Hello,
I'm working on a user report for our product that they are unable to create a subscription for their calendar. In our backend we're making a POST to https://graph.microsoft.com/v1.0/subscriptions , and it is returning a 503. We have a significant number of users that are able to perform this operation, yet every time this user tries we get a 503. According to the the docs, this should only happen because of a capacity issue and we should try again, but every attempt for this user gives us a 503.
I'm not sure what to do from here. We can ask them to keep trying, but it seems like something else is going on. Are there user-specific reasons why this endpoint might return a 503, and how can we prevent it?
Thanks,
Chris

Some of our users keep getting a 503 when we do a POST to create a subscription to the App-folder (/me/drive/special/approot) and retrying the request has zero effect. I can add that other actions are working as intentend, we are able to browse the app-folder, create and delete files, but our functionality is dependent on the subscriptions webhook. This does not affect all users, but I have yet to find out why some users are seeing this,
The error that is returned to us is: [Status Code: ServiceUnavailable; Reason: User content migrated. Cannot access disabled item.]
