Outlook Attachment Extractor software pulls every file attachment out of Outlook .PST and .OST archives at once. It filters by type, drops duplicate copies, and saves the files to a folder, without Outlook installed.
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 an attachment count next to every email.
Check the folders you want, or switch the source to the messages you select. A text filter on the subject line or sender narrows a large mailbox down to what you actually need.
Filter by file type, keeping only PDF, DOC, XLS, images, or ZIP. Skip tiny signature logos below the size you set and drop duplicate files by content. You also decide how same-name files are handled.
Choose an output folder and click Start. Files are saved in the PST folder structure or flat, named as the original or Date_Subject_Name, with an optional CSV report of everything written.
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 tool at a 10 GB archive and it clears the whole mailbox in one run, with no Outlook and no add-in to set up.
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.
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.
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.
Saving attachments by hand means opening each email and clicking Save As, one file at a time, and Outlook's own 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 tool reads the archive locally and works through a 50 GB file in a single pass, so a full mailbox becomes a clean folder of files in minutes, with the signature logos and duplicate copies left out.
The left pane shows the .PST or .OST folder structure. The message list adds an Attachments column, so you can see which emails actually carry files before you extract anything.
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 your own extensions beyond the common office and image formats.
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 then lists every file that was extracted and where it went.
Pull the 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 doubles as a log of what was collected.
Harvest attachments from a departed employee's .pst, or from an orphaned .ost left behind when a mailbox is gone. It needs no Exchange connection and no Outlook profile.
Collect years of invoices and contracts out of a shared mailbox into dated folders, de-duplicated and ready to file, instead of saving them one email at a time.
