How It Works

Read Data From Any Source, Send It Anywhere

Whether your data sits in a folder of orphan files, an installed desktop client, a live IMAP account or an enterprise mail server, PCDOTS reads it directly and writes to the destination of your choice.

Source 01

Email Data Files

Have a folder of orphan PST, MBOX, OLM or DBX files? PCDOTS reads them directly without the source client installed and converts them to the format or service you need.

  • Bulk-process thousands of files in a single batch
  • Folder hierarchy and metadata fully preserved
  • Works without the original software installed

  • Auto-detects installed clients and profiles
  • Preserves rules, labels, signatures, attachments
  • 11 desktop clients supported natively

Why Choose PCDOTS

Two Decades of PC Software Engineering

Since 2005, PCDOTS has built the same trusted PC software product family for IT teams worldwide. Every release is regression-tested against thousands of real-world samples, so the data you depend on is never the casualty of a routine task.

  • 100% Safe and Secure

    Your mailbox data never leaves your machine unless you explicitly send it to a cloud destination. Every transfer uses TLS encryption.

  • Flexible Graphical Interface

    Generous typography, sensible defaults, no clutter. Designed so a stressed admin at 2 a.m. can still finish the job correctly.

  • Original Structure Preserved

    Folder hierarchy, read and unread state, attachments, embedded images and internet headers move across exactly as they were.

We migrated 12,000 mailboxes from a legacy MDaemon setup to Office 365 over one weekend. Nothing broke. Folder structure, rules and headers all came across exactly the way they were on the old server.

What Our Customers Say

Comments from administrators, lawyers and small business owners who used PCDOTS during real migrations and recoveries.

★★★★★
"PCDOTS Email Converter is one of the best tools I have used. It came in handy when I was moving multiple files from MDaemon Server in a simple, straightforward way. It saved me a great deal of time."

★★★★★
"My MailSpring account stopped working unexpectedly. After 3 to 4 frantic days of searching manually, I came up empty. Then I used PCDOTS and the issue was resolved instantly. Highly recommended."
KJ
Kylie Johnn
New Town, Sydney
★★★★★
"There are many email migration tools online, but few let you migrate emails along with all the email items. PCDOTS is ideal for migrating and recovering individual items without any data loss."
