IONOS Hosted Microsoft Exchange review
A focused Exchange service with 50 GB mailboxes, Outlook access, and shared team tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IONOS Hosted Microsoft Exchange is a managed business email service for organizations that want Microsoft Exchange without operating their own Exchange servers. It combines hosted email with calendars, contacts, tasks, shared mailbox and folder permissions, and Outlook access. The service is aimed at businesses ranging from startups to larger enterprises, with support for web, Windows, macOS, iOS, and Android users. Its 50 GB mailbox makes it a practical fit for teams that need more than basic business email storage while staying within the Microsoft Outlook ecosystem.
The published plan is straightforward: Hosted Microsoft Exchange costs $10 per user per month with annual billing. That plan includes the 50 GB Exchange mailbox, Microsoft Outlook and Outlook on the web, a 100 GB shared team folder, real-time synchronization across devices, premium virus protection, spam filtering, and 24/7 expert support. Calendar, contact, and task synchronization extend the service beyond email, while the shared mailbox and folder permissions support common team workflows. The email migration tool powered by audriga can help organizations move existing mail into the hosted environment.
Platform coverage is one of the service's clearest advantages, especially for teams that work across desktop, browser, and mobile devices. Optional email archiving is available through a separate compatible subscription, so organizations with retention requirements should account for that alongside the Exchange plan. IONOS also provides phone, chat, and email support. Choose this product when your organization specifically needs hosted Microsoft Exchange, Outlook compatibility, shared mail features, and a 50 GB mailbox. Consider another category of product if your priority is a broader collaboration suite rather than Exchange-centered email and scheduling.
