makeEwsRequestAsync not returning callback on MacO

Question

I'm using makeEwsRequestAsync to get email "Body", "Subject", "MimeContent".

But in case of MacOS Outlook2016 when the email size is more than 1MB the callback method is never called after the call is made to makeEwsRequestAsync(). In case of email having size less than 1MB the callback is called with proper result.

I know in case of more than 1MB email size there will be an error with the message Response exceeds 1 MB size limit. Please modify your EWS request

Also, the same code is working on all browser, Windows Outlook application but only on Mac Outlook2016 the callback is never called.
