    Hi @Bernie Rashford ,

    Remote Server returned '550 5.7.705 Service unavailable. Access denied, tenant has exceeded threshold.

    From the error message, seems like your organization is encountering the issue as described in the document below:
    "Tenant has exceeded threshold" NDR when mail is sent from your organization

    Please try to contact the Exchange administrator in your orgnization as this needs to be dealt with by the administrator. You can share the article above with the administrator if necessary.

    Hi,

    Remote Server returned '550 5.7.705 Service unavailable. Access denied, tenant has exceeded threshold

    Yes, i am also been receiving this error. I have disenabled one of the connectors which somehow may be hacked by someone or so. However I am still unable to send out any emails and couldn't reach any Microsoft support personnel.

    I seriously need some help here. and how to resume my outgoing email

    Thanks, Andy from Singapore
