    Hi Mark,

    This is April, I'll be happy to assist you. Sorry to hear that you're having issue with Microsoft account email address. Let me help you out.

    Based on the description of the issue you provided, you're trying to add three email accounts to Outlook that are linked to your Microsoft 365 subscription, but you're having trouble finding the option to do so.

    Are the three email addresses you want to add all Microsoft 365 accounts under the same organization, or are they a mix of different providers (like Gmail, Yahoo, or another domain)?

    How to Add Multiple Email Accounts in Outlook (Microsoft 365)

    1. Open Outlook
      • Launch the Outlook desktop application on your Windows PC
    2. Open Account Settings
      • Click File in the top-left corner, then select Account Settings > Account Settings from the dropdown menu.
    3. Add a New Email account
      • Under the Email tab, click New.
      • Enter the email address you want to add (such as a second or third Microsoft 365 account).
      • Outlook will automatically detect the server settings. When prompted, enter the password.
    4. Repeat for Additional Accounts
      • Repeat the same steps for each email address you want to add.
      • Each account will appear separately in the left navigation pane with its own Inbox, Sent Items and folders.
    5. Set a Default Account (Optional)
      • In Account Settings, select the account you want to use by default.
      • Click Set as Default.
      • This account will be used automatically when you create a new email.
    6. Verify Send/Receive Settings
      • Go to File > Options > Advanced > Send/Receive
      • Confirm that all accounts are included so Outlook syncs them properly.

    If all the email addresses belong to the same Microsoft 365 tenant, Outlook will usually configure them automatically. However, if one of the accounts is external such as Gmail or Yahoo you'll need to enter the IMAP and SMTP settings manually. Outlook also supports multiple accounts at the same time, so you can add and manage as many email addresses as you need side by side.

    I hope this helps. If you need further assistance you can reply to this message.

    Thank you,

    April P.

    Are you trying to add three email addresses as alias to your Microsoft account.

    OR

    Are you trying to add three different email addresses to your Outlook Classic email app?
