Conversion scope
Outlook, Thunderbird and Apple Mail do not understand CommuniGate storage so copying folders by hand gets nowhere. CommuniGate software opens the stored data on Windows and rebuilds every message as a standard file, with your source mail left as it was.

4Four mailbox formats sit inside CommuniGate Pro
CommuniGate Pro guide to mailbox formats says every mailbox uses a format set by its name extension. They are .mbox text files, .mdir folders with one file per message, .mslc sliced folders and .mb4 folders with partly binary data and Outlook opens none of them. CommuniGate converter opens the stored mail and saves it as standard files.

Core features
Five screens of Corbett software, in conversion order.
Source files
Select Open, then Email Server and choose CommuniGate from the list. CommuniGate converter looks for the configured profile on your PC and lists its mail on its own.
No profile found? Select Email Data Files and add your mailbox files and folders by hand. Your source mail stays as it was.
Batch loading
Select Choose Files for a few mailbox files. Select Choose Folders to load an entire directory in one step.
Loaded mail appears in one tree with a checkbox beside every folder so CommuniGate converter handles many mailboxes in a single session. No file size limit applies.
Message preview
Click any message and a reading pane opens beside five analysis views. Wrong folders or odd dates show up before anything is saved.
Content shows the email body. Message header lists From, To, Subject and Date. Properties reports message data, while hex and raw message views show the stored mail.
Output formats
Email files export to PST, EML or MBOX. Document files export to PDF, HTML or CSV. Export menu lists Gmail, Office 365, IMAP and Thunderbird for sending mail into an account.
Search by keyword first, then save only matched items. Quick search highlights hits in yellow and Advance search checks every field or only name, subject, To, Cc and content.
Export options
Switch on open folder after export, leave out greyed out folders, create empty folders and include email headers. For PST output, create an individual PST file for every folder so small files stay healthy.
Select Browse to choose a destination, then Save. Live progress shows every folder as it converts. Need Outlook steps? Open Import CommuniGate emails to Outlook.

I have been looking for a way to convert my CommuniGate data files for the last three days. I found this CommuniGate Converter Tool on Google and tried its demo edition. Yes, it works well for me, and I have exported all my import files without any difficulty.
I liked this solution because it helps me while converting data files. Being from a non-technical industry, I can perform this conversion without the help of technical assistance. The best part of the CommuniGate Server Converter is its GUI, which makes tasks more manageable.
I am an IT administrator, and one of my colleagues suggested using this CommuniGate Server Converter. I was curious how easily this software would conclude all the data files. Also, the software has various export options that make this software a prime choice for every user at a compelling price.
Before conversion
Three short checks keep your CommuniGate conversion clean.
Let the software find the profile
CommuniGate converter looks for the configured profile on your PC. When none shows up, add the mailbox files and folders by hand.
Convert from a copy
Copy the CommuniGate folders to a spare drive first. Conversion then never touches live mail and a failed job costs nothing.
Leave free disk space
PST and PDF output takes more room than the source. Keep free space on the target drive equal to your mailbox size and more for PDF.
Moving converted mail to Gmail is covered in Migrate CommuniGate to Gmail.
Best practice
Your conversion only helps if your mail arrives in full. Four habits keep your data safe through it.
Backup first
Copy your original mailbox files before you start. Keep 3 copies on 2 types of media with 1 copy off site.
Start with one mailbox
Convert one small mailbox with CommuniGate utility and open a few emails in your new format. Catch a wrong setting before a large job.
Check the count
Compare the message count in the folder tree with the mail in your output before you close the job.
Keep originals until checked
Store your source mail until counts match. Delete it only after you open converted mail.
