Guide to Organizing Outlook Messages

If you receive a lot of email messages and need a way to organize them, group your email messages into categories in Outlook. Outlook provides a starting list of categories. Rename these categories to fit your needs and add more categories if you want. Then, when you want to find messages in a category, filter your message list to show categorized emails. There are multiple ways to clean up and streamline your Outlook inbox:

  • Set up a folder for each topic.
  • Create categories as you need them and add more folders.
  • For email that falls under multiple categories, give each message a categorization in the message list.
  • Outlook applies categories automatically with certain intelligence to mark newsletters, social updates, shipment notices, and advertisements.
