How to combine inboxes in Outlook
Outlook on Mac and on your phone has an All Accounts view. Outlook on Windows has never had one, despite a decade of people asking. These are the workarounds that actually work, and where each one falls down.
The four methods
1. Saved search across all mailboxes
Click the search bar, switch the scope from Current Mailbox to All Mailboxes, search something like received:(this week), then save it to Favourites.
Works because: No macros, no security prompts, nothing to install. Two clicks to set up.
Falls down: The saved search often reverts to Current Mailbox when you reopen it, so you re-select the scope every time. It is a snapshot, not a live view.
2. VBA macro button
Paste a macro into the Outlook VBA editor that runs an all-mailbox search, then pin it to the Quick Access Toolbar as a one-click button.
Works because: Closest thing to a real unified inbox on Classic Outlook, and you can filter to unread or this week.
Falls down: Doesn't exist in New Outlook — macro support was removed. Needs macros enabled, which Microsoft itself warns against. Doesn't auto-refresh: new mail won't appear until you click again.
3. Rules that copy everything into one folder
For each account, add a rule that moves or copies incoming mail into a single folder.
Works because: A genuinely live, always-current combined view. Works in any Outlook version.
Falls down: Replies go out from the account holding that folder, not the address the sender wrote to. Duplicates eat storage, and you lose the per-account structure some people want to keep.
4. Add every account to your phone
Outlook mobile has a real All Accounts inbox.
Works because: Free, and it actually works.
Falls down: Only on the phone. The desktop problem is untouched, and replying from the right address is still fiddly.
Which one should you use?
Two or three accounts and you mostly want to glance at what’s new: use the saved search. It costs nothing and you can set it up in a minute.
On Classic Outlook, checking constantly, comfortable with macros: the macro button is the best of these. Just know that it disappears the day you move to New Outlook.
More than a handful of addresses, especially across different domains: none of these solve replying. That is usually the point where the workarounds stop being worth it.
The part none of them fix
Every method above answers “how do I see everything.” None answers “how do I answer everything from the right address.” Copy mail into one folder and your reply goes out from that account. Run a macro and Outlook still guesses the sender.
If you run several products or clients, that is the expensive half: a customer who wrote to support@productA.com gets an answer from your personal address.
How we approach it
All Your Inboxes works outside the mail client, so it behaves the same in Classic Outlook, New Outlook, Gmail or on a phone. Each mailbox forwards a copy to us. New mail becomes a notification at the address you already read, tagged with which project it belongs to.
Reply to the notification and the answer leaves through the original mailbox’s own server — right address, same thread, no sign of us. Your Outlook setup is untouched: no macros, no rules, no merged folders. Turn it off and nothing has changed.
