As part of Microsoft 365, the mail server will check incoming mail for potential spam mail. If an e-mail has been caught by the filter, it will be sent to the Junk E-mail folder, where it will temporarily remain until the system deletes it. At certain times, there is a small chance that non-spam mail will be caught by the filter. As a result, mail which should be delivered to your Inbox is instead sent to your Spam or Junk mail folder.
In order to mark an e-mail address as legitimate, one can add the mail sender to their safe senders list. This will flag the e-mail address as safe, and automatically allow it to pass through to your Inbox when the sender mails you again in the future. To add an e-mail address, to your safe senders list, please do the following:
Adding Safe Senders via Outlook
- First open your Outlook.
- Navigate to your Junk E-mail folder.
- Right click on the e-mail in question which you want to mark as safe.
- In Outlook Web Access select Security options.
- In Outlook select Junk
- Now select Mark as not junk. This will then prompt whether to trust the address and add it to your Safe Sender’s List.
- Once you have select OK, you will then receive an alert that the sender or domain has been added to your Safe Sender’s list.
Please also note that e-mail from an ou.edu domain address will always be considered safe by the Exchange mail system. If an OU e-mail has been flagged as spam, you may wish to see if some other security software on your computer has flagged it as such.
