Hello, I'd like to create 2 aliases on our work email, maintaining the company's domain. Is there a possibility of doing so? I aim to categorize emails received for my colleague or for me, and maybe filter them to separate folders. I would like to provide people with an email containing my name or my colleague's name, even if they arrive in a common inbox. I tried to follow some online instructions of the sort:
Sign in to your Outlook account.

  1. At the top right, click on your user picture.
  2. Click on My profile.
  3. Under Account information, click on Edit account info.
  4. Under Account aliases, click on Add an email address.

But when I do that, i don't see those options.

Thanks in advance for your time and help

    Dear @Marco,

    I understand your confusion. What you are trying to do is supported for business (Microsoft 365) accounts; however the steps you followed apply only to personal Outlook.com/Microsoft accounts, which is why those options do not appear for your work email.

    For work or school accounts, email aliases cannot be created by the user from Outlook settings or the “My profile” page. Aliases must be added by a Microsoft 365 administrator through the Exchange Admin Center.

    Note: If you do not know who your IT admin is, you can refer to this Microsoft Official Guide here: How do I find my Microsoft 365 admin?

    Your Microsoft 365 admin can add multiple email aliases (for example, one with your name and one with your colleague’s name) under the same company domain and have all emails delivered to a single mailbox. For more information and instructions, please refer to Add another email alias for a Microsoft 365 business subscription user

    Moreover, if this inbox is intended to be used by both you and your colleague, you may want to consider using a shared mailbox. With a shared mailbox, both of you can access the same inbox directly from your own Outlook accounts, while emails are sent to a single shared address. For more information: Create a shared mailbox and Open and use a shared mailbox in Outlook

    A shared mailbox can also have multiple aliases (for example, one with your name and one with your colleague’s name), all using your company’s domain. This allows external senders to email either of you by name, while messages are delivered to the same inbox. You can then use Outlook rules to organize emails into separate folders if needed.

    Please note that shared mailboxes and aliases must be created by a Microsoft 365 administrator. If you do not have admin access, I recommend contacting your IT administrator to set this up for you.

    I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

    The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

    Thank you for your patience and understanding. I'm looking forward for your reply.

    Yes, this is possible, but only a Microsoft 365 admin can create aliases for a work account, and it is done in the Microsoft 365 admin center, not from the personal “Account aliases” page.

    For a work account using Outlook on the web:

    1. Ask the Microsoft 365 admin in the organization to add aliases to the shared/common mailbox (or to the user mailbox) in the admin center:
      1. Go to Users > Active users.
      2. Select the mailbox (user) that should receive the emails.
      3. Under Aliases, select Manage username and email (or Edit next to User name / Email).
      4. In the Alias or Username box, type the new alias (for example, ******@company.com and ******@company.com) and choose the correct company domain from the drop-down.
      5. Select Add, then Save changes.
      6. Wait up to 24 hours for the aliases to become active.
      All mail sent to any of those aliases will arrive in the same mailbox (the common inbox), so rules in Outlook on the web can then be used to move messages to different folders based on the To address.
    2. After aliases are created, configure rules in Outlook on the web:
      1. Open Outlook on the web.
      2. Go to Settings (gear icon) > Mail > Rules.
      3. Create a rule like: If the message was sent to ******@company.com, move it to folder “Marco”; and another rule for the colleague’s alias.

    Notes:

    • For Microsoft 365 business accounts, the “Account aliases” page used for personal Outlook.com/Microsoft accounts is not used to manage work email aliases; that is why those options are not visible.
    • Up to 400 aliases can be created per user, and all will deliver to the same mailbox.
    • By default, when replying from Outlook desktop, the primary email address is used; Outlook on the web can be configured (by the admin using Set-OrganizationConfig -SendFromAliasEnabled $true) to allow sending from aliases.
