Office 365 users are restricted to a 10MB attachment Limit RRS feed

  • Question

  • Hi Team,

    We currently have a hybrid setup of Exchange 2013 and Office 365. 

    Our 365 users are unable to receive attachments larger than 10MB. I have looked everywhere and assume the issue lies within the transportconfig setting our ExternalDsnMaxMessageAttachSize and InternalDsnMaxMessageAttachSize at 10MB

    In our On prem exchange I can change these values, however in 365 it appears as though they have deprecated the commands to change these values.

    Does anyone know how I can remedy this situation?

    Regards
