Mailbox RescueExtract all attachments from a PST file
To extract every attachment from a PST or OST file, open it in Mailbox Rescue, click Export and tick Attachments as separate files. All attachments are saved in the same folder structure as the mailbox, named after their message number and original file name.
Steps
- Open the PST or OST file.
- Click Export. To save attachments only, untick everything except Attachments as separate files.
- Choose a folder. The report shows how many attachments were found and how many were written.
Single attachments
To save just one attachment, open the message and click Save next to it. This works in the free version too.
Windows 10 and 11, Intel/AMD and ARM. No account needed. Works offline.
Frequently asked questions
Do I need Outlook or a Microsoft 365 subscription?
No. Mailbox Rescue reads PST, OST and MSG files directly. Outlook does not need to be installed, and no Microsoft account or subscription is needed.
Is my mailbox uploaded anywhere?
No. Everything happens on your PC. The only thing the app ever sends over the internet is your licence key when you unlock the full version.
What does the free version do?
It opens, searches and shows every message, and saves single attachments, without limits. Bulk export stops after 25 messages so you can check the result before you buy.
Is it a subscription?
No. The full version is $9.99 once and works on up to 3 PCs.
