Microsoft Teams: Guest invitation emails will be sent from the inviter’s email address

Microsoft Teams guest invitation emails will soon be sent from the inviter’s email address instead of a no-reply address, improving clarity and enabling direct replies. This change, rolling out worldwide from late June to late July 2026, requires no admin action but users should be informed. What and Why We are updating how Microsoft Teams sends guest invitation emails to improve clarity and trust in cross-tenant collaboration. Instead of being sent from a Microsoft no-reply address, guest invitation emails will soon appear to come directly from the inviter’s email address. This change helps recipients easily recognize who invited them, enables direct replies, and reduces confusion, improving the overall collaboration experience. Rollout Schedule General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out in late June 2026 and expect to complete by late July 2026.
