What Should I Do If I’m Having Trouble Sending Emails with Attachments?

If you’re experiencing issues when trying to send emails with attachments, there are a few potential causes and troubleshooting steps to help resolve the problem.

Troubleshooting Steps

1. Check Attachment Size

Most email servers, impose size limits on attachments. Check if the attachment exceeds the allowed size (often between 10MB to 25MB). If it does:

Compress the File: Use file compression tools (e.g., ZIP) to reduce the attachment size.
Use Cloud Storage: Upload the file to cloud storage (e.g., Google Drive, Dropbox) and share a link in the email instead.

2. Verify File Type Restrictions

Some email servers restrict certain file types (e.g., .exe or .bat files) for security reasons.

Rename the File: If your attachment is a restricted file type, try renaming the extension or compressing it into a ZIP file.
Check Security Policies: Contact your administrator or IP ServerOne support for any specific file type restrictions.

3. Ensure Stable Internet Connection

Large attachments can require a stable and fast internet connection to upload.

Switch to a Wired Connection: If possible, use a wired connection for better stability.
Avoid Peak Hours: Sending large files during times of high network traffic may slow the upload process.

4. Adjust Email Client Settings

If you’re using an email client like Outlook or Thunderbird, it might have limits or settings that affect attachments.

Increase Server Timeout: Go to your email client settings and extend the server timeout limit.
Check SMTP Settings: Ensure that your SMTP settings are correct. Incorrect settings can cause interruptions in the sending process.

5. Scan for Malware

Sometimes, antivirus software or email security filters may block attachments if they contain malware.

Run an Antivirus Scan: Check the attachment for any malware before sending.
Disable Attachment Scanning Temporarily: Some antivirus programs may block outgoing attachments. Temporarily disable attachment scanning if you trust the file is safe, and re-enable it afterward.

6. Contact Support

If none of the above steps work, contact IP ServerOne support at support@ipserverone.com for additional assistance, as there may be server-side restrictions or limits affecting attachment delivery.

⚠️ Important Note: Make sure that the recipient’s email server also supports attachments of the size and type you’re sending. Their server may have additional restrictions that could prevent the email from being received.
