Shared Office 365 mailboxes are quite useful in many scenarios. We use one of them for task automation, when external Microsoft Flow is triggered based on incoming email. Recently some valid email were blocked by junk email filter, here is the way how junk filter could be disabled.
- Go to https://outlook.office365.com/ecp/your_email@your_domain.com (replace your_email@your_domain.com with your own shared mailbox email address)
- Click "block or allow" on the left pane
- Click "Don't move email to my Junk Email folder" radio button
