We are using Graph API with application credentials - admin login for all tenant users.
Because of some specific heavy user we sometimes reach the throttling limit and receive a 429 error.
Retry doesn't help in this case because the user constantly receiving multiple emails a second.
For example, one of those users is "0719342a-b4b0-4996-a564-eff079bf03ba" in tenant "302fce84-5dde-4410-93e0-7683d18b89c9".
As far, the only feasible solution we see in asking the Microsoft Support Team to increase the throttling rate limit.
- Is it possible for the Microsoft Support Team to increase the throttling limit (for app/for tenant/for mailbox)?
- As far as I see, it is considered the DEV-level support, not the IT-level.
- Which support team should we pointed to, the Azure-AD, the Exchange Server, or something else?
