How to Fix It
It appears you aren't in the same organization as the group (or a sub-group) you're sending to or your
email address isn't on the group's allowed senders list. Ask the owner of the group to grant you
permission to send to it, and then try again. If the group belongs to a different organization than
yours, contact the organization's customer service department for assistance. If the group is in your
organization and you don't know who the group owner is, you can find it by doing the following in
either Outlook on the web or Outlook:
• Open your Sent folder and select the original message.
• If you're using Outlook on the web, select the group name located on the To or CC line. If you're
using Outlook, double-click the group name located on the To or CC line.
• In Outlook on the web, from the pop-up dialog box, choose Owner. In Outlook, choose Contact. The
owner's name is listed under Owner.
The owner of the group may have intentionally chosen to restrict who can send messages to it, and they
may not want to adjust the existing restriction. In this case, you'll have to contact the group
members by some other means, such as sending an email message to their individual email addresses or
contacting them by phone.

More Info for Email Admins
Status code: 550 5.7.133

This error occurs when the distribution group, security group, or Microsoft 365 group is configured to
accept messages only from authenticated senders (senders in the same organization or those added to
the group's allowed senders list).

To fix the issue, the recipient's email admin or the group owner must add the sender's email address
to the group's allowed senders list or change the group's delivery management setting to accept
messages from senders inside and outside of the organization.

Usually this issue can only be fixed by the recipient's email admin or the group owner.

For more information and steps to fix this error, see [2]Fix email delivery issues for error code
5.7.133 in Office 365.
