Helpdesk ticket triage from exported emails
When users forward problem emails as MSG files, support techs need to open them on any workstation. OpenMSG installs in seconds from the Microsoft Store and requires zero configuration — ideal for shared helpdesk machines.
Mailbox migration and recovery
During Exchange migrations or PST-to-MSG conversions, admins end up with thousands of individual MSG files. OpenMSG lets you quickly spot-check emails, verify content integrity, and confirm attachments survived the migration.
Header inspection and troubleshooting
Diagnosing mail-flow issues often requires inspecting email headers. OpenMSG displays the full message metadata so admins can trace routing paths, check SPF/DKIM results, and identify delivery problems without Outlook.
