The auditor wants five years of a former employee’s mail. The mailbox was deleted last year — Aquila I Email Archival journals inbound, outbound and internal mail from Microsoft 365 and Google Workspace into write-once storage, with retention rules, indexed search and an Auditor role — quote-only, with the storage region unpublished.

This page covers Aquila I Email Archival — the archive for Microsoft 365 and Google Workspace mail. The rest:
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
It keeps a tamper-proof copy of every message for a set retention period, searchable for audits and disputes.
What consolidation actually replaces, dimension by dimension.
| Dimension | Mailboxes and ad hoc exports | Aquila I Email Archival |
|---|---|---|
| Mail of someone who left | Gone when the licence is reclaimed | Still in the archive under its retention rule |
| A request from legal | Admins export mailboxes one by one | One indexed search, then a secure export |
| Proof nothing was altered | Mailboxes users can edit and delete from | Write-once storage with a full audit log |
| Two mail suites in one group | Separate tools for Microsoft and Google | One archive journaling both platforms |
| Who can search the record | Only the mail administrator | An Auditor role, signed in through SSO |
| What it is NOT | — | A backup, a chat archive, or a published price |
The cheapest test is one domain: journal it for a month, run a real legal search, and export the result before you sign.
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Microsoft 365 or Google Workspace sends a journal copy of every inbound, outbound and internal message by SMTP, with headers, MIME structure, metadata and attachments intact.
Aquila I describes write-once, append-only storage, encrypted at rest and in transit, so a message cannot be edited or deleted early. Where that storage sits is not published.
Admins set retention by regulatory or business need and the platform enforces it, while an index of text and metadata filters by sender, recipient, attachment, keyword and date.
Admin, Auditor and End User roles sign in through Azure AD or Google over SAML or OIDC, with MFA for privileged accounts; every search, export and admin change is logged.
SMTP journaling from Microsoft 365 and Google Workspace into write-once storage — retained by policy, indexed, opened through SSO roles.
Aquila I Email Archival keeps a write-once, searchable copy of every message your Microsoft 365 or Google tenants send and receive.
SMTP journaling captures inbound, outbound and internal mail, so the record never depends on users keeping their own folders.
Both big cloud mail suites are named, which matters to groups whose units run different ones. On-premises Exchange is not named.
Headers, MIME structure, metadata and attachments are kept as transmitted, which Aquila I says keeps each copy fit for evidence.
Append-only storage is meant to stop tampering, alteration or accidental deletion for the whole retention period, by Aquila I’s account.
Retention periods are set to match regulatory or business needs and applied automatically, with every enforcement action auditable.
Aquila I lists migration from legacy retention systems; ask which source formats it reads, who does the work and what it costs.
Search filters by sender, recipient, attachment, keyword and date range, aimed at legal requests and at internal investigations.
Results leave through secure export workflows and structured audit reports; the export file format is not published, so ask for it.
Admin, Auditor and End User roles, SSO via Azure AD or Google, MFA for privileged users, and a log of every search and export.
Here’s what genuinely sets it apart — and exactly where it stops.
Aquila I names Microsoft 365 and Google Workspace for its journaling capture, inbound, outbound and internal. That suits Indian groups where a plant or a subsidiary runs Google while head office runs Microsoft. Archives built around Exchange, such as TitanHQ ArcTitan and Barracuda’s, do not claim Google mail.
Aquila I describes WORM, append-only storage and retention enforcement that is deterministic and logged, which is what an auditor asks to see when email is a business record. Microsoft’s archive mailbox is a per-user store instead, and Microsoft does not permit journaling into it.
A separate Auditor role, SSO through Azure AD or Google over SAML or OIDC, MFA for privileged accounts, and a log of every search, export and admin change. Compliance or legal can search the record without a mail administrator running each query, and the log shows who looked at what.
Aquila I does not publish where the archive is hosted, the first question for an Indian archive under DPDP and RBI or SEBI record-keeping. No price, meter, bulk export format or named customer is published; legal hold is not named as a feature, and Teams or chat capture is not claimed.
List Microsoft 365 and Google tenants, mailbox counts, and the retention each regulator or contract demands of you.
Ask Aquila I where the archive is stored, how it is metered and how a bulk export works; log it in your DPDP register.
Point journaling from one tenant or domain at the archive and check that inbound, outbound and internal mail all arrive.
Have legal run a real search by sender and date, export it, and confirm the Auditor role sees only what it should.
Plan the legacy-archive import, set final retention rules, and sign only once the exit format is in the contract.
Modelled on Gartner Peer Insights structure. *Counts and breakdowns are illustrative pending verified review collection.
“Our Google Workspace plants and the Microsoft 365 head office now journal into one archive. Legal searched both at once.”
“The Auditor role lets our compliance team run searches themselves, so the mail admin is no longer the bottleneck.”
“Journaling from Microsoft 365 took a day to set up. Bringing ten years of the old archive across took weeks, with their help.”
“A search by sender, attachment and date found an ex-employee’s thread for a dispute in minutes, and the export held up.”
“We needed the storage region in writing for our DPDP register. It took two rounds of follow-up before the answer came.”
“The quote had no per-mailbox rate to set against the archive already in our E3 plan. Ask for the meter early.”
Analyst firms bury this view behind paywalls, and review-site grids score satisfaction, not fit for your estate. So here’s TechBag’s synthesis of the email archiving market — tap any vendor to see why it sits where it does.
Execution strength vs product vision — the classic market map, minus the paywall.
Quote-only; no meter, region or named customers published.
The grid nobody publishes — how strictly an archive locks down and audits the record vs how much it captures: mail suites, Teams, chat and voice.
M365 and Google by journaling; WORM and an Auditor role; no named hold.

Drag the sliders (mailboxes in scope; staff-hour cost). Estimates model the IT and legal time spent finding, exporting and checking old mail for audits, disputes and investigations, at an assumed 1.5 hours per mailbox a year, with 70% of it removed by one indexed, policy-retained archive. Both figures are assumptions. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models your actual environment and modules.
Quote only. Aquila I publishes no price for Email Archival, no rupee price and no meter, so it is not clear whether you pay per mailbox, per GB stored or per year of retention. Its copy lists migration from legacy retention systems but does not price it. Set any quote beside Microsoft’s Exchange Online Archiving at $3.00 a user a month, or the archive already inside E3, E5 or Business Premium. TechBag gets the quote itemised in INR with GST.

Where is the archive physically stored, in which cloud and region, and will Aquila I commit to India in the contract?
Is the price per mailbox, per GB stored or per year of retention, and how does cost grow as years of mail pile up?
In what format can the whole archive be exported at contract end, how long does that take, and is there a charge?
Can a mailbox or a case be held so retention rules cannot delete it? Legal hold is not named in Aquila I’s copy.
Are both Microsoft 365 and Google Workspace in scope, and is on-premises Exchange or another mail server supported?
How is write-once storage enforced, and who, if anyone, can purge a record before its retention period ends?
Which legacy archives and file formats can be imported, who does the migration work, and is it priced separately?
Does your Microsoft 365 plan already include archiving? Check E3, E5 or Business Premium before buying a second one.
Size your mailboxes and retention rules first, or let a TechBag advisor get the storage region, meter and exit format from Aquila I in writing before a one-domain pilot.
