Application is over its MailboxConcurrency limit issue RRS feed

  • Question

  • Hi All,

    We  have integrated our application with MS exchange online using graph api and while doing automation tests my tester created 500 draft emails messages every 15 min and ran test for 2 hr. We see response for this api call as  below error but Emails got created in the back end successfully . Any one has faced this issue ?  I dint find any  helpful text in limitations regarding Mail Box concurrency limit in official docs.  I found this link https://itconnect.uw.edu/connect/email/exchange-online/tips-tricks/limits-of-uw-exchange-online/ which mentions limit as 32. 

    ” {"status":429,"body":{"code":"ApplicationThrottled","message":"Application is over its MailboxConcurrency limit.","innerError":{"request-id":"473b75cc-e854-4ba6-b94f-e51d62e5fdaa","date":"2020-06-09T12:01:01"}}}
