How to Move All Emails to the Archive Folder in Outlook

To move emails into Outlook’s Archive folder in bulk, open the folder you want to clear, select its messages, and choose Archive. This keeps the messages in your mailbox rather than deleting them. Outlook applies this action to the folder you are working in, so to archive mail from several folders, repeat the process in each one. Before starting, check that you mean the regular Archive folder, not a separate Online Archive mailbox.

What You’ll Need

Access to the Outlook mailbox containing the messages.
A moment to decide which folders are in scope, such as Inbox, Sent Items, or custom folders. The steps below work with Outlook for Microsoft 365 on Windows; web and Mac differences are noted.
An internet connection if your mailbox is hosted online, so Outlook can sync the changes.

Step-by-Step

Decide what “all emails” means for your task. If you want to empty only the Inbox, work only in Inbox. If you want to move messages from the whole mailbox, you will need to process each mail folder that contains messages, including Sent Items or any custom folders you want included. Archiving Inbox messages does not automatically archive messages in other folders. Decide whether to leave folders such as Drafts, Junk Email, and Deleted Items alone; those folders have their own purposes and often should not be treated as ordinary mail to keep.
Find the correct Archive destination. In the folder pane, look for a folder named Archive under the mailbox you are changing. Outlook’s Archive command normally moves messages to that folder in the same mailbox. It is not the same as an Online Archive or In-Place Archive, which some work or school accounts provide as a separate mailbox. If you have both, make sure you understand which destination you intend to use. If the Archive folder is not visible, expand the mailbox and folder list, or use Move to locate the folder before proceeding.
Open the first folder and clear any filters. Select Inbox or another folder in the navigation pane. If the message list looks incomplete, check whether a search is active, a filter is applied, or the list is showing only unread or flagged messages. Clear the search and filters if your goal is to select everything in that folder. In Outlook on the web, also check whether you are viewing a focused or filtered list; the archive action only affects messages included in your selection.
Select the messages you want to archive. In classic Outlook for Microsoft 365 on Windows, click once in the message list and press Ctrl+A to select the items in the current folder. In new Outlook for Windows and Outlook on the web, click in the message list and use Ctrl+A if available, or select the checkbox at the top of the list. If a page or batch limit applies, select the additional option to include all messages only when Outlook displays it and you truly want every matching item. On a Mac, click in the message list and press Command+A. Check the selection count or highlighted messages before moving on; do not assume that selecting one page has included older messages beyond it.
Use Archive, not Delete. In classic Outlook for Windows, go to Home > Archive on the ribbon. In new Outlook for Windows and Outlook on the web, select the Archive button in the toolbar; if it is hidden, open the more-actions menu and look for Archive. In Outlook for Mac, use the Archive button in the toolbar after selecting the messages. The exact toolbar layout can vary, but the action should be labeled Archive. Avoid Delete, which sends messages to Deleted Items instead of the Archive folder.
Let Outlook finish moving the messages. A large selection may take time, especially in a slow connection or a mailbox with many items. Keep Outlook open and watch for a progress indicator or updated message count. Do not repeatedly click Archive while the first operation is still running; repeated actions can make it harder to tell what has finished. For a very large folder, work in manageable batches if Outlook becomes unresponsive or reports that the operation cannot be completed.
Verify the result, then repeat for other folders. Open Archive and check that several expected messages are present. Return to the next source folder and repeat the selection and Archive steps if you want those messages moved too. When finished, use Outlook search or check the Archive folder’s message count to confirm the result. If you moved a message by mistake, open Archive, select it, and use Move to return it to its original folder or another suitable folder.

Common Mistakes

Assuming one selection covers the whole mailbox: Ctrl+A normally selects messages in the active folder or the current result list, not every message in every folder. Process each relevant folder separately, and confirm whether Outlook has selected all results or only the visible page.

Confusing Archive with Online Archive: The ordinary Archive command generally moves messages into the mailbox’s Archive folder. A company’s Online Archive is a separate storage area and may have different policies or access rules. Check the folder pane and your organization’s instructions before moving confidential or regulated mail.

Using Delete by accident: Delete sends selected messages to Deleted Items. They may be recoverable for a time, but that is not the same as archiving. Confirm the toolbar label before you click.

Leaving a search or filter active: A selection made while search results are displayed can apply only to those results. Clear the search when you intend to archive every message in a folder, or carefully verify the scope of the results first.

Tips

Start with one small folder or a few messages if you have never used the Archive command in this mailbox. Confirm where they appear, then continue with larger selections. This is especially useful when an account has both Archive and Online Archive folders.

For a large mailbox, archive one folder at a time and allow each operation to finish. This makes it easier to spot a problem and reduces the chance of Outlook timing out. If you need to preserve the original folder organization, consider creating matching subfolders under Archive and moving messages into them rather than putting everything into one flat folder.

Archiving is not the same as making an independent backup. The messages remain part of the mailbox and are subject to account access, retention rules, and mailbox policies. If you need a separate copy for safekeeping, use an approved export or backup method in addition to archiving, following your organization’s rules.

On classic Outlook for Windows, the Archive button may appear on the Home ribbon; in the newer Windows app, the toolbar can look different. Outlook for Mac uses Command+A rather than Ctrl+A for selecting all items in the active message list. In all versions, inspect the selection before acting, because keyboard shortcuts apply to whichever pane currently has focus.

Troubleshooting

Archive is missing or unavailable: Make sure you have selected messages rather than just the folder name. Expand the toolbar’s more-actions menu, or use Move and choose the mailbox’s Archive folder as a fallback. If the folder is absent, check that you are in the intended account and expand the folder pane. Work or school administrators may restrict folder actions, so contact your IT administrator if the destination is unavailable.

Only some messages moved: Check whether Outlook selected only the current page, visible results, or a subset such as unread messages. Repeat the operation for the remaining messages, or clear filters and select the full folder again. In large folders, batching the move can be more reliable than selecting everything at once.

The messages do not appear in Archive: Check the source folder’s message count and search for one of the moved subjects across the mailbox. Confirm that you are viewing the Archive folder for the same account, not a similarly named folder or a separate Online Archive. In desktop Outlook, allow time for synchronization; if the messages are visible in Outlook on the web but not in the desktop app, restart or refresh the desktop view and let it sync.

Outlook freezes or reports an error: Wait briefly to see whether the move completes. If it does not, restart Outlook, verify the mailbox connection, and try a smaller batch. Avoid repeating the same large action until you check whether some messages have already moved. If the problem persists, use Outlook on the web to test a smaller move or ask your mail administrator about mailbox limits and service issues.

Frequently Asked Questions

Does Archive delete my emails?
No. Archive moves selected messages out of the source folder into the Archive folder. They remain in your mailbox and can be found by searching or opening Archive.

Can I archive every message in Outlook at once?
There is not one Archive action that automatically processes every folder in the mailbox. Select and archive messages folder by folder. Within a folder, confirm that Outlook selected all items rather than just the visible page or search results.

Will archived messages still show up in search?
Usually, yes. Outlook search can find archived messages if the search scope includes the mailbox or Archive folder. If a message is missing, check the selected search scope and make sure the correct account is being searched.

Can I undo an archive?
You can move the message back. Open Archive, select the message, and choose Move, then select its original folder or another destination. Outlook may not restore it automatically to the exact folder it came from.

Is Archive the same as Online Archive?
No. The Archive folder is generally a folder inside your mailbox. Online Archive is a separate mailbox area available on some work or school accounts. The names and features can vary by account, so check with your administrator if you are unsure which one you should use.
