Your mail, in order.
Set it up once. Klasor labels your messages in Outlook for Mac in the background, and exports verified .eml files whenever you need them, by folder or by label, with SHA-256 checksums. Labeling and exporting never delete, move or send anything.

Compatibility: Klasor works with classic (Legacy) Outlook for Mac. Since October 2026 Microsoft no longer lets it connect to Exchange Online (Microsoft 365 work accounts). The change applies only to Exchange Online mailboxes: IMAP and on-premises Exchange accounts can keep working (we have tested IMAP; on-premises Exchange not yet), and Microsoft supports it with on-premises Exchange until 9 October 2029.

What it does
01
Label
Every folder gets the project label, and you can change it with one tap.
02
Automate
Pick a schedule, from every 15 minutes to every Friday, and Klasor labels new messages in the folders you applied labels to, while Outlook is open. Switch any folder off, and every run is logged in History.
03
Export
Plain .eml files you can still open years from now, with a manifest and SHA-256 checksums. By folder or by label, to iCloud, OneDrive/SharePoint, a network share or an external drive.
04
Verify
Every export is checked before and after copying, and again whenever you ask. If an export goes missing or is incomplete, Status tells you at once, with no false alarms.
05
Free space
Optional: when you want a lighter mailbox, Klasor can move messages out of Outlook, only those whose exported copy is verified again just before the move, after you confirm. Search and read them in the archive, and restore any of them. BETA: tested with Gmail added as IMAP and with a private IMAP server; on other accounts the final delete-for-good step is off until you allow it.
One app, three levels of detail
Start simple. Open up more when you want it.
Level 2
Advanced
The same screens with more detail in place: rows that open, a preview of the latest messages, the log of recent runs and a Simulate button. When you free space, it also lets you change what is always kept in Outlook.
Level 3
Pro
A permanent side panel and a wider window, built for speed, with a ⌘K search.
All three levels are included in every plan.
Pricing
Simple pricing, no surprises.
