In the fast-moving world of modern communication, your inbox can quickly turn into an unmanageable pile of unread messages, urgent tasks, and forgotten follow-ups. Fortunately, Microsoft Office for Mac 2016 includes Outlook 2016, a feature-rich email client equipped with powerful tools to organize your inbox—and one of its most underrated features is Categories.
Categories in Outlook allow you to color-code emails, calendar events, contacts, and tasks. With just a glance, you can spot what’s important, what needs follow-up, and what can wait. This blog will guide you through everything you need to know about Outlook 2016 Categories and how to use them to master email sorting and boost productivity.
Why Use Categories in Outlook 2016?
Here’s what Categories help you achieve:
- Visual organization through color-coding
- Quick filtering of messages or appointments
- Centralized tracking across email, calendar, and tasks
- Custom workflows for sales, HR, IT support, and more
- Efficient searching and sorting
Categories are more powerful than folders because they allow multiple tags per item. Unlike moving emails to a single folder, categorizing keeps them accessible while still clearly organized.
Getting Started: Accessing Categories in Outlook 2016
To begin using Categories:
- Open Outlook from your Microsoft Office for Mac 2016.
- Right-click any email message.
- Choose Categorize from the context menu.
- Select an existing category or click All Categories to edit or create your own.
How to Create and Customize Categories
Customizing Categories helps tailor them to your work style.
Steps to Create a Custom Category:
- Click Home > Categorize > All Categories.
- Click New.
- Enter a category name (e.g., “Follow-Up,” “Sales,” “HR Tasks”).
- Choose a color that makes the category visually distinct.
- Click OK.
You can also:
- Rename default categories
- Assign shortcut keys (e.g., Ctrl+F2)
- Delete unused ones

- Using shortcut keys, if assigned
- Drag-and-drop in the Message List, if you’ve customized columns to show Category
Multiple categories can be assigned to a single message for deeper context.
Sorting and Filtering with Categories
Categories really shine when combined with Outlook’s filtering tools.
Filter Emails by Category:
- Go to your inbox or folder.
- Click the Filter Email dropdown on the Home tab.

Sort Emails by Category:
- Click the Category column header in your inbox (enable it via View > View Settings > Columns).
This helps you group similar tasks or topics regardless of which folder they’re in.
Using Categories Beyond Email
Categories apply to more than just emails. You can use the same labels across:
Calendar Events
- Label meetings by type: “Internal,” “Client-Facing,” “Training”
- Filter your calendar view by category to focus your week
Tasks
- Assign categories to prioritize tasks: “Urgent,” “Today,” “Deferred”
- Use color as a visual prioritization method in your To-Do Bar
Contacts
- Group contacts by role, location, or business vertical
- Make future communication campaigns easier
Notes (if used)
- Color-code meeting notes or project ideas for easy retrieval
Power Productivity Tips with Categories
1. Use Categories for GTD (Getting Things Done)
Create categories like:
- Next Action
- Waiting On
- Someday
- Delegate
This transforms Outlook into a GTD task manager.
2. Create Category-Based Search Folders
- Go to Folder > New Search Folder
- Choose “Categorized Mail”
- Select the category you want
- This dynamic folder now shows only emails with that label
Perfect for task-specific workflows or ongoing projects.
3. Automate Categorization with Rules
Outlook’s Rules can automatically assign categories when:
- A message comes from a specific person
- A subject line contains certain keywords
- A message is sent to a specific distribution list
Go to Tools > Rules > New Rule, then set the conditions and actions.
4. Bulk Categorize Emails
- Select multiple messages using Command + Click
- Right-click and choose Categorize
- Apply your label to all at once
This is useful for old messages or email backlog organization.
5. Assign Categories in Calendar View
Switch to Category view in Calendar to visualize time spent on different meeting types or clients.
Great for productivity tracking or billing purposes.
Common Mistakes to Avoid
- Using too many categories — keep it simple (5–8 categories is ideal).
- Not syncing with mobile apps — some categories may not show up in iOS/macOS Mail apps.
- Overlapping meanings — be consistent in usage across the team.
- Forgetting to review categories — do a monthly clean-up to retire or revise as needed.
How Categories Differ from Folders and Flags
| Feature | Categories | Folders | Flags |
| Multiple Tags | ✅ Yes | ❌ No | ❌ No |
| Visual Aid | ✅ Color-Coded | ❌ Text Only | ✅ Color + Symbol |
| Scope | Cross-item (Mail, Tasks, Calendar) | Mail Only | Mail + Tasks |
| Easy to Change | ✅ Yes | ⚠️ Must drag/move | ✅ One-click |
Use Folders for long-term storage, Flags for follow-up reminders, and Categories for flexible, visual organization.
Transitioning Your System
If you’re moving from an older system or are new to Outlook:
- Start with basic categories like “To Do,” “Reference,” and “Waiting On.”
- Apply them consistently for a week or two.
- Adjust and rename based on what’s working.
- Document your system for team use.
This ensures sustainability and helps teams collaborate with a shared labeling system.
