How to add the 'All Accounts Inbox' in Outlook for Windows 11

Hello Cian

Hi, I'm Karl and will be happy to help you today.

Outlook for Windows has never had a <Unified Inbox> regardless ot the verson of Outlook or Windows.

The only way to have all email accounts deliver emails to the same <Inbox> would have been if the accounts were configured as POP accounts which allows for POP accounts to the same PST file to deliver to a single <Inbox>.

IMAP & Exchange accounts will always have their own <Inbox> folders and that cannot be changed.

Is this Windows 11 system a new machine by chance and you configured the accounts in Outlook by just entering the email address / password for the email accounts? The would result in Outlook configuring the account(s) using IMAP (or Exchange if applicable) by default.

To see how you accounts are configured, from within Outlook, o to

<File> --> <Account Settings> --> <Account Settings> --> <Email> tab

If you still have your Windows 10 system with Outlook installed, would do the same and compare how the accounts are configured

2025 and we still can't have a unified inbox on Windows

With all due respect, this has to be the most stunningly disqualifying response to an extremely intuitive, 1 of the most basic use cases expectation.

Above statement not addressed personally to Karl, but rather to product management & user experience teams @ Microsoft.

Seriously, I’m incredulous & makes me wonder esp if the user experience team even spends any time gathering information regarding everyday use patterns

OR

they just spend time in isolated conference rooms talking amongst themselves for what should be according to them highest priority gadgety bells & whistles?!?

As said above: This serious deficiency makes the product totally disqualified for any meaningful usage, & on Windows 10 I’m switching back from “New Outlook Preview” to older & clunkier looking “Mail & Calendar”

It would be an understatement to express how disappointed & shocked I’m regarding this issue in this advanced day & age of August 2023.

100% agree. It seems like such a massive oversight, and it is something that, as demonstrated my android, iOS, and MacOS, is entirely feasible.

I would also like this feature...being able to combine my two school accounts into one is the reason I still use the Windows "Mail" client instead of Outlook. Ridiculous that they haven't implemented this already.
