GmailOutlook

GmailOutlook is a hypothetical interoperability concept or project aimed at enabling a unified email experience across Google's Gmail and Microsoft's Outlook ecosystems. In this sense, it describes either a formal product, a third-party integration, or a set of practices designed to bridge Gmail and Outlook accounts, calendars, and contacts to reduce fragmentation for users who maintain accounts in both platforms.

Technically, GmailOutlook would rely on established standards and APIs such as IMAP and SMTP for mail transport, CalDAV and CardDAV for calendars and contacts, and OAuth 2.0 for authorization. It might be augmented by platform-specific APIs like the Gmail API and Microsoft Graph to enable deeper integration. The goal would be to provide features such as a cross-account inbox, synchronized contacts and calendars, unified search, and the ability to act in one ecosystem from the other.

Use cases include business environments migrating between platforms, individuals who use both Gmail and Outlook, and IT teams seeking reduced training and improved data consistency. Potential limitations involve gaps in feature parity, dependency on account permissions, rate limits, and privacy or data-residency considerations depending on where data is processed and stored.

Status and context: there is no widely adopted official product named GmailOutlook. Interoperability between Gmail and Outlook is currently achieved through standard protocols and enterprise integration tools, while both Google and Microsoft provide APIs to connect third-party systems. Security, privacy, and policy differences can complicate cross-platform data sharing, influencing what is feasible in practice.
