Hi @C. Sheena
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, it's likely you asked how to link to a specific email in Outlook so you can reference it in tools like To Do or Word. Here’s some suggestions you can try:
- Open the email in Outlook Web (OWA)
When you open an email in a separate window or tab, the URL in your browser is the direct link to that email. Copy that URL and paste it wherever you need (e.g., in a Word doc or To Do task). Note: This works only if you and the recipient have access to the same mailbox and are signed in to the same account
This is done through the Microsoft outlook API which leverages MS Graph API. So if you are looking to do anything like that, I suggest looking into that Outlook mail API overview
Essentially, when you open an email in Outlook Web, the link about is the direct link to the email. Also, MS Graph gives you this if you pull it.

2.Alternative for Quick Access
If you just need to reference an email in another email or document:
- In Outlook desktop, use Insert > Outlook Item to attach or link an email to another message
