Client email archives arrive as .msg exports
When a partner or client sends archived Outlook emails as .msg files, your team needs to open them immediately — even on machines without Outlook. OpenMSG lets anyone in the office view the full email and download attachments in one click.
Onboarding new staff without Outlook licences
Not every employee needs a Microsoft 365 subscription. Contractors, interns, and part-time staff can still review forwarded MSG files using OpenMSG — saving your organisation licence costs.
Auditing email trails for project hand-offs
When projects change hands, exported MSG files document the communication history. OpenMSG lets the new lead quickly review every message, extract key attachments, and get up to speed without delay.
