What Is the Navigation Pane Grouping Option?

In Outlook, the navigation pane displays icons or text labels for the main modules: Mail, Calendar, People, Tasks, Notes, and any custom folders you’ve added. In practice, when you select a module (e. Now, , Mail), the pane can also show a hierarchical list of folders, sub‑folders, and favorite items. g.Now, for example, in the Mail view you might see your Inbox grouped by “Date” (Today, Yesterday, Last Week), by “Conversation”, or by “Categories”. Which means the grouping option determines how Outlook organizes those items within the selected module. Changing this setting alters the visual grouping without moving or deleting any actual data.

Prerequisites

• Microsoft Outlook (desktop version) 2016, 2019, 2021, or Microsoft 365 subscription.
• A mailbox with at least one folder (Inbox, Sent Items, etc.) to test the change.
• Basic familiarity with the Outlook ribbon (Home, View, Folder tabs).

Note: The steps below apply to the classic Outlook desktop client. The web version (Outlook on the web) and mobile apps have limited grouping controls, but the concepts are similar.

Step‑by‑Step Instructions

1. Accessing the View Settings

1. Open Outlook and ensure you are in the module whose navigation pane you want to adjust (e.g., click the Mail icon).
2. Locate the View tab on the ribbon at the top of the window.
3. In the Current View group, click View Settings (the small gear‑shaped icon).
   • This opens the Advanced View Settings dialog box.

2. Modifying the Grouping Criteria

1. In the Advanced View Settings window, click the Group By… button. - A new dialog titled Group By appears, showing the current grouping fields (if any).
2. To remove all grouping, select (none) from the Group items by dropdown list, then click OK.
3. To apply a different grouping, choose a field from the list (e.g., Received, Categories, Flag Status, From, Subject).
   • You can add up to four grouping levels by clicking the Add button after selecting a field. - Use the Sort buttons (Ascending/Descending) to control the order within each group.
4. If you want Outlook to automatically expand or collapse groups, check the corresponding checkboxes at the bottom of the dialog (Automatically group according to arrangement and Show groups in collapsed form).
5. Click OK to close the Group By dialog, then click OK again in the Advanced View Settings window to apply your changes.

3. Saving and Applying Your Changes

• Outlook applies the new grouping instantly; you’ll see the navigation pane (or the item list within the selected module) update without needing to restart.
• To make this grouping the default for all folders of the same type (e.g., all Mail folders), check the Apply this view to other mail folders option in the Advanced View Settings window before clicking OK.
• If you only want the change for the current folder, leave that option unchecked.

Tip: You can create multiple custom views (e.g., “Flat List”, “By Category”, “By Date”) and switch between them via the Change View dropdown in the Current View group.

Customizing Group Appearance

• Expand/Collapse State: By checking Show groups in collapsed form, Outlook starts each session with the most relevant groups already collapsed, reducing visual clutter.
• Header Text: You can rename a group’s header by editing the Group header field in the Group By dialog; this provides a more descriptive label than the default field name.
• Sorting Within Groups: After grouping, use the Sort buttons to order items inside each group (e.g., sort by From ascending or Received descending) without leaving the Group By dialog.

Switching Between Saved Views

Outlook lets you store multiple grouping configurations as separate Views. To toggle between them:

1. Click the Change View dropdown in the Current View group of the ribbon.
2. Choose the desired saved view from the list, or select Views… to open the Views dialog and pick a different configuration.

Each saved view retains its own grouping criteria, expansion state, and column arrangement, enabling you to switch contexts with a single click.

Conclusion

Outlook’s grouping capabilities transform a chaotic inbox or calendar into a structured, easily navigable workspace. Even so, whether you need a flat, unfiltered list for quick scanning or a hierarchical layout that clusters messages by project, category, or date, Outlook provides the flexibility to tailor the view to your exact needs. By accessing the View Settings dialog, selecting or creating the grouping fields that matter most to your workflow, and optionally saving those configurations as distinct views, you can dramatically improve efficiency and focus. With the steps and options outlined above, you now have a complete roadmap for mastering grouping controls—empowering you to organize your mail, tasks, and calendar items exactly the way you work best.
