The group unisapress only accepts messages from people in its organization or on its allowed senders list, and your email address isn't on the list. mauve-patches Office 365 unisapress Sender Action Required Sender not allowed 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. Was this helpful?

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 Fix email delivery issues for error code 5.7.133 in Office 365.
