What will happen with a Microsoft account with an alias using Outlook 365 for the primary alias & Outlook.com for an additional alias?

    Hi Diane805,

     

    I have several alias accounts, and they converted over without any issues.

      Teresa,

       

      I posted a question regarding the use of an alias on 10-02-23 to which you replied 10-09-23.

       

      I have a problem with the Mail app which I believe is related to my use of an alias. Last night, I was using the Mail app (the envelop icon) on my Surface and noticed that my Outlook.com email account no longer appeared. Only my Gmail account was showing up. The Outlook.com email address is my alias. The Mail version was 16005.14326.21624.0. Previously both the Outlook.com account and the Gmail account appeared on this app. However, I went to the web version, outlook.live.com, on the same computer, both the Outlook.com account and the Gmail account were still there.

       

      This morning I tried again on the Surface with the Mail app. It still shows only my Gmail account. However, the Mail version is now 16005.143263.21632.0. Both email accounts are still shown on the web version outlook.live.com.

       

      In the past, the Mail app and the outlook.live.com version showed the same thing. Now they don’t.

       

      I tried to add my outlook.com email address as a new account, but I got an error message saying “Account already exists. There’s already an account set up to use ***.***” (my email account to which the alias is related).

       

      I have screen prints from last night & today. My questions are:

       

      1. What happed to my outlook.com email account on the Mail app?
      2. How can I get my outlook.com account back on the Mail app?

       

      I look forward to your reply.

        Diane805 Hi,

        If I understand your problem correctly, then analyze this step below:

        "

        Are you sure? If you remove an alias that's an email address from a Microsoft domain (like @hotmail.com, @live.com, @outlook.com, or @msn.com), you're permanently deleting the alias and it can't be associated with any Microsoft account again.

        If you're removing a primary alias, you'll need to choose another primary alias before it can be removed.

        If you remove an email address from a non-Microsoft domain (like @gmail.com), then it usually becomes immediately available to be added as an alias on another Microsoft account.

        If you want to remove a connected email account, read Remove a connected account from Outlook.com."
