How to Archive All Emails in Your Outlook Inbox at Once

To archive everything in your Outlook Inbox, open the Inbox, select all its messages, and choose Archive. Outlook moves the selected messages into the Archive folder; it does not delete them. Before starting, clear any search or filter so you do not accidentally select only part of the Inbox, and confirm that the correct account is open.

What You’ll Need

Access to the Outlook account and Inbox you want to clear.
A working internet connection if you use Outlook on the web or an account that synchronizes with a server.
A moment to check the selection before archiving, especially if the Inbox contains important or recently received mail.

You do not need to create an Archive folder for most Outlook accounts. Outlook normally provides one automatically. If you use a work or school account, your organization may also provide a separate Online Archive mailbox; that is different from the regular Archive folder.

Step-by-Step

Open the right Inbox. Start Outlook and, if you have more than one account, expand the account list and click the Inbox for the account you intend to clear. Check the account name and folder name before continuing. Archiving from a shared mailbox or another account affects that mailbox, not necessarily your personal Inbox.
Remove searches and filters. If a search term is in the search box, clear it and return to the Inbox. Check for filters such as unread, flagged, or a sender name, and switch the message list back to its normal, unfiltered view. Also check whether you are looking at Focused or Other. Those tabs divide the Inbox in some Outlook versions; they are not separate folders. Your goal is to select messages from the whole Inbox, not just one search result or one filtered subset.
Select every message in the Inbox. The exact control varies by Outlook version:
- Classic Outlook for Microsoft 365 on Windows: Click a message in the Inbox list, then press Ctrl+A. This selects the items in the current folder. Avoid clicking inside the reading pane or a search box first, because the shortcut may act on text instead of the message list.
- New Outlook for Windows or Outlook on the web: Use the selection checkbox at the top of the message list, if shown. If Outlook offers a follow-up option such as selecting all messages in the folder, choose it to extend the selection beyond the currently displayed group. If the interface selects only the visible messages, archive that group and repeat with the remaining messages; do not assume one click selected the entire Inbox.
- Outlook for Mac: Click a message in the Inbox list and press Command+A. If the shortcut highlights page text or does not select messages, click directly in the list and try again. You can also use the list’s select-all checkbox if your version displays one.
Check the selection before moving it. Look for selected rows or checked boxes and note any selection count Outlook displays. Confirm that the messages belong to the Inbox and that no search, filter, or category view has narrowed the list. If the Inbox has more messages than Outlook selected, work in batches: archive the selected group, wait for the list to refresh, and select the next group. This is safer than assuming that a page-level checkbox includes messages that have not loaded.
Choose Archive. In classic Outlook for Windows, use Home > Archive on the ribbon. In new Outlook, Outlook on the web, and Outlook for Mac, select the Archive button on the message toolbar. If the button is hidden, look in the toolbar’s more-actions menu for Archive. Do not choose Delete, and do not use Move to unless you specifically want to choose a different destination folder.
Let Outlook finish the move. Large selections can take time to process, particularly when Outlook is synchronizing with a server. Keep Outlook open and online until the selected messages disappear from the Inbox or the progress indicator finishes. If only a batch was selected, repeat the selection and archive steps for the remaining Inbox messages. Avoid clicking Archive repeatedly while the first action is still running, as this can make it harder to tell which items have moved.
Verify the result. Open the Archive folder in the same account and check that the messages are there. Then return to the Inbox and confirm it is empty, or that only messages you intentionally excluded remain. If the Archive folder is not immediately visible, expand the account’s folder list or use Outlook’s folder search. On a synchronized account, allow a short time for the folder count and message list to update.

Archiving the Inbox does not normally change messages in Inbox subfolders. If you have folders beneath Inbox, open and archive those separately only if that is what you intend. Likewise, archiving one account does not clear the Inboxes of your other accounts.

Common Mistakes

Confusing Archive with deletion. Archive moves mail to a folder named Archive; Delete moves it to Deleted Items. Use the Archive command and verify the destination before emptying or removing anything.
Selecting only the current page or visible group. Some Outlook versions load messages in batches. A selection checkbox may select the displayed messages without selecting every message in the folder. Look for an option to select all messages in the folder, check the selection count, or archive in repeated batches.
Leaving a search or filter active. A search for a person, subject, or unread messages can make it seem as though the whole Inbox is selected when only matching results are selected. Clear the search and filters first.
Using the wrong account or folder. Outlook can display several accounts, shared mailboxes, and an Online Archive. Confirm the account and Inbox name before selecting messages.
Expecting the mailbox to become smaller. The normal Archive folder is generally still part of the mailbox. Archiving organizes mail and clears the Inbox, but it does not necessarily reduce the amount of storage your account uses.

Tips

Try a small test first if you are uncertain. Select one unimportant message, choose Archive, and check where it goes. Once you have confirmed the destination, return to the Inbox and select the remaining messages.
Keep messages you still need easy to find. Search Outlook by sender, subject, or a phrase from the message after archiving. You can also use categories or flags before moving mail if you rely on those to track follow-ups.
Archive in manageable batches for a very large Inbox. Smaller groups are easier to monitor and may be more reliable if the connection is slow. After each batch, wait for Outlook to finish, check the remaining Inbox count, and continue.
Understand which Archive you are using. The regular Archive folder is a folder in the mailbox. An Online Archive, when supplied by an organization, is a separate mailbox area often intended for longer-term retention. The ordinary Archive button does not necessarily move mail into that separate archive.
Use the right keyboard shortcut for your computer. In classic Outlook for Windows, Ctrl+A selects the items in the active folder list; on Mac, use Command+A. In the web app, a checkbox is generally clearer because Ctrl+A can select the whole webpage rather than the messages.
Make a habit of reviewing the Inbox before a bulk move. Archiving all messages is convenient, but it also moves unread mail and messages awaiting a response. If you want to keep a few items in the Inbox, select and archive in batches that exclude those items, or move the exceptions to a clearly named folder first.

Troubleshooting

Archive is missing or disabled: Select at least one message and check the message toolbar’s more-actions menu. In classic Outlook, return to the Home tab and look for Archive. If the control is still unavailable, verify that you are viewing a mail folder rather than a search page or a non-mail folder. Some organization-managed accounts may restrict actions; contact your administrator if the option remains unavailable.

Only some messages moved: Return to the Inbox, clear the search and filters, and check whether Outlook selected only the visible group. Archive the remaining messages in further batches. If a message is still present, confirm that it was not excluded from the original selection or delivered to a different Inbox or account.

The messages seem to have disappeared: Open the Archive folder for the same account and search there by sender or subject. Also check Deleted Items if you may have clicked Delete, and use Undo promptly if Outlook offers it. If you moved messages to another folder by mistake, search for a message and move it back to the Inbox. The exact recovery options depend on your account and organization’s retention settings.

The Inbox still shows messages after archiving: Refresh Outlook or wait for synchronization to complete. Check Focused and Other, any conversation grouping, and the account’s folder list. A conversation view can group several messages into one row, and a newly received message can arrive while you are working. Select and archive any remaining Inbox items once the list has updated.

The Archive folder looks empty: Confirm that you opened the Archive folder under the same account from which you moved the messages, not the Online Archive or another account’s folder. Search Outlook for a message you just archived. If it still cannot be found, check Deleted Items and any custom folders, then contact your organization’s support team if the account is managed.

Frequently Asked Questions

Does archiving all Inbox emails delete them?
No. The Archive command moves messages out of the Inbox into the account’s Archive folder. You can open that folder or search Outlook to find them later. Deleting a message is a separate action.

Will archiving all emails free up mailbox storage?
Usually not if you use the standard Archive folder, because it remains in the same mailbox. It can make the Inbox easier to manage, but storage use may remain similar. Check your organization’s mailbox and retention policies before relying on archiving to reduce usage.

Does this include messages in Inbox subfolders?
No. Selecting all in the Inbox applies to that folder, not its subfolders or other folders. Open each subfolder separately if you also want to archive its contents.

Can I archive only read emails or only older messages?
Yes. Apply an appropriate filter or search, select the matching results, and choose Archive. Check the results carefully before moving them, and clear the filter when you want to work with the entire Inbox again.

Can I undo an archive action?
Often, you can use Undo immediately after the move, or open Archive, select the messages, and move them back to Inbox. The Undo option may disappear after other actions or after time passes, so moving the messages back manually is the more dependable fallback.

Is the Archive folder the same as Online Archive?
No. Archive is usually a regular folder within the account. Online Archive is a separate mailbox feature available for some work or school accounts. If you need to move mail into an Online Archive, use the organization’s instructions or explicitly move the messages to that archive rather than assuming the Archive button does it.
