Outlook Attachment Extractor Screenshot.
The Outlook Attachment Extractor opens a saved .PST or .OST mailbox and writes every file attachment to a folder on your disk. Choose folders or messages, filter by extension, and extract the files in one run. There is no Outlook or add-in to install. It reads .PST and .OST archives directly, including an old backup or an orphaned offline cache on a PC that never had Outlook.

How to download and use Outlook email attachment extractor software

Open the PST or OST.
1

Open the PST or OST

Click Open or drop a single .PST or .OST file into the program. The folder tree loads on the left, and the message list shows the attachment count next to each email.

Pick folders or messages.
2

Pick folders or messages

Check the folders you want or switch the source to selected messages. A text filter on the subject line or sender narrows a large mailbox to what you need.

Set the extraction options.
3

Set the extraction options

Filter by file type, keeping only PDF, DOC, XLS, images, or ZIP. Skip tiny signature logos below the size you set, drop duplicate files by content, and choose how same-name files are handled.

Extract to a folder.
4

Extract to a folder

Choose an output folder and click Start. Save files in the PST folder structure or flat, name them as the original or Date_Subject_Name, and add an optional CSV report of everything written.

Pull every attachment in one pass.

Pull every attachment in one pass

Hours of clicking, gone. A full mailbox turns into a folder of real files in minutes, instead of an afternoon of Save As. Point the Outlook Attachment Extractor software at a 10 GB archive and it clears the whole mailbox in one run, with no Outlook and no add-in to set up.

Real documents, not signature logos

A folder you can actually use. Open the output and every file is a real document, not the hundreds of tiny logo images that ride in email footers. That is the difference between attachments you can hand straight to accounting and a folder you have to weed by hand.

Real documents, not signature logos.
No duplicate copies.

No duplicate copies

The same file, saved once. Attachments are de-duplicated by content, not by name. When the same PDF rides along on 30 replies in a thread, you get one copy instead of 30, so the output folder stays clean. If it is the messages themselves that are doubled up, not just the attachment, an outlook duplicate remover clears those out of the PST first.

You decide on name clashes

Nothing overwritten by accident. When two files would collide, you choose to skip, overwrite, or auto-number the copy, so an important attachment is never quietly replaced by a later one. What lands on disk is exactly what you meant to keep.

You decide on name clashes.

Saving attachments by hand means opening each email and clicking Save As one file at a time. Outlook's Save All Attachments is often greyed out or bundles everything into a zip. Online extractors ask you to upload a mailbox full of private mail to someone else's server. The Outlook Attachment Extractor reads the archive locally and works through a 50 GB file in a single pass, leaving a clean folder of files in minutes without signature logos or duplicate copies.

Folder tree with an attachment count

The left pane shows the .PST or .OST folder structure. The message list adds an Attachments column, so you can see which emails carry files before extraction.

Filter by type and size

Keep only the extensions you need and set a minimum size, such as 20 KB, to drop signature icons. A text filter narrows a large mailbox to the messages that matter, and you can add extensions beyond the common office and image formats.

Naming, structure, and a CSV report

Save files under their original names or a Date_Subject_Name pattern, and mirror the mailbox folder hierarchy or write everything flat. A CSV report lists every extracted file and where it went.

Who reaches for Outlook email attachment extractor software

Legal and eDiscovery

Pull documents out of a custodian's .pst without loading the whole mailbox into a review platform. Folder selection keeps the export inside the matter, and the CSV report logs what was collected.

IT and migration

Harvest attachments from a departed employee's .pst or an orphaned .ost left behind when a mailbox is gone. It needs no Exchange connection or Outlook profile.

Accounting and back office

Collect years of invoices and contracts from a shared mailbox into dated folders, de-duplicated and ready to file. Statements can then go a step further once they are on disk, and convert bank statements into a spreadsheet.

Frequently Asked Questions

Yes, a whole folder or a hand-picked set of messages in one go. Tick the folders in the tree or switch the source to selected messages, and the Outlook Attachment Extractor software writes every attachment to your output folder in a single pass.

Open the .pst or .ost, tick the folder you want, such as the Inbox or Sent folder, and run the extraction. Every file attachment in that folder is saved to disk, optionally filtered by type and mirrored into the same folder structure. A file that refuses to open because of a forgotten password needs a separate step first, recover the PST password, then point the extractor at the unlocked archive.

Yes. Select a whole folder or a filtered set of messages and process them together, turning a full mailbox into one tidy folder of files without manual clicking.

Yes, because it does not rely on Outlook. The built-in command depends on your Outlook version and is often disabled or missing, especially in the new Windows 11 Outlook that pushes you toward OneDrive. This tool reads the saved .pst or .ost with its own engine, so a greyed-out button in Outlook never blocks you.

Yes. Every attachment is written as its own file in the output folder, with no zip archive to open first. You control the naming and whether the mailbox folder structure is recreated.

No. The engine opens a saved .pst or .ost on its own, so the tool runs on a machine that never had Outlook. You only need the archive file.

No. Everything happens on your computer and nothing is sent to a server. For a legal or finance mailbox, that privacy is the reason to choose a desktop tool over an online attachment extractor.

Yes. A .pst and an orphaned .ost open the same way, including the offline-cache .ost left behind after a mailbox has been removed.

It holds inline images back, filters out tiny footer files, and drops duplicates by content. Inline images stay off by default, files under your size threshold are skipped, and identical attachments are saved once.
