Problems receiving webhooks

Question

Hi, since this morning we have issues receiving subscriptions updates on 60 of our client's mailboxes.

Some mailboxes aren't sending any updates at all. Some only partial updates or delayed. Subscriptions are made on a daily basis or if it's mailbox' settings are updated based on this documentation https://learn.microsoft.com/en-us/graph/api/resources/subscription?view=graph-rest-1.0

It's difficult to tell without seeing your setup. This can often happen if there's a URL misconfiguration.

This is not really related to Azure AD though, so I would recommend opening a support case or asking this under Functions (assuming that's where you set the triggers).
