Share files outside the company, from inside Microsoft 365.
Every file type, from a contract draft to a 3D design file, goes to partners who sign in with their own company login, with no guest account to create.











The tools for sharing outside the company pile up over the years
Most enterprises never chose one way to reach the outside world. They accumulated several. A file-sharing service bought for one project, a secure email gateway added after an audit, a file transfer system that someone still maintains. Each solved a problem on its own. None were built to work together, and the bill for all of them climbs every year.
That accumulation has a name: Collaboration Debt.

One secure surface for everything shared outside the company
eSHARE gives people a common means to share outside the company, and sits inside Microsoft 365 rather than beside it. Someone shares from Outlook, Teams, or SharePoint, where they already work. The partner opens a portal carrying the organization's own brand and signs in with their own company login. Nobody creates a guest account, nobody raises a ticket, and no copy is left forgotten outside the tenant.
Share any file; edit Office and PDF files or annotate a 3D CAD (computer-aided design) model in the browser, without downloading a copy.
Send a document out, have the other side fill it in and sign it, and keep a verifiable record of who signed what.
Secure a sensitive email and its attachments, sent directly from Outlook.
Stand up a secure data room for a high-stakes exchange, where many documents and outside parties work under one set of rules.
