Solicitor Email Attachment Error
Why Legal Email Attachments Fail — And How to Fix Them
Email attachment errors between solicitors and clients are more common than you’d expect. Legal documents like contracts, deeds, and court filings are often large, password-protected PDFs — triggering filters on both ends. Here’s how to diagnose and fix the problem.
Common Causes
| Cause | Who It Affects | Severity |
|---|---|---|
| File size exceeds limit (usually 10–25 MB) | Sender | High |
| Antivirus/spam filter blocks PDF | Recipient | High |
| Password-protected PDF rejected | Both | Medium |
| Blocked file extension (.exe embedded) | Recipient | Medium |
| Outlook/Gmail policy restrictions | Both | Low |
Fix 1 — Use a Secure File Sharing Link Instead
Most modern solicitor firms use portals like Sharepoint, Dropbox, or case management portals to send large documents. Ask your solicitor to share a download link rather than attaching the file to the email.
Fix 2 — Compress the PDF Before Sending
ilovepdf.com — free online PDF compressor
Adobe Acrobat — File → Reduce File Size
Smallpdf.com — drag-and-drop compression
Fix 3 — Whitelist the Solicitor’s Email Domain
If your spam filter is blocking the attachment, add your solicitor’s email domain to your safe senders list in Gmail or Outlook settings. This prevents legitimate legal emails from being quarantined.
Fix 4 — Ask for a Different Format
Request that the solicitor send the document as a non-password-protected PDF, or use a .docx file if the document does not need to be in final form. Many email filters reject encrypted or password-locked attachments automatically.
Never open unexpected email attachments claiming to be from a solicitor without verifying by phone first. Solicitor impersonation emails are a common scam.
