Sharing settings for files inserted from Google Drive
When you send a file to somebody by inserting files using Drive, Gmail checks to see if your recipients have access to the file and will prompt you to adjust the sharing settings on those files if they don’t.
When sending your message, if Gmail detects that your recipients don’t have access to your files, you’ll be given options to change your sharing settings. Here’s how it works:Sharing with 'Anyone with the link'
- They don't have a Google Account
- The email address they receive the message at is not associated with their Google Account
- They receive the email through a non-Google email list (Note: if you are sending the file(s) to a mailing list that is not a Google Groups mailing list, you will need to share to "Anyone with the link" instead.)
Aside from deciding who can access the file, you can also decide if they can edit, comment on, or just view the file. Learn more about access levels
Note that there may be files from Drive that you won’t be able to grant others access to. If this happens, Gmail will let you know and you may have to contact the original file owner to adjust the sharing settings.
Sharing options for Google Apps customers
If you’re a Google Apps customer, your domain's default setting might be different, but you will also have sharing setting options allowing people at [yourdomain.com] with the link to access the file, or you'll be able to share the file with your email recipients. You will be able to click More options to share the files with select recipients. With either option, users must be using a Google Account or Google Apps account to view the files.
