Welcome to the Microsoft Q&A forum.
Thank you for reaching out, and I’m really sorry you’ve been running into trouble sharing your mailbox. I know how important it is to keep your email accessible to the right people.
To get a clearer picture and guide you accurately, I’d like to get a better sense of what’s happening on your side. When you mentioned that your main Microsoft 365 email cannot be shared with “other emails attached to it,” this can point to a few different scenarios. Understanding which one fits your situation will allow me to guide you with the exact steps you need.
To narrow things down, could you let me know which of these options matches your case?
- Sharing the entire mailbox with another user
- Sharing specific folders (such as your Inbox, Sent Items, or custom folders)
- Allowing someone to send emails on your behalf or as you
- Accessing or sharing a shared mailbox
- Using Microsoft 365 directly from Microsoft or through a provider like GoDaddy
Each scenario works a little differently, and once I know which one applies, I can walk you through the right solution.
If you prefer speaking with someone directly, you also have the option to request a call from Microsoft Support. To do this, please do these steps, a support agent will reach out to you directly:
- Sign in at Microsoft 365 admin center
- Go to Support > Create a support request
- Select Request a call
However, if your Microsoft 365 subscription is managed through GoDaddy, certain mailbox-sharing features are handled differently. In that case, you can reach GoDaddy’s 24/7 Microsoft 365 support team here: GoDaddy Global Support | Contact Us - GoDaddy
