Joining classes

Teachers can't send an invitation to certain students

Teachers can't invite students from an untrusted domain to join a class. For details, go to Use an allowlist for trusted domains.

Some students couldn't use the class code to join a class

If students are from a domain that's not on your allowlist, they can't use a code to join a class in your domain. For details, go to Use an allowlist for trusted domains.

File sharing

Teachers can't share a file with the class

If a domain is on your allowlist, you still need to give your users permissions to share outside of your domain. For details, go to Grant file sharing access for domains on your allowlist.

Students can't turn in files for an assignment

If students can't submit their work:

• Contact the Google Workspace for Education administrator for the students from domains on your allowlist and check that they can share files outside of their domains. For details, go to Grant file sharing access for domains on your allowlist.
• Check that the teacher has space in Google Drive. Learn how to clear Drive space and increase storage.

Students can't unsubmit their files for an assignment

If a student can't unsubmit their work for an assignment, you might need to give them permission to share outside of your domain. For details, go to Grant file sharing access for domains on your allowlist.

Teachers can't return files to their students

If a teacher in your domain can't return student work for an assignment, you might need to give your users permission to share outside of your domain. For details, go to Grant file sharing access for domains on your allowlist.
