Email a Group

You can email an EMS group whether your organization uses Microsoft Outlook or SMTP. Recent updates to EMS email functionality now require OAuth authentication for SMTP, in line with Microsoft’s retirement of Basic Authentication for Exchange Online (effective April 30, 2026). This change enhances security and ensures ongoing compatibility for organizations using external SMTP servers​.

Requirements

Microsoft Outlook: You may continue to use Outlook to send emails to EMS groups as before.

SMTP: To email an EMS group using SMTP, your user account must have an email address. Additionally, your organization must configure OAuth for SMTP or Exchange environments. This involves setting up Client ID, Client Secret, and Token URL in EMS​​.

Steps to email a group

  1. Search for the group

    1. Locate the group you wish to email in the Groups window.

  2. Choose your action

    1. Option 1: Select the group and click Email.

      1. Depending on your system configuration, a pre-addressed Outlook or SMTP email form opens.

      2. The To field is populated with the group’s email address, which you can edit if needed.

    2. Option 2: Select the group and click Open.

      1. In the group-specific window, ensure the group is selected in the left pane, then click Email.

      2. Again, a pre-addressed Outlook or SMTP email form opens, with the group’s email address in the To field.

  3. Complete and Send the email

Important notes

For SMTP users, ensure OAuth is configured in your EMS environment. This is now required for secure email delivery and continued support​​.

Only booking-level changes in reservations will trigger Outlook updates; reservation-level changes (such as source or URL) are logged but do not send updates​.
