Understand the Sorting Limitation in Outlook on the Web

Currently, Outlook on the web does not sync or inherit the custom sort order from OneDrive.

Microsoft Outlook on the web uses a separate or limited sorting method for its attachment picker. Even if you change the default folder order to alphabetical in OneDrive for the web, this change will not affect the order shown when you try to insert a OneDrive file in Outlook for the web. Currently, there is no built-in setting to force alphabetical sorting in the attachment menu.

1
Verify OneDrive settings

Open OneDrive for the web and confirm your folders are set to sort alphabetically. Note that this is for your own organization and won't affect Outlook.

No Current Workaround: Microsoft Community Moderators have confirmed this behavior, and there is currently no reliable workaround to force the alphabetized view in the attachment picker.

Frequently Asked Questions

Why aren't my OneDrive files alphabetized when I attach them in an email?

Outlook on the web uses an independent sorting mechanism for its attachment picker. It does not currently inherit the alphabetical sorting preferences you set in OneDrive for the web.

Can I manually rearrange folders in the Outlook web attachment picker?

No, Outlook on the web does not currently provide an option to manually rearrange or sort folders directly within the attachment picker window.

Will Microsoft fix the OneDrive folder sorting issue in Outlook?

Microsoft relies on user feedback to prioritize fixes. While community moderators have acknowledged the issue, the best way to encourage a fix is to submit a report via Help > Feedback > I do not like something in Outlook on the web.

Does this issue affect the Outlook desktop application?

This specific limitation is primarily observed in Outlook on the web. The Outlook desktop application integrates differently with Windows File Explorer, which natively respects your standard alphabetical sorting preferences.
