Extract, save and remove email attachments,
or export emails in various formats to disk
with this Outlook Add-In!

Outlook Attachment Sniffer is a powerful Add-In for Microsoft Office Outlook to extract specific or all attachments and to export emails from your Outlook in various formats!

Exported attachments can be replaced with links to the saved files, and you can reimport them later. When replying or forwarding emails, these links can be replaced automatically with the original files.

You also can copy and move emails to other Outlook folders, optional with auto-creation of subfolders depending on the email's data (subject, sender, recipient, date and so on).

Improving performance

My Outlook PST-files
and Exchange-files
are growing and growing...
What can I do?

How can I save and remove all attachments from Outlook...?

How can I export all emails from Outlook
in bulk...?

By extracting attachments you often can - sometimes dramatically - reduce the size of your Outlook PST-files and Exchange-files.

Shrinking or compressing your PST- and Exchange-files usually will improve the performance of Outlook, and will result in a more efficient work with Outlook!
