Microsoft graph API：查询以使用用户 ID 获取已在邮箱上为特定用户创建的订阅列表

Question

Is there any way to get list of subscriptions specific to a users mailbox like we have one for user's one-drive similar to the code below.

The is one end point available to fetch out all the subscriptions as https://graph.microsoft.com/v1.0/subscriptions but I want to get only mailbox specific subscriptions.

IDriveItemSubscriptionsCollectionPage subscriptions = await graphClient.Users[{UserId}]
                                                                               .Drive
                                                                               .Root
                                                                               .Subscriptions
                                                                               .Request()
                                                                               .GetAsync();

Thank you for reaching out. To my knowledge, there isn't currently a way to do this with MS Graph, since listing the subscriptions doesn't support the OData query params. As a workaround, I would suggest fetching the list then filtering by the resource param client side once the response is sent by graph:

/users/{UserId}/messages

Would you consider filing a feature request on the M365 developer platform so this can be looked into?
