Email Router and Office 365 RRS feed

  • Question

  • Hi Folks

    We have recently Migrated from an on-premise Exchange solution to Office 365 and an Exchange Online Solutions

    All the tests done when configuring the email router work ok

    outbound emails work ok

    With inbound emails (especially for queues) we are sometimes getting an 'Internal Server Error' response.

    We have managed to dig down and have found that the underlying error message in this case is the following 

    Message: An internal server error occurred. The operation failed.

    Type: Microsoft.Exchange.WebServices.Data.ServiceResponseException
    Source: Microsoft.Exchange.WebServices
    ErrorCode: ErrorInternalServerError
    InnerErrorMessageText: Too many concurrent connections opened.
    InnerErrorResponseCode: ErrorTooManyObjectsOpened
    InnerErrorDescriptiveLinkKey: 0

    ErrorMessage: An internal server error occurred. The operation failed.

    What settings should (or can) I use to throttle the email router down to the level that Office 365 will accept
