How to Customize Outlook Mobile Quick Filters: Unread and Flagged and Attachments

You want to find specific emails faster in the Outlook mobile app. The inbox can become cluttered, making important messages hard to spot. Outlook provides Quick Filters to instantly show only unread, flagged, or emails with attachments. This article explains how to add, remove, and reorder these filters on your phone.

Key Takeaways: Managing Outlook Mobile Quick Filters

  • Filter icon (funnel): Tap this icon above your inbox list to open the Quick Filters menu and apply a filter.
  • Edit button (pencil): Tap this button in the filter menu to enter edit mode and customize which filters are available.
  • Drag handle (three lines): Press and hold this icon next to a filter name to drag it into your preferred order.

Understanding Outlook Mobile Quick Filters

Quick Filters are buttons that apply a predefined search to your current mailbox view. They appear as a row of tabs above your email list after you tap the filter icon. The default set usually includes Unread, Flagged, and Attachments, but this can vary.

These filters work locally on your device by sorting the emails already downloaded to your inbox. They do not perform a server-side search. You must be in the main inbox or a specific folder for the filter icon to appear. The customization you perform is saved per account on your device.

Available Filter Types

Outlook for iOS and Android offers several filter types beyond the common three. You can add filters for emails that are only To you, or that have specific categories. A useful filter is Unread, which shows all emails you have not opened yet. Another is Flagged, which displays items you have marked for follow-up.

The Attachments filter shows only emails with file attachments. The To Me filter excludes CC and BCC messages, showing only emails where you are the primary recipient. You can enable or disable any of these based on your daily workflow needs.

Steps to Add or Remove Quick Filters

Follow these steps to change which filters appear in your quick selection menu. The process is nearly identical on both iOS and Android devices.

  1. Open the Outlook app and go to your inbox
    Launch the Outlook mobile app. Ensure you are viewing the main inbox for the account you want to customize.
  2. Tap the filter icon
    Look for the funnel-shaped icon at the top right of your email list, next to the search bar. Tap it to open the current Quick Filters bar.
  3. Tap the Edit button
    In the filters menu that slides up, you will see an Edit button, often represented by a pencil icon. Tap this button to enter customization mode.
  4. Add or remove filters
    You will see a list of all available filters with toggle switches or plus/minus icons. To add a filter, switch its toggle to the on position or tap the plus icon. To remove one, switch it off or tap the minus icon.
  5. Confirm your changes
    Tap Done or a checkmark at the top of the screen to save your new filter selection. The Quick Filters bar will now show your updated choices.

How to Reorder Your Quick Filters

After choosing your filters, you can arrange them. Place the ones you use most often on the left for easier access.

  1. Enter the filter edit mode
    Repeat the first three steps above: open your inbox, tap the filter icon, then tap the Edit button.
  2. Press and hold the drag handle
    Next to each active filter name, you will see an icon with three horizontal lines. Press and hold this icon for the filter you want to move.
  3. Drag the filter to a new position
    While holding, drag the filter up or down the list to your preferred order. Release your finger to drop it into place.
  4. Save the new order
    Tap Done to save. The filters will now appear in your chosen sequence from left to right on the Quick Filters bar.

Common Mistakes and Limitations

Filter Icon Is Missing from the Inbox

The filter icon only appears when you are viewing a standard mail folder like Inbox, Sent Items, or a custom folder. It does not appear in search results views or within the Focused Inbox tab if it is not the primary view. Navigate back to your main inbox list to restore the icon.

Filters Not Showing All Expected Emails

Quick Filters only work on emails already synced to your device. If you have a very large mailbox, some older messages may not be in the local cache. For a complete search, use the main search bar at the top of the screen instead of a Quick Filter.

Customizations Reset After App Update

Rarely, app updates can reset personalization settings. If your filter order reverts, simply re-enter the edit mode and set them up again. Your filters are stored locally, not on your Microsoft account, so reinstalling the app will also erase them.

Cannot Create a Custom “Unread and Flagged” Combined Filter

The standard Quick Filters are single-condition only. You cannot create a combined filter for emails that are both Unread and Flagged through this menu. To do this, you must use the advanced search feature by tapping the main search bar and selecting filters from there.

Quick Filters vs. Search Filters: Key Differences

Item Quick Filters Search Filters
Access Method Funnel icon above the inbox Main search bar at the top
Speed One-tap application Requires multiple taps to set criteria
Customization Can reorder and choose from preset list Can combine multiple conditions like date and sender
Scope Only works on currently loaded emails Searches entire mailbox on the server
Persistence Filter remains active until you tap it again Search results view exits when you go back

You can now tailor your Outlook mobile inbox to highlight unread messages, flagged items, and attachments with a single tap. Set your most used filter as the first option for the fastest access. For more complex sorting, remember to use the advanced search filters available from the main search bar. Try using the To Me filter to reduce noise from group emails in a busy inbox.
