What is the point of Categories in Outlook

Categories seem like a great thing in Outlook - you can categorise your contacts by adding tags and you can filter your contacts by the categories that you've entered:

But then that's about all you can do with them.

When you create a new email, and you press the "To" button, the dialogue that appears to select your contacts doesn't include categories, so you can't filter contacts by category:

When you export your contacts, your categories aren't included in the export file. 

So, what's the point of categories in Outlook?

    You’ve identified a real limitation: categories help organise contacts in People, but they don’t automatically work as mailing lists or filters in the “To” picker.

    If you regularly email the same group, a contact list in New Outlook/web, or a contact group in Classic Outlook, is more useful. You can address an email to that list by name. The catch is that its membership won’t automatically follow changes to your categories.

    In Classic Outlook for Windows, there’s also a handy route: filter or group contacts by category in People, select the contacts, then choose Home > Communicate > E-mail. That starts the message from the selected contacts rather than using the “To” dialog.

    The export limitation depends on the Outlook version and format—Classic Outlook’s CSV export can include Categories, while other export routes may omit them.

    So categories aren’t pointless, but your expectation is reasonable: being able to filter by them in People and then losing that option when choosing recipients is an awkward gap.

  • Your observation is completely valid. Many people expect Categories to function as an advanced way of organizing contacts, but that isn't really their primary purpose.

    Outlook Categories were designed to act as tags that can be applied across multiple types of items, including emails, calendar appointments, tasks, contacts, and notes. This allows related information to be organized without moving items into different folders. 

    When it comes to contacts specifically, Categories are mainly intended for classification, filtering, and creating custom views. For example, you can tag contacts as "Customers," "Vendors," or "Project Team Members" and then filter or group your contact list accordingly.

    I agree that there are some limitations. In many Outlook versions, Categories are not available as a filter in the recipient selection dialog, and they are not always preserved in certain export formats. This can make them feel less useful for contact management.

    In practice, Categories tend to provide the most value when used with emails, calendar items, and tasks rather than as a contact-grouping mechanism. If your goal is to send messages to a specific set of people, Contact Groups or Microsoft 365 Groups are usually a better fit.

    So while Categories may seem underpowered for contacts alone, they become much more useful
