If you are unable to send emails with large file attachments, here are a few things you can do:

1. Resize the file



Reduce the size of the file to a more manageable size.

2. Set up FTP access



Set up File Transfer Protocol (FTP) access, which will allow you to send larger files over the web.

3. Upload the file to a cloud storage solution



Upload the file to a cloud storage service, and provide a link or access credentials in your email.

4. Utilize a file-sharing service



Consider using a file-sharing service to send large files securely, as they typically have large file size limits.
