Moving email archives from Apple Mail, Thunderbird, or the old Windows Live Mail often brings you face-to-face with mismatches in format. .eml and .emlx files work fine in anything but Outlook, which prefers .msg files for each message. Manually importing thousands of loose EML files into Outlook can often freeze Outlook, lose attachments, or break formatting.
Softaken EML to MSG Converter was used for real-time batch testing of the working migration tool. We took an archive of over 1,000 EML and EMLX files and converted them to .msg for Outlook
The migration question
To simulate a corporate email migration, a test environment was built with 1,250 .eml and .emlx files, over 2.5GB of data.
Main Challenges:
High Number of Files: More than a thousand individual message files from legacy systems.
Mixed Formats: Combination of standard EML and native Mac EMLX files.
Rich Attachments With PDF Files, Inline Images, and Rich HTML Signatures
Target Outlook: Microsoft Outlook supporting cleanmsg files.
If you drag and drop huge collections of files directly into Outlook, it tends to crash or lose media attachments. We were looking for an automatic conversion utility.
