    Hi Abdulaziz,

    Adding your domain to Microsoft Teams will not break your Google Workspace email, as long as you leave your existing email DNS records unchanged.

    Email routing across the internet is controlled entirely by your domain’s MX (Mail Exchange) records. As long as your domain’s DNS points its MX records to Google (smtp.google.com), all incoming email will continue to land in your Google Workspace inbox.

    While your regular emails will route to Google Workspace without issue, Microsoft Teams meeting invites sent from within Teams to internal colleagues may attempt to deliver to local Microsoft 365 mailboxes instead of Google.

    If you run into issues receiving Teams meeting updates in Gmail, you can configure dual routing or Exchange mail flow rules to route outgoing Microsoft mail to Google's servers.

    You can do so by following the guidance in this section: Integrating your business email with Microsoft Teams - Microsoft Teams | Microsoft Learn

    I hope this provides enough clarity and helps you stay inform with your current situation.

    Adding the domain to Teams for verification/sign-in does not affect current mail hosting by itself.

    Supported path:

    • When the domain is added for ownership verification, Microsoft verifies the domain and this doesn't involve DNS changes if registrar-based verification is used.
    • Manual verification typically uses a DNS record for verification only. Community guidance in the provided context states this is usually a TXT record and does not affect existing email service or website.
    • Email routing changes only when mail-related DNS records are changed, especially MX records.

    What does affect current Google-hosted mail:

    • If the setup is completed with the option that connects email so that mail is delivered through Microsoft 365, then email sent to and from the domain will be delivered through Microsoft 365.
    • If the goal is to keep Google as the current mail host and only integrate Teams/calendar, the setup uses the third-party email integration flow instead of switching mail delivery.

    Practical summary:

    1. Add domain + verify ownership: safe for current Google mail hosting.
    2. Do not change MX/mail DNS records unless the intention is to move mail flow to Microsoft 365.
    3. If using Google Workspace with Teams, follow the option to connect another provider and the calendar integration steps rather than the Microsoft email delivery option.
