Which Exchange Online solution is best suited to your business?
Exchange Online Plan 1
Exchange Online Plan 1 offers everything businesses need for professional email communication. With business email, shared calendars and contacts, and secure access from anywhere, you can lay the foundations for modern working – without the need for your own email servers.
Exchange Online Plan 2
Do you need additional features for compliance, archiving and data protection? Or more storage capacity? Exchange Online Plan 2 extends the functionality of Plan 1 to include advanced security features and unlimited archiving. This makes the solution particularly suitable for organisations with more stringent regulatory requirements.
Microsoft 365 Business Basic and above
If, in addition to a cloud-based email solution, you’d also like to modernise collaboration within your organisation, Microsoft 365 plans such as Business Basic offer additional services such as Microsoft Teams, OneDrive and SharePoint. Depending on your requirements, further editions with enhanced features for productivity, security and device management are also available.
