How do I filter search results to only include unread messages in Office 365 outlook.com? I've tried read:no, but that looks for messages containing read and no.

Office 365 Outlook Search

5 Answers 5


I was also struggling to get all the unread emails (including from the subfolders) in Outlook Office 365. The closest I could find was the following search query:


Search Email

In case of Desktop client, this can be achieved with the Search Folders.

Search Folders -> Right Click -> New Search Folders -> Unread Mail

But, unfortunately this feature is not available yet for the Office 365. Here is the uservoice link for this search folders:

UserVoice - Outlook Office 365 Search Folders

  • isread:no search is available in web outlook, "unread search folder" is not Jul 27, 2020 at 18:27
  • Not a good sign, that link is broken and MS is moving away from UserVoice. Now just 'submit your feedback' to a blackhole help icon. windowscentral.com/… Sep 15, 2021 at 4:10

At the top of the interface for a folder (e.g., Inbox), next to the folder name, there's a pull menu called Filter. Pull that down and select Unread.


Please take a look on the screenshot below where "filter" is circled on the right. We have to simply filter with "Unread".

  • This query is for unread accross all folders, not folder specific.

While you can filter for Unread messages in any folder, that search does not seem to include subfolders at all. Since the SearchFolders feature isn't yet available in the Outlook Web App, there is no way to store the filter/search you have to now manually perform everytime.


Continuing this issue, I would very much appreciate help when it comes to the following; and I believe others could also make use of a solution! In Outlook 365, I would like to add a macro (button in the ribbon) that simply filters out all unread email messages in the current folder (the one that is currently open), using, for example, isread:no. What would such a VBA script look like? Thank you! Best regards, /Pelle
