Immutable by Design
Every message is locked and tamper‑proof, meeting compliance and eDiscovery requirements.
Immutable Email Archiving That Protects Every Message — Automatically
Simplify compliance and email management with a secure, cloud‑based archive that captures, encrypts, and preserves every email before it even reaches your inbox.
Stop wasting hours on inbox chaos and compliance headaches.
Manual archiving, lost messages, and outdated PST backups create gaps that put your data, compliance, and peace of mind at risk. Every missed or altered email could mean lost evidence, a failed audit, or a damaged reputation.
Microsolve’s Immutable Mailbox Archive runs quietly in the background — capturing every message across Microsoft 365, Google Workspace, and other email systems in real‑time.
Each message is encrypted, indexed, and stored in an immutable archive (hosted with AWS), ensuring it can never be modified or deleted.

Frequently Asked Questions
Choosing the right email archiving solution is about more than storage. It’s about compliance, security, and peace of mind.
We’ve gathered the most common questions about Microsolve’s Immutable Mailbox Archive to help you understand how it protects your business emails, supports data protection and compliance obligations, and keeps every message safe and accessible in the cloud.
What is Microsolve’s Immutable Mailbox Archive?
Microsolve’s Immutable Mailbox Archive is a secure, cloud-based system that captures, encrypts, and stores every email message before it reaches your inbox. All emails are stored in an immutable (unchangeable) archive on AWS, ensuring data integrity and easy retrieval at any time
How does the archive improve email management?
It removes pain points like slow searches, lost emails, and the need for manual backup PST files by indexing and de-duplicating all messages. This makes finding emails fast and simple, even years after receipt
What does 'immutable' mean for our archived emails?
‘Immutable’ means that once emails are archived, they cannot be modified or deleted. This guarantees authenticity, supports legal compliance, and protects organisations from accidental or malicious data loss.
Is the Microsolve archive secure and private?
Yes. All emails are encrypted during transmission and while stored in the archive, providing strong protection against unauthorised access or data breaches.
Will this system help with compliance and discovery requests?
Absolutely. The platform is designed for compliance, making it simple to locate, review, and export archived emails for audits, investigations, or legal requirements. This can reduce both cost and compliance risk.
Does the system work for all email platforms?
Microsolve’s archiving solution is platform-agnostic and can be applied across most major email systems used by businesses today. Talk to Microsolve to confirm compatibility with your existing email provider.
How is the archive managed and accessed by our team?
Authorised users can quickly access the archive through a secure web interface, supporting fast searches and reliable email recovery. Administration is straightforward, and no user training is needed beyond standard onboarding procedures.
Which Package is Best for Me?
For small to medium Organisations, license each user mailbox - everyone will be able to access their own archive. Designated users can be provided enhanced privileges for discovery and reporting.
For larger organisations, license just those users who will act as compliance officers and the exec team. Add storage to cover all of the non-licensed mailboxes.
Are there volume discounts?
Sure. We can provide custom solution pricing based on your organisation characteristics.
Our platform is highly scalable and with access to the AWS storage cloud, virtually limitless!
How long should business emails be retained for compliance in Australia?
Email retention requirements depend on your industry and relevant legislation.
Many Australian organisations retain business emails for at least seven years for audit, tax, and regulatory compliance purposes.
Microsolve’s immutable archive supports configurable retention periods to meet policy and legal obligations.
Where is archived email data stored and is it kept in Australia?
All archived emails are stored in the AWS Sydney and Melbourne regions, ensuring your organisation’s data remains within Australian jurisdiction.
This provides strong data sovereignty compliance and faster access for local users.
