"A client was moving off Outlook entirely and needed every message exported as EML for import into Thunderbird. Total Outlook Converter integrated with the mail account, exported the checked folders in one batch, and every message kept its full structure without any header data getting lost."

5 Star Adrian Voss Email Migration Specialist, Voss IT Consulting

"We switched our front desk staff to a different mail client and needed the old Outlook history saved as EML so it could be imported cleanly. Total Outlook Converter ran through the command line, exporting each message as a separate EML file with no manual copying required."

5 Star Monique Fontaine Office Administrator, Fontaine Dental Group

"Converting Outlook to EML was necessary before decommissioning an old mail server. Total Outlook Converter batch-exported thousands of messages without breaking the email structure, which I was worried about beforehand. A progress bar showing estimated time remaining would be a nice addition."
