Hello @Kim Austen,
Thank you for reaching out and sharing the details of your issue.
To help investigate this further, could you please confirm a few details about your setup:
- Are you using a personal Microsoft account (e.g., Outlook.com, Hotmail) or a work/school account provided by your organization?
- Are you sending the invitations from the Teams desktop app, web version, or mobile app?
- Is your Teams account linked to an external email provider (e.g., Gmail, Yahoo), or is it using a Microsoft-hosted domain?
- Do you have multiple email aliases associated with your account?
- Have recipients confirmed that their replies are bouncing or not reaching you?
If possible, could you share an example of the “strange Outlook address” that appears in the invitation?
I think what you mean is that your invitee should have received your invitation, but the email address shown is a virtual Outlook address, a randomly generated combination of letters and numbers with the domain outlook.com.
This typically happens when you're using an email address with a third-party domain name (e.g., Gmail, Yahoo). Microsoft Teams converts it into a virtual Outlook address when sending invitations. As a result, invitees cannot reply to that email, and you won’t receive reminders or responses.
Please provide the above details so I can better understand your environment and offer the most accurate guidance.
Looking forward to your response.
