  3. Include your Company Name in the body of your email.

Raising a Support Case via Phone


Mimecast ID


Before raising a support case by phone, you must have a Mimecast ID. You'll be asked to provide this before being connected to a support engineer. You can find this in your account profile, available in the Administration Console or Connect Application. See the Account & Support Details section of the Administration Console User Interface page for full details.


The Mimecast ID can be either:

  • Your Mimecast ID.
  • The Mimecast ID of the customer account for which you are raising a support case (Partners and Managed Service Providers only).
Entering your Mimecast ID is not currently mandatory. You'll still be connected to a support engineer, but if you don't provide this information, your call will be prioritized behind those customers that have. See our recent Support Details Page & Telephone System Improvements Service Release for full details. We also recommend you follow the Service Updates section of Mimecaster Central to be kept informed of this and other changes.



Before raising a support case by phone, have the following additional information ready:

  • Whether your issue is related to a P1 critical mail flow issue. See the Raising a Priority 1 Support Case section below.
  • The case reference number, if the call is regarding an existing case.

Raising a Priority 1 Support Case


In the unlikely event you need to raise a priority 1 support case, ensure you follow the guidance below. We will respond to priority 1 support cases made by one of your designated contacts on 24 hours a day, seven days a week, and 365 days of the year basis.


Priority 1 support cases must be:

  • Logged for an email or service outage that results in a total loss or significant impairment of your Mimecast services. In this scenario, your organization would not be able to send or receive email, or may not have access to the Mimecast applications.
  • Raised by telephone.


All other support requests will be dealt with in accordance with the level of support purchased.
