Teams Webinars: Org name vs brand name – how are people handling this?

Has anyone else hit this with Teams webinars?

Microsoft recently changed how webinar emails are sent, and the sender name now seems to come from the tenant Organisation Name. You can change that in M365 admin, but that’s where the problem starts.

In a lot of companies, the organisation name is a legal/billing entity, not the public-facing brand.

Example:

• Legal / tenant name: FedEx Corporate Services, Inc.
• Brand: FedEx

Teams webinar emails now go out showing the legal entity, which isn’t great for external, customer-facing events. Changing the org name just to fix webinar emails can have knock-on effects for billing, contracts, and governance.

As far as I can see:

• No way to set a brand-specific sender name
• No per-webinar or per-mailbox sender identity
• Org name is global and used across multiple services

The only real workaround seems to be not using Teams-generated emails at all, and sending custom emails via Power Automate / Graph / a marketing platform, while still using Teams for the actual event.

Curious how others are dealing with this:

• Are you just living with it?
• Changing the org name with legal sign-off?
• Or bypassing Teams emails completely?

Feels like a gap for larger, multi-brand orgs.
