Question

mail inbox empty when I sign in on outlook

Z 0

I have two gmail accounts I use. I signed into my primary account, but my inbox is empty. I signed into the other account, and everything works fine. I use the primary Gmail account as my Microsoft account as well. That is the one I cannot access on Outlook. I logged into my Microsoft account and went to the "mail section" and the account there has just a bunch of letters and numbers for a name. Basically, I do not know that account and cannot edit it either. I have signed in and out repeatedly and made my Gmail account the primary account multiple times.

Answer 1

Signing in to Microsoft with a Gmail address does not open the Gmail mailbox; add that Gmail account separately to the Outlook app, or use Gmail directly if you are using Outlook.com in Edge.

Your Gmail address is currently acting as a Microsoft account alias—a username for the Microsoft account—not as a connection to Gmail messages. Changing it to the primary alias therefore does not import or display the Gmail inbox. Microsoft no longer supports adding a Gmail mailbox directly to the Outlook.com website.^1^

On Outlook for Windows

If you use new Outlook:

Open Outlook.
Select View → View settings. Alternatively, select File → Account info.
Open Accounts → Your accounts.
Under Email accounts, select Add Account.
Enter the primary Gmail address and select Continue.
Complete the sign-in on the Google page and grant Outlook permission to access the mailbox.
After it appears under Email accounts, select Manage beside it → Set as primary account.

The Gmail folders and messages should then appear in Outlook’s folder pane.^2^

If you use classic Outlook—identified by a File tab:

Select File → Add Account.
Enter the Gmail address and select Connect.
In the Google sign-in window, verify that the correct one of your two Gmail accounts is displayed.
Enter its Google password.
On the Google permissions page, select Allow, then Done.^3^

Because the other Gmail account already works, carefully check the Google account shown during authorization; Outlook must be authorized against the primary Gmail account, not merely signed into the Microsoft account that uses the same address.

If you are using Outlook.com in Microsoft Edge

The Outlook.com website cannot currently aggregate a Gmail mailbox. Use one of these instead:

Open the primary mailbox through Gmail’s website.
Install/use Outlook for Windows and add Gmail using the steps above.
Use Outlook for iOS or Android, which can display multiple mailboxes together.^1^

About the letters-and-numbers address

An address resembling outlook_[letters-and-numbers]@outlook.com is a Microsoft-generated Outlook identity associated with an account registered using a third-party address such as Gmail. It is not the Gmail mailbox and will not contain Gmail messages unless mail was separately delivered to that Outlook.com mailbox. Microsoft documents this generated-address behavior for Outlook for Windows.^4^

Since repeatedly signing out and changing the primary Microsoft alias has not helped, no further alias changes are needed to retrieve Gmail. The required change is to add the address specifically as a Google/Gmail mail account inside the Outlook app.

If Gmail is already listed under Outlook → Settings → Accounts → Your accounts but remains empty, remove it from this device only, then add it again and complete Google’s permission prompt. Do not choose Remove from all devices; Microsoft warns that this can remove Microsoft Cloud data across Outlook clients.^2^

I believe there may be some confusion between your Microsoft account and your Gmail mailbox. Microsoft allows you to use a Gmail address to sign in to Microsoft services, but this does not automatically connect your Gmail inbox to Outlook.com. In fact, Microsoft has discontinued support for synchronizing third-party email accounts directly through Outlook.com. The unfamiliar address containing letters and numbers may also be an automatically generated Outlook address associated with your Microsoft account, which Microsoft has documented in certain configurations. Could you please confirm whether you are accessing Outlook.com through your browser or the Outlook application installed on Windows 10? Also, can you still see all your messages when signing in directly at https://mail.google.com using your primary Gmail account?

If your messages are available through Gmail, you are simply accessing a different mailbox. If you want to manage your Gmail messages through Outlook, I recommend using the Outlook application for Windows rather than Outlook.com. In New Outlook, navigate to Settings > Accounts > Your accounts > Add account, enter your Gmail address, and follow the Google authentication prompts to connect the mailbox. Microsoft provides the official instructions here: https://support.microsoft.com/outlook/getstarted/add-a-gmail-account-to-outlook-for-windows.

Thank you for responding. I do understand that Gmail accounts are different from Microsoft accounts. I just mentioned that because I used my primary Gmail account as an alias for my Microsoft account. I am using the Outlook app and I have added both my gmail accounts using the same regular procedures. The issue is I can see my mails on only one of those accounts; the other is completely empty. I am able to access it using https://mail.google.com/so I do believe it’s a mailbox issue. I just do not know how to fix it since i cannot edit the automated Outlook address and adding that particular Gmail account to Outlook seems not to be working. I have removed both accounts and added them back and still got the same results.

The problem appears to be with how Outlook is connecting to or synchronizing the affected account, rather than with the Gmail mailbox itself. Because that Gmail address is also registered as a Microsoft account, Outlook may be recognizing it as a Microsoft identity instead of establishing the intended Google mailbox connection. Could you please confirm whether you're using New Outlook or Classic Outlook? Also, when adding the affected Gmail address, does Outlook redirect you to Google's sign-in page to authorize mailbox access, or does it ask you to sign in through Microsoft? This distinction is important because the same email address can represent two separate account identities.

As an additional check, if you're using New Outlook, open Settings > Accounts > Your accounts and examine how the affected account is listed. Does it display your actual Gmail address, or the automatically generated Outlook address containing letters and numbers? If the account is being configured as a Microsoft account, the next step would be to establish the connection specifically through Google's authentication process rather than changing your Microsoft account aliases again. Microsoft documents the supported Gmail configuration here:

I'm currently having the same issue. I'm using the new outlook, I've tried everything that you said and nothing appears to be working. I've made sure to update outlook and everything and it's not making any difference. They still appear in my gmail inbox. And yes, outlook redirects me to Google's sign in page, and I set the account as the primary account in outlook, still nothing.

I hadn't opened my email on my laptop since I last sent in the question. I just opened Outlook, and surprisingly everything seems to be working now. Fingers crossed it stays working. Thanks for the help.
