September 2025
Starting October 2025, Google Classroom will no longer support sending out-of-domain (or trusted domain) email invites to students directly. Please note that for trusted domains, both the sender's and recipient's domains must trust each other.
This means that while you can still invite out-of-domain users to your courses as students, Google Classroom will no longer automatically send an email invitation on your behalf from noreply@classroom.google.com.
We've provided additional information below to guide you through this change.
Key changes:
Starting October 2025, the option to invite out-of-domain users as students via email will be removed. If you attempt to send an email invitation to an external account, you will receive the following error message:
"You've added an external email. You can only send to addresses within your organization or to admin-approved accounts. Alternatively, share the invite link."
If you attempt to invite out-of-domain users to a course via the Classroom API's courses.students.create or courses.teachers.create endpoints, you will receive a PERMISSION_DENIED.CannotInviteUserInUntrustedDomain error.
Potential impact:
Out-of-domain users will no longer receive a course invite email directly from Google Classroom.
What you need to do
No action is needed from you regarding this change. You can still invite out-of-domain users to your courses by manually sharing a course invite link or a class code with them.

Upcoming changes to third-party cookie requirements in Google Drive
What's changing
Google Chrome and other browsers have begun phasing out third-party cookies in order to better protect user privacy. Starting January 2, 2024, Drive will start serving downloads without requiring third-party cookies.
If you have specific workflows in place that rely on Drive's download URLs or use an app which relies on Drive's download URLs, you'll need to switch to the Drive and Docs publishing flows by January 2, 2024. Specific instructions are below.
Why it's important
Serving downloads without requiring third-party cookies will work to improve usability, security, and privacy for Drive users.
Additional details
Learn more about how to audit your code to look for third-party cookies and what action you can take to ensure you're all set for the end of third-party cookies here.
End users and developers:
Use an iframe (HTML element that loads another HTML page within the document) on your website to load the content. You can do this by going to the file in Drive and taking the next relevant step:
- For Workspace files (Google Docs, Sheets, Slides, and Forms file types) use the Google Docs publishing URL of the file.
- For other files, once opened in Drive, select "Open in new window" from the overflow menu, and then open the overflow menu and select "Embed item...", which provides the iframe HTML tag.
Rollout pace
Switch to the Drive and Docs publishing flows by January 2, 2024
