Junk Filters

Exchange Online Junk Filters

The junk filtering component of Exchange Online is designed to be flexible, adapting to individual user input. It's a good idea to regularly review messages in the Junk Email folder to check for legitimate messages that were incorrectly classified as junk.

By right clicking on a message in the Junk folder and selecting the “Not Junk” option, a user can gradually train the filter to be more accurate and effective. There are also options to specify safe senders and blocked senders. These features of Exchange Online represent a vast improvement over our previous spam filtering capabilities (see below), which were not user configurable on an individual basis.
