata is available on each message), giving you a more accurate representation of what the user sees.
Filtering and Aggregation on the Client Side:
If you need more refined control, you might retrieve messages with additional query parameters (for example, filtering out certain message types) and then calculate the size and count yourself. Keep in mind that pagination may be required if the folder contains many messages.
Currently, the Microsoft Graph API does not expose endpoints to query, manage, or clear the Recoverable Items folder. This folder is a special system folder (often used for retention and recovery purposes) and is not directly manageable via Graph. To interact with the Recoverable Items folder, you may have to use other interfaces such as Exchange Web Services (EWS) or PowerShell cmdlets provided by Exchange or Office 365 administration tools.
.../mailFolders/deleteditems/messages) to derive the actual count and size manually.This approach should help you narrow down the visible items from the folder itself while working around the inclusion of recoverable items in the folder metadata.

However, when I check the Deleted Items folder in the user's mailbox (via Outlook or OWA), there are no emails in the folder. This discrepancy seems to be caused by the Recoverable Items folder, which is likely affecting the size and item count of the Deleted Items folder in the Graph API response.
Yes, The discrepancy between the sizeInbytes and totalItemCount is caused by the Recoverable Items folder being part of the Deleted Items metadata. The Deleted Items folder is affected by items that may have been moved to the Recoverable Items folder.
As of now, Unfortunately, there is no direct way to exclude the Recoverable Items folder when retrieving the size and item count of the Deleted Items folder via the Graph API. So, you need to query them separately by querying deleted item and Recoverable items.
Note: recoverableitemsdeletions contains soft-deleted items: deleted either from the Deleted Items folder, or by pressing shift+delete in Outlook. Refer this MsDoc.
To list the deleted items from Delete Folder of mailbox:
HTTPGET https://graph.microsoft.com/v1.0/me/mailFolders/deletedItems
To list the deleted items from Delete Folder with messages of mailbox:
HTTPGET https://graph.microsoft.com/v1.0/me/mailFolders/deletedItems/messages?$filter=parentFolderId eq 'deletedItems'&$count=true
To list the RecoverableItemsDeletion folder of Mailbox:
HTTPGET https://graph.microsoft.com/v1.0/me/mailFolders/recoverableitemsdeletions
To list the RecoverableItemsDeletion folder with messages of mailbox:
