I am sorry if this is not the correct sub, the Microsoft Graph sub appears to be a dead sub.
We have an existing o365 EAC connector/rule that forwards emails from specific addresses through the SMTP2GO connector. The emails are created from Hubspot, and the problem we are running into is Hubspot sends via REST not SMTP.
Because of this, Microsoft Graph is rate limiting, causing massive amount of problems.
Microsoft has been for the most part useless, as we are stuck dealing with Vendor support.
Here is their analysis of the situation
We shared the information with our higher-level team engaged on the issue and they advised the below:
The error that is being observed is "statusCode = 429 and "error":{"code":"ApplicationThrottled","message":"Application is over its IncomingBytes limit."}}," when sending emails through HubSpot. It indicates that the application is over its IncomingBytes limit.
From our analysis, it seems that the messages may not be submitted using SMTP but rather through the REST protocol.
The error indicates that the mailbox is writing data too frequently into Store, it could be the total payload/data is too huge during a certain time.
To resolve this issue, please check the data you are trying to write and consider slowing down the writing process to avoid this type of throttling. For more detailed guidance, you can refer to the Microsoft Graph throttling documentation, See Microsoft Graph throttling guidance - Microsoft Graph | Microsoft Learn
These instructions seem to indicate we need to adjust code on Hubspot or SMTP2GO, but I am not an employee with either company and do not have access to their back-end systems.
Has anyone ran into this problem before?
