Does the Mac MSG converter need Outlook installed?
No. The software parses the MSG structure itself. Outlook can be absent from the machine entirely, which is the position most Mac owners are in when a colleague sends them a folder of these files.
What are the ten saving options of the MSG converter?
PST, PDF, MBOX, HTML, EML, ICS, EMLX, VCF, CSV and TXT. All ten appear together on the export panel and any one of them can be selected for a batch.
Can contacts and calendar items be pulled out separately?
Yes. An MSG file holds whichever Outlook item was saved, not only mail. VCF is offered for contact items and ICS for calendar items, so an address book saved out of Outlook reaches the Contacts app on macOS in a format it accepts.
Is there an upper limit on MSG converter batch size?
Neither the count nor the individual size is limited. Pointing Add Folder at a directory sweeps up every MSG file it holds, so a set numbering in the hundreds costs the same two clicks as a set of three.
What are the trial limits of the MSG converter software?
Ten items per selected folder. Counting happens per folder, not per batch, which means a set split across five directories yields fifty items to inspect rather than ten.
The application will not start and mentions Java. What now?
Java JDK and JRE 8 is listed as a prerequisite for this build. Where neither is installed the application cannot start the runtime and stops. Installing both clears it.
Does the MSG converter for Mac keep the folder arrangement?
Yes. The export panel carries Maintain Folder Hierarchy already ticked, which reproduces the source arrangement wherever the output goes. Clear the box and everything is written to one level.
Is there a way to exclude some messages from a batch?
Yes. Advance Settings carries a date filter alongside the category type and the PST split size, so a long set can be narrowed before the export begins.
Does the MSG converter tool change the source files?
No. Reading is the only operation performed on them. Results go wherever the Change button points, while the source files come through with their bytes and their timestamps untouched.
Will attachments survive the conversion?
Yes. Documents and images attached to a message are carried into the output rather than being dropped. The formatting around them is preserved.
Can the MSG converter upload emails straight to Office 365 or Gmail?
No. Conversion ends with a file on disk. Reaching a live mailbox is a separate step you take afterwards, usually by importing the PST output on the Microsoft side or the MBOX output into Gmail or Apple Mail.
Is there a Windows version?
This page covers the macOS build. A separate Windows edition exists as its own product and carries a longer list of export types, since two of them depend on Windows software.
