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.

    Nothing about your messages

    The report contains no messages, subjects, folder names, paths, or e-mail addresses; the only identifier is the first 8 characters of the Mac ID.

What you can do on the page

  • Generate creates the report (it can take a few seconds). Generate again rebuilds it. It holds the Klasor and macOS versions, the state of Outlook and the permission, the license, the schedule, recent runs and exports, and the latest log events, all in plain text, so you can read it before sending.
  • Copy puts the report on the clipboard so you can paste it into a message.
  • Support opens a new message in Outlook to support@klasor.app, with the report attached. You review it and click Send; nothing goes out on its own. If Outlook can’t create the message, the app copies the report and tells you where to paste it.
  • Debug mode keeps a more detailed log (numbers and codes, never subjects, folders, paths or addresses) and turns itself off after 24 hours. Use it only when support asks you to.
  • Export logs writes the log file on your Desktop, to attach to a message.

When to use it

  • Status shows “Needs attention” and you don’t understand why.
  • A labeling run or an export stopped.
  • You can’t activate your license.

Send the report to support@klasor.app (the address is also on the Contact page). The error code shown in the app (like KL-304) speeds up the answer. We usually reply within 1 to 3 business days; a report of missing messages is answered first.

Something seems to be missing after freeing space

  • Do not empty Deleted Items and do not press Free the space now until you have checked.
  • Open Free space → Deleted by Klasor, search for the message and use View. Every message Klasor moved is listed there, with its verified copy in your export.
  • To bring it back, tick it and press Restore to Outlook. If it is no longer in Deleted Items you can still restore it from the export.
  • Still not found? Write to support@klasor.app with the Diagnostics report and the name of the export folder. Do not send message content.
