Outlook Web: Change Conversation View

To change conversation view in Outlook on the web, select Settings (the gear icon) > Mail > Layout, then under Message organization choose Show email grouped by conversation or Show each message separately. If you keep conversations grouped, you can also choose whether the newest or oldest message appears at the top.

Change the conversation setting

The setting is in Outlook’s mail layout options, rather than in the message list’s sort controls. Use these steps in a web browser:

Open Outlook on the web and sign in to the mailbox you want to change.
Select the gear-shaped Settings button near the upper-right corner.
In the settings panel, open Mail, then Layout.
Find Message organization and select the display you prefer: grouped by conversation or each message separately.
If you selected grouped conversations, choose the order for messages within each conversation, if that option is shown.

Outlook usually applies settings changes automatically, though the exact panel and labels can vary as Microsoft updates the interface or between account types. If a save button appears, use it. If you do not see the setting immediately, expand the Mail settings or use the settings search box, if available, to look for “conversation.”

What conversation view changes

Conversation view collects related messages into a thread in the message list. Instead of seeing every reply as its own row, you see one conversation entry that represents the exchange. Selecting it lets you review the messages belonging to that conversation, often by expanding individual messages or moving through the thread in the reading pane.

Outlook uses message and conversation information to associate replies; grouping is not simply a visual rule that combines every email with the same subject. Replies that remain part of the same exchange are more likely to appear together, while a separately composed message with a similar subject may remain separate. Changes to a subject, forwarding, or differences in how another mail system handles message data can also affect whether a message joins the expected thread.

Turning conversation view off changes how the list is presented, not the messages themselves. It does not delete, resend, or move mail. The individual emails remain in the mailbox, but they appear as separate entries, which can make it easier to spot a particular sender, date, or reply without opening a thread.

Choose grouped or separate messages

Grouped view is useful when you regularly follow long exchanges. A project discussion with several replies, for example, can take up one row rather than filling the inbox with a succession of related messages. Opening the conversation can provide the context of earlier replies, which helps when a response refers to a decision made several messages back.

Separate-message view can suit people who want a conventional chronological list or who find threaded mail confusing. It can also help when you are looking for one specific message and want to scan the sender and received time for each reply directly in the list. The trade-off is that a busy exchange occupies more rows, and the relationship between replies may be less obvious.

Choose grouped conversations if you want related replies collected together and prefer a shorter-looking message list.
Choose separate messages if you want each email to have its own row or need to compare individual messages by date and sender.
Try both views if you are unsure. Switching the display does not remove messages, so you can return to the other option later.

Neither choice changes whether a message is delivered or whether you can reply. It is a display preference, not a rule for how senders’ emails are handled.

Set the order within a conversation

When messages are grouped, Outlook may offer a choice about which end of the conversation appears first: newest or oldest. Newest on top puts the latest reply in the most prominent position, which is convenient if you mainly need to act on the current response. Older messages are still part of the conversation and can be opened to follow the history.

Oldest on top presents the exchange in the order it unfolded. That can be easier when reading a thread from its beginning, especially when later messages quote only parts of earlier discussions. It may mean scrolling through the earlier messages to reach the latest reply. This ordering affects the presentation inside the conversation; it is distinct from the overall sort order of the inbox.

If you cannot find an order option, first confirm that grouped conversations are selected. The available controls and their wording can differ across Outlook web interfaces, and some layouts may show the order choices only after conversation grouping is enabled.

Conversation view versus inbox sorting

Conversation grouping and message sorting solve different problems. Sorting arranges entries in the list, usually by date, sender, or another available criterion. Conversation view decides whether related messages appear together as a thread or separately. If the inbox seems to be in an unexpected order, check both the sort control in the message list and the conversation setting in Mail layout.

For example, selecting newest on top inside a conversation does not necessarily make the entire inbox sort by sender. Likewise, changing the inbox’s date order does not turn conversation grouping on or off. Keeping these controls separate helps diagnose why a message appears in a particular place.

Search is another separate tool. Searching for a sender or phrase can help locate a message whether the inbox is grouped or not, although the results may be presented as individual messages or as conversations depending on the interface and current settings. Open the result and check the sender and date if you need to confirm that it is the exact reply you wanted.

When the setting does not seem to work

If the message list looks unchanged after switching views, allow the page a moment to update and refresh Outlook. Make sure you changed the setting in the mailbox you are currently viewing; a browser can have more than one account signed in, and settings for one account do not necessarily change another account’s mailbox. Also check whether you selected grouped view or separate messages in the final setting rather than only changing message order.

The option is missing: Open the full Mail settings and look under Layout for Message organization. A staged interface update or account type may use different labels or panel organization.
Only some replies are grouped: Outlook may not recognize every similar-subject email as part of one conversation. Check whether the message is a reply in the original exchange rather than a new email with a matching subject.
A message seems hidden: Expand the conversation and inspect its messages. Also check the folder, search filters, and focused or other inbox views if you use them.
The change does not appear on another device: Confirm that the other app is using the same account and check its own conversation display settings. Web, desktop, and mobile interfaces can expose separate controls.

When checking a thread, use the message details and timestamps rather than relying only on the row count. A grouped conversation can make several emails look like one item in the list even though each email remains individually available.

How Outlook web compares with desktop and mobile

Outlook on the web and the Outlook desktop applications do not always place conversation controls in the same menu. In the web version, the standard route is Settings > Mail > Layout > Message organization. In classic Outlook for Windows, conversation options are generally managed from the View tab, including the Show as Conversations control. The wording and exact location can differ in the newer Outlook for Windows, so do not assume a desktop instruction applies to the browser.

Outlook mobile also has its own settings and interface. If you change the web setting but still see a different arrangement in the mobile app, look for a conversation or message organization option in that app rather than repeatedly changing the browser setting. The goal is the same, but a setting’s availability and synchronization can depend on the app and account configuration.

This distinction matters for shared or work mailboxes too. You may be viewing a mailbox through a different Outlook experience or with organization-managed settings. If the control is absent or locked, your organization’s configuration or the particular mailbox interface may limit what you can change; consult your Microsoft 365 administrator or help desk.

Frequently Asked Questions

Can I turn off conversation view in Outlook on the web?

Yes. Go to Settings > Mail > Layout, find Message organization, and select Show each message separately. The emails remain in your mailbox; they are no longer grouped in the list.

Does changing conversation view delete or move emails?

No. It changes how Outlook displays messages. It does not delete or move them. If a message is hard to spot, expand its conversation or search for it by sender, subject, or text.

Can I put the newest reply at the top?

Yes, when grouped conversations are enabled and the order choice is available. In the same Message organization area, choose the newest-first option. The wording may vary slightly between versions of Outlook on the web.

Why are emails with the same subject not in one conversation?

A matching subject alone does not guarantee that Outlook treats two messages as the same conversation. A new message, a changed subject, or differences in the message information supplied by a mail system can result in separate entries.

Will the setting change Outlook on my phone or computer?

Not necessarily. Outlook’s web, desktop, and mobile experiences can have separate display controls. Check conversation settings in each app where you want the same layout.
