How to Set Email as Safe in Office 365

Are emails from Penelope always being flagged as spam? Check here!

Updated over a week ago

Microsoft has deprecated functionality that Penelope used to rely on, so most email/external communications issues can be resolved by switching to Centralized Email Sending (aka SendGrid!).

These instructions are for agencies sending email from Penelope using Office 365 email servers. They are to be used when needing to unblock a sending email account when using external messaging features in Penelope.

Description of Issue #1

Depending on the structure of some of the messages sent from Penelope, sometimes the receiving email server (eg Hotmail, Gmail, Corporate email etc) will mark the message as spam.

If this occurs in high enough volume, Office 365 (for the sending account) has a security process that marks the account itself as being used to send spam. The sending account is then blocked by Office365 from being used to send outgoing mail.

Step-by-Step Guide

Pre-requisite: Admin level account credentials for Office365.

You will see a warning at the end of this process indicating that it can take up to an hour to clear the issue for that account.

Important Information

This is something that needs to be done periodically as the account can be put back into the state/error above recurrently.

Steps Involved to Fix the Issue

  1. Log in to Office 365 admin with an account with Admin setting/Access.

  2. Click on the square to display the list of apps.

  3. Click on All apps.
