Guidance on spam processing and junk mail

If you find a message that is not junk you can mark the item as not junk and the message will be moved to your Inbox and the sender will be added to your Safe senders and recipients list.

Outlook on the Web users can find out more about junk email and phishing and the actions they can take to manage their junk email.

Outlook for PC and Outlook for Mac users can manage their junk mail using the Junk Email Filter in Outlook.

Junk email reporting lets you report junk email to Microsoft for analysis to help improve the effectiveness of the junk email filtering technologies.

This can only be reported using Outlook on the Web. When you mark a message as junk or not junk, you will see a dialog box that asks you if you want to send a copy of the message to Microsoft to improve the accuracy of the junk email filter.

If you still find that some persistent spam or unwanted personal messages continue to arrive in your Junk E-mail folder you can either create a rule on the Junk E-mail folder to delete certain emails immediately or use Blocked Senders.

Outlook clients have an additional junk mail filter that can be used in addition to the central Exchange Online Protection service (EOP).

By default, the Junk Email Filter protection level on the Outlook client is set to No Automatic Filtering. However, you can make the filter more aggressive so that it catches more junk messages.

The higher you set the protection level, the greater the risk of some legitimate messages being identified as junk and moved to the Junk E-mail folder.

Not all Email sent from an @unit.ox.ac.uk address is sent from Nexus365. There are a few scenarios where internal Oxford Email will originate from outside of Nexus.

•    Units that run their own mail service 
•    Third party mail distribution tools and systems 
•    Individual users with clients configured to send via an unauthenticated SMTP service

Email sent from any of the above scenarios will be scanned by Exchange Online Protection (EOP) along with all the other incoming mail into Nexus.

The junk E-mail folder will automatically delete content from the Junk E-mail folder after 90 days.
