IT & System Administration
MSG Tools for IT Teams & Sysadmins
For helpdesk technicians and system administrators who triage exported mailbox files, check message details, and recover attachments — lightweight, with no Outlook deployment.
Common scenarios
How teams use OpenMSG
Typical workflows for it & system administration teams. Every scenario runs locally on Windows — no Outlook required.
Helpdesk ticket triage from exported emails
When users forward problem emails as MSG files, support techs need to open them on any workstation. OpenMSG deploys as an MSIX package through Intune or SCCM, or installs from the Microsoft Store — with no configuration required.
Mailbox migration and recovery
During Exchange migrations or PST-to-MSG conversions, admins can end up with thousands of individual MSG files. OpenMSG lets you spot-check messages and confirm attachments open correctly after the migration.
Message details at a glance
When a ticket includes an exported email, OpenMSG shows the sender, recipients, subject, and sent date without an Outlook install — so admins can confirm what the message is and open or save the attachments.
