What is Archivia?
Archivia is a commercial email-archiving service operated by Suniworks in Switzerland. It gives an IT team an independent place to retain and search business email, including messages from former employees whose Microsoft 365 access is being retired. The archive is accessed through a browser on a computer, tablet or phone.
The service preserves archived messages, attachments and routing metadata. Search covers email text and extracted attachment content, including supported PDFs and OCR-processed images. Its two plans separate a one-time archive for inactive mailboxes from continuing synchronization and individual employee access for active mailboxes.
Suniworks describes a dedicated instance per customer, with separate application, database, storage and network resources. The provider operates the infrastructure and S3-compatible archive storage in Switzerland. These are the provider's published service characteristics, rather than results of an independent infrastructure inspection.
Archivia is an archive, not a complete messaging-system backup or a mailbox-restoration service. The service terms make that boundary explicit. A successful import must be checked before changing the source account or its license. Microsoft 365 retention and shared-mailbox options still need to be considered alongside an independent archive.
The latest version listed on the public release page is v1.0.3, dated September 3, 2026. This profile reviews the website and published terms on October 15, 2026.

Key capabilities
- Inactive-mailbox archiving The Archive seule plan is intended for former employees' mailboxes. It provides a one-time import, preservation, search and export without continuous synchronization or individual employee access. Verify the imported date range, message count and attachments before retiring the original mailbox.
- Continuing mailbox synchronization Protection complète covers active mailboxes, with synchronization advertised every 15 minutes and employee access to their own archive. That interval describes the scheduled workflow; it is not a contractual recovery-point guarantee or proof that every upstream message has already been captured.
- Search across email and attachments Find archived messages through keywords, sender, recipient and filters. The vendor advertises full-text indexing of messages, PDFs and OCR-processed images. Test representative languages and attachment types; encrypted, damaged or unsupported files may require separate handling.
- Retention enforced at storage The provider describes S3 Object Lock in Compliance mode for sealed messages. The terms set a one-year minimum retention floor unless a longer period is contracted. Retention begins when a message is archived, and already sealed messages cannot be released early by reducing a setting.
- Legal holds and an audit journal An administrator can hold mailboxes or saved-search results and inspect a hash-linked audit journal. Saved searches have a 100,000-result cap; newly matching messages join their hold after indexing, with a documented delay of up to 15 minutes. Journal verification does not detect end truncation, and logout is not recorded.
- Open-format export Export selected messages and archives in EML, mbox and CSV formats with a SHA-256 manifest. Active-mailbox users also get direct original-message downloads. A checksum verifies bytes against a reference; completeness and usability still need a separate check.
- Swiss-hosted customer environments The published privacy policy describes separate customer environments, provider-operated storage, local search and text extraction, and authentication through the provider's identity infrastructure. Stripe handles subscription payments. Mail content is not advertised as being sent to an AI-model provider.
- Managed commercial operation Suniworks runs the hosted service and publishes release notes, maintenance and support terms. The offer includes a 14-day trial that continues into paid billing unless cancelled. Messages imported during the trial are still subject to sealing, so a demonstration is the simpler way to explore the interface first.
Where Archivia fits
Preserving a departing employee's correspondence
A departing employee may leave contract discussions, delivery details and attachments that colleagues still need. Archive the approved mailbox scope, verify representative messages and complete the access handover before changing its source account. Keep responsibility for access and retention with a named administrator.
Searching an older business record
An account manager can need an attachment from a completed project without knowing which former employee received it. A central archive can provide a search surface separate from the old Outlook session. Use sender, recipient, dates and distinctive attachment content to test whether the archive answers that actual retrieval task.
Maintaining an archive for active teams
The active-mailbox plan adds continuing capture and employee access. Test permissions with two distinct test users, a newly arrived message and an interrupted source connection. Make the owner of connector failures explicit; a responsive archive interface does not prove that ingestion is current.
Holding a defined set of records
An administrator can apply a legal hold to an entire mailbox or messages returned by a saved search. Document the selection, business authority, scope and release process. The product supplies technical controls; choosing the correct records and duration is an organizational decision rather than an automatic certification.
Preparing an exit or migration
Export representative messages early, open their EML files in another mail tool and verify the manifest. For a full archive, the terms describe an administrator-initiated export and provider assistance on request. Agree who will obtain, verify and store that export before the service account closes.
