Email attachment too large to send, keeps bouncing back
The file is bigger than your email service allows, or bigger than the recipient's email system accepts. Compress the file to make it smaller, split the files across multiple emails, or use a file-sharing service instead. Most email services limit attachments to 20-25 MB, but some corporate systems are much stricter.
Email servers have size limits to prevent abuse and keep their systems running smoothly. If your attachment is over that limit, the server rejects the email before it even reaches the recipient. We'll check your file size, compress it if possible, or move you to a better way to share the file.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
Skip — I just want a technicianCommon mistakes to avoid
- Assuming the problem is your email service when it is actually the recipient's email server that is stricter
- Trying to compress already-compressed files like PDFs or JPEGs - they will not get much smaller
- Attaching multiple large files instead of moving them all to one folder on Google Drive or OneDrive
