Convert OST to PDF with Attachments

It's not always convenient (or even possible) to connect to the internet. For this reason, Microsoft Outlook lets you save a local copy of your emails in the OST format. This allows you to access and work with your email data while offline, and later syncs to the server when you are back online. What happens though, when you need to share OST files with someone who doesn't use Outlook? Fortunately, with the help of our OST to PDF converter that is no longer an issue!

The Total Outlook Converter Pro was designed to assist you in all of your Outlook-related conversion needs. Whether you're looking to convert OST to PDF, or a variety of other more universally accessible formats, we've got you covered. Did you know that our Outlook Converter Pro even lets you restore OST to a new PDF file? That's right - now you can recover data from corrupted or damaged OST files too. Featuring a user-friendly interface backed by more than a decade of feedback and development, the Outlook Converter Pro is loaded with options:

• Add pagination.
• Include bates numbers.
• Rename output files.
• Combine several emails into one multipage PDF.
• Create searchable or non-searchable PDF/A.
• Include security settings.

Here at CoolUtils the idea is to create programs that help you to easily accomplish things that might otherwise seem impossible. We listen closely to our user feedback and we're continuously upgrading our converters with the functionality that you need.

For example, unlike other programs the Outlook Converter Pro lets you convert your email attachments too! When you go to convert your OST files to PDF, you'll be given the option to convert your attachments to PDF or leave them as OST.

Don't take our word for it - try it before you buy it! We offer a free 30-day trial version that will give you a better look at the GUI and you can experiment with the conversion process. If you like what you see and decide to get the licensed version, for just $99.90 you'll receive a lifetime license. All upgrades are free during the first year and our support staff is ready to help with any questions you might have.

Total Outlook Converter Customer Reviews 2026

"For a discovery production we needed every offline OST message converted to PDF with its attachments embedded in the same file, not scattered separately. Total Outlook Converter Pro handled a batch of several thousand emails overnight and opposing counsel received a clean, self-contained PDF set. The command line option let our IT team schedule the run outside business hours."

Charlotte Brennan Litigation Paralegal, Brennan & Cole

"We convert offboarded employees' OST mailboxes to PDF as part of our retention policy, and keeping attachments embedded rather than separate saves a real headache later. The batch process ran unattended overnight on our archive server without a single failed message. It has become the default step in our offboarding checklist."

Rafael Mendonca IT Operations Manager, manufacturing group

"An audit required PDF copies of an offline mailbox with attachments intact inside each document, and this converter did exactly that across a large batch. Working entirely offline was important since the emails contained client financial data. The initial setup of the attachment embedding option needed a careful read of the help file."
