Guides
Installation, labelling, export, freeing space, accounts, license, and Outlook for Mac.
Getting started
Installation and first launch
From the installer file to your first scan: the installer, the permission for Outlook, and what to do if macOS asks you something.
Scanning your mailbox and choosing labels
Klasor reads Outlook, suggests a label for each folder, and applies it only when you confirm. A label is an Outlook category, named after the folder.
Automation: labeling new messages by itself
After you apply labels once, Klasor can label the new messages in those folders on a schedule, in the background, while Outlook is open.
Standard, Advanced and Pro: three levels of detail 2.0
The same app, three levels of detail. Standard is calm and simple; Advanced and Pro add detail in place, for people who want to see more. All three are included in every plan.
Which accounts work, and how to add them 3.0
What Klasor can do depends on how the account was added to classic Outlook. The table shows what works and what we tested; the steps show how to add a Gmail or other IMAP account.
Export and backup
Double-verified .eml export
A backup of your messages that you can open years from now, without Outlook: .eml files, with a SHA-256 checksum and verification after copying.
What the export screens and states mean
An export is only useful if it still exists and is complete. Klasor tells you plainly when it paused, when it finished with problems, and what it found when it re-verified.
How to recover messages from an export
You have .eml files and a manifest. Here’s how to check that they’re intact and how to bring them back.
Free up space in Outlook, safely 3.0
An optional step, off until you turn it on: Klasor moves messages out of Outlook only when their exported copy is verified, you confirm every run, and you can bring any message back.
License and support
License: trial, activation, moving to another Mac
A free trial of 7 days or 1,000 messages, with no bank card to add, then one key for each Mac. How to enter it, how to move it.
Diagnostics and support
When something isn’t working, a short report shows what’s going on. You copy it and send it to our support address, support@klasor.app.
Troubleshooting: the most common problems
The message in the app, the likely cause, and the fix, in brief.
Complete uninstall
How to remove Klasor from one place, without leaving scheduled tasks or configuration files behind.
Privacy: what happens to your data
Your messages stay on your Mac. The license server sees only what it needs to verify a license.
Outlook for Mac
From New Outlook to Legacy Outlook on Mac
Klasor works with Legacy Outlook. How to switch back to it, what happens to your accounts, and what the end of support means.
.olm export: a secondary backup, including by category
An .olm file keeps your messages and folder structure in Outlook’s format. How to make one in Legacy Outlook, whole or for a single category, and how to export several labels at once with Klasor.
Remove a label from messages, in Outlook
Turning a folder off in Klasor only stops new labeling. If you also want the label gone from messages that are already labeled, you do it in Outlook, in four steps.
