Create subscription for Inbox folder's subfolders and How do we perform Subscription for multiple folders in one request similar to EWS

With reference to the GRAPH API mentioned at https://learn.microsoft.com/en-us/graph/api/subscription-post-subscriptions?view=graph-rest-1.0&tabs=objc:

  1. How can I subscribe for new message notifications to Inbox's subfolder.(Let's say that I have a testFolder as subfolder inside Inbox.

  2. With EWS, I can specify all folder IDs for which I want to subscribe for new message Notifications in single request. Is there a way to achieve the same with Graph API i.e. subscribing for new messages in multiple folders in single request by passing all folders ids/names?

Solution

  • You have to subscribe to each folder separately, the notifications do not bubble up to the parent folder.

    To subscribe to the subfolder, the resource value should be something like: users/{a}/mailFolders/{b}/childFolders/{c}/messages

    Where a is the id or email of the user, b the is of the main folder and c the id of the subfolder
