Filing intelligence

Smart folder suggestions that actually learn

The first time you file an email from a sender, HyperFiler remembers where it went. The next time, the right folder shows up as a green-banner suggestion. One click and it's filed. No more rifling through 200 folders to find the right one.

Per-sender filing memory stored locally on your device
Domain-level fallback when an exact sender match isn't found (e.g. files sarah@company.com to the same place as john@company.com)
Search any folder by name, or browse the full tree visually; both modes built in
Folder cache refreshes daily to pick up new folders you've added

Attachments

Save attachments to OneDrive in the same click

When the email has attachments, HyperFiler shows them inline with Copy and Move buttons. Copy keeps the attachment in the email and saves a duplicate to OneDrive. Move saves the attachment to OneDrive, removes it from the email, and leaves a "moved to OneDrive" watermark in the email body with a link to the file. Mailbox stays small, the email stays useful, and the file is one click away.

Suggested OneDrive folders based on filing history, just like emails
Works with personal OneDrive and any SharePoint site you have access to
The watermark link in the email always points back to the OneDrive file, so the attachment is never really lost
Supports any file size your OneDrive plan allows

Email archiving

Save important emails to OneDrive folders

Tick the optional checkbox to save a searchable .eml copy of any email to OneDrive or SharePoint, alongside its attachments. Particularly useful for compliance, audit trails, or just keeping a record of contractually important conversations outside the mailbox.

Saves the full email as a standard .eml file that opens in Outlook with one click
Filename format: "2026-05-08 Sender Name — Subject.eml" (sortable by date)
Picks the same OneDrive folder as your attachments by default, so everything stays together
Per-email opt-in — you decide which emails are worth saving

Insight

See who's flooding your inbox

The Email Audit button exports your full inbox history to CSV: who's sent you the most emails, how many had attachments, when correspondence started and ended, and the top folders each sender ends up in. Open it in Excel, sort by volume, and decide what to delete, block, or auto-file.

One row per unique sender, sorted by total email count
Top five filing locations per sender, with counts — spot inconsistent filing
Date range showing first and last email from each sender
Attachment counts per sender — identify your heaviest correspondents
Slice it however you want in Excel: pivot tables, filters, charts

Cleanup

Block senders you're done with

Some senders aren't worth filing, they're worth blocking. The Block button moves the current email to Junk and adds the sender to your Outlook block list, so you never see them again. In the other direction, every sender you file is automatically routed to your Focused inbox in future, so important email stays visible.

Block button on the main pane: one click to send the current email to Junk and add the sender to Outlook's block list
Future emails from blocked senders go straight to Junk, no further action needed
Focused Inbox override: senders you file are automatically routed to your Focused inbox in future, so important email never gets buried under newsletters
Audit CSV shows everything you've filed and where, so any move is easy to trace

For enterprise users

Works on locked-down tenants

A "locked-down" Microsoft 365 tenant is one where IT has restricted what add-ins can do, usually for security reasons in regulated industries (legal, finance, healthcare, government). Most Office add-ins fail silently on these tenants because the tenant security policy blocks the add-in tokens they depend on. The user clicks the add-in button and nothing happens.

HyperFiler is built differently. A Cloudflare Worker authenticates with Microsoft Graph server-side, so the tenant policies that break other add-ins don't break HyperFiler. If you work somewhere with strict IT controls and other filing add-ins have stopped working, HyperFiler is worth trying.

Bypass-by-design: no reliance on Outlook's add-in token mechanism
Uses standard Microsoft Graph endpoints and OAuth scopes, nothing exotic
For very tight tenants, your IT admin can pre-approve via Microsoft 365 admin center
