Advantage CloudVault365™

Advantage CloudVault365™ is a cloud-first, Microsoft 365-integrated email archiving platform — capturing, securing, and indexing every inbound and outbound email in real time, so organisations can retrieve any message instantly when required for compliance, audit, legal, or operational purposes.

It is designed specifically for organisations that need a reliable, searchable, and compliant email archive — replacing the fragmented mix of bloated mailboxes, local PST files, and manual search processes that most SMEs rely on when compliance requests arrive.

Microsoft 365 mailboxes store email, but storage and archiving are not the same thing. Standard Microsoft 365 retention policies and mailbox storage have several limitations for organisations with compliance obligations:

• Retention gaps — emails deleted by users before a retention policy captures them may not be recoverable, and default retention settings are not configured for regulatory compliance out of the box
• Search limitations — searching across multiple mailboxes simultaneously, applying complex filters, or producing an audit-ready evidence pack from native Microsoft 365 search is slow and labour-intensive
• PST file risk — many organisations have years of email in PST files on local drives or network shares, outside any retention or governance control, creating both a compliance gap and a data security risk
• No legal hold confidence — applying and managing legal holds across multiple mailboxes during litigation or investigation requires careful management that standard Microsoft 365 tools alone make error-prone

CloudVault365™ closes these gaps with dedicated archiving infrastructure designed from the ground up for compliance and retrievability.

CloudVault365™ is built to support organisations operating under a range of regulatory frameworks that require email retention, auditability, or the ability to produce email records on demand:

• GDPR — maintaining records of processing, demonstrating data subject access request compliance, and being able to produce or delete email records as required
• FCA regulations — financial services firms are required to retain records of client communications, including email, for defined periods (typically five to seven years depending on the regulation)
• ISO 27001 — information management and audit trail requirements that email archiving directly supports
• Sector-specific requirements — healthcare, legal, local government, and other regulated sectors all have specific record retention obligations that CloudVault365™ is configured to meet

Advantage configures retention policies within CloudVault365™ to match the specific regulatory requirements of each client's industry and jurisdiction.

A legal hold (also called a litigation hold) is an instruction to preserve specific electronic records — including emails — that may be relevant to actual or anticipated legal proceedings or regulatory investigations. Once a legal hold is applied, those records must not be altered or deleted, regardless of any routine retention or deletion policies that would otherwise apply.

CloudVault365™ enables legal holds to be applied to specific custodians, date ranges, or search-defined sets of emails — locking them from modification or deletion while the hold is in place. This provides the documented chain of custody that courts and regulators expect when email evidence is produced, and removes the manual process of notifying individual staff to preserve their own emails (which is unreliable and creates risk).

CloudVault365™'s search is built for compliance and legal retrieval — not general inbox search. It indexes the full content of every archived email, including attachments, alongside metadata (sender, recipient, date, subject, size, attachment names). Searches can be constructed using any combination of these fields and returned results can be filtered, sorted, and exported in formats suitable for audit, legal disclosure, or regulatory submission.

For compliance teams responding to a regulator request or legal team conducting disclosure, this means producing a complete, filtered set of relevant emails — with full traceability of what was searched, what was returned, and what was exported — in minutes rather than hours or days of manual mailbox trawling.

CloudVault365™ integrates natively with Microsoft 365 — capturing email directly from Exchange Online in real time without requiring any changes to how staff send and receive email. The archiving process is entirely transparent to end users: emails continue to arrive and be sent normally through Outlook or any other Microsoft 365 mail client, while CloudVault365™ captures a tamper-proof archive copy automatically.

For users who need to access archived emails — for example, to retrieve an old message that has been deleted from their mailbox — CloudVault365™ can be accessed directly from Outlook via an integrated add-in, or through its own search interface, without needing to contact IT or raise a support ticket.

CloudVault365™ supports configurable retention policies that can be set at organisation level, department level, or for specific users — defining how long different categories of email are retained before being eligible for deletion. Policies can reflect specific regulatory requirements (for example, retaining all client communications for seven years for FCA-regulated firms) or internal governance requirements.

Retention policies are enforced automatically — emails are not deleted before their retention period expires, regardless of whether users delete them from their own mailboxes. At the end of the retention period, emails can be automatically removed in accordance with a data minimisation policy, or flagged for review before deletion. This combination of guaranteed retention and controlled disposal is what gives organisations the compliance confidence that manual mailbox management cannot provide.

Yes — CloudVault365™ stores archived email on Microsoft's enterprise-grade cloud infrastructure, with encryption in transit and at rest. Access to the archive is controlled by role-based permissions — only authorised individuals (compliance officers, legal team members, IT administrators) can access archived email, with full audit logging of every search, access, and export action.

The tamper-proof nature of the archive is a critical compliance feature: once an email is captured, it cannot be altered or deleted (outside of legitimate retention policy disposal or legal hold release). This immutability is what makes CloudVault365™ appropriate for producing email as legal or regulatory evidence — it provides a verifiable chain of custody that a live mailbox or PST file cannot.

Implementing CloudVault365™ does not require starting from a blank slate. Advantage manages the ingestion of historical email into the archive as part of the deployment — including importing existing PST files, migrating email from legacy archiving systems, and capturing historical Exchange Online mailbox content up to a defined cutoff date.

This historical ingestion is important for organisations with existing compliance obligations: if a regulatory request covers a period before CloudVault365™ was deployed, the historical archive needs to be in place to respond. Advantage scopes the historical data migration as part of the initial implementation and manages the process to ensure continuity of the archive record.

Advantage implements CloudVault365™ using its Analyse, Activate, Aftercare methodology:

• Analyse — reviewing your current email environment, existing retention policies, regulatory obligations, and historical email estate (including any PST files or legacy archives). Designing the retention policy framework appropriate for your industry and compliance requirements.
• Activate — deploying and configuring CloudVault365™, connecting it to your Microsoft 365 environment, ingesting historical email and PST files, configuring retention policies and access controls, and confirming compliance with a test retrieval and audit trail review.
• Aftercare — ongoing management of the archive including retention policy reviews, storage monitoring, user access management, and support for compliance requests and legal holds as they arise.
