Wrong email address

Question

I'm using Home.com and trying to send emails to clients. the wrong email is embedded into the email slot and I have called Homes.com to correct it, they said it's an Outlook issue not there's that they don't even have that email address in their system

Answer 1

Homes.com is likely using the email address that Outlook.com/your Microsoft account is presenting as the “From” or reply address. When the wrong address is embedded, it is usually caused by one of these Outlook/Outlook.com issues:

1. Outlook.com account/alias problem

• If the Outlook.com account has multiple aliases, a different alias (or a 3rd‑party address) may be set as the primary alias.
• In that case, outgoing mail can appear to come from the wrong address, and external systems (like Homes.com) will see and embed that address.
• To fix this, sign in to Outlook.com in a browser and check the account aliases and which one is primary. Make sure the correct email address is set as the primary alias and used as the default “From” address when composing mail.

2. Outlook profile or multiple accounts issue

• If using classic Outlook for Windows with multiple accounts in one profile, messages can be sent from or associated with the wrong account.
• The documented fix is to remove and re‑add the secondary account in the Mail control panel so Outlook correctly associates messages with the right mailbox:
  1. In Outlook, move any mis‑sent messages into the correct folders.
  2. Close Outlook.
  3. Open Control Panel → search for Mail → Mail Setup → E‑mail Accounts.
  4. Select the secondary account that is getting messages incorrectly and choose Remove.
  5. Close the dialog, then re‑add that account via E‑mail Accounts → New and complete setup.
  6. Send a test message and confirm the correct address now appears.

3. Outlook.com “wrong address” behavior

• Outlook.com can show or send from an unexpected address if the Microsoft account was created with a 3rd‑party email or if aliases are misconfigured. This can cause recipients (or integrated services) to see an address like outlook_[numbers]@outlook.com or another unexpected address.
• The workaround in such cases is to configure the mailbox directly as an IMAP/POP account in Outlook, using the correct server settings, so the right address is used for sending.

Given Homes.com reports they do not have that wrong email in their system, the most likely cause is Outlook/Outlook.com presenting the wrong From/reply address due to aliases or profile configuration. Correcting the primary alias/default From address in Outlook.com, or recreating the Outlook profile/account as described, should stop the wrong email from being embedded.
