Tresorit Not Working? Common Errors & Fixes

Tresorit usually stops syncing because a device is offline, signed into a different account, sync is off for that tresor, or the file is a type Tresorit can't sync (shortcuts, symlinks, invalid names). Restart the app, check each of these, and rename or replace problem files.

Tresorit has no block-level sync, so every edit re-uploads the entire encrypted file; a small change to a 1 GB file can take over a minute and a half. Keep big, frequently edited files out of synced tresors, split large archives, and update the app.

On macOS 11.3 and later, Tresorit Drive appears under Locations in the Finder sidebar, not Favorites. If it isn't there, enable Locations in Finder settings, restart Tresorit and update to the latest macOS client.

Tresorit can't recover passwords because it never stores them. If you're still logged in on a device, change it there via Change password > Forgot password with an emailed code; otherwise only an account reset is possible, and it deletes all files.

When two people or devices change the same file before syncing, Tresorit keeps both versions and names the second one with "user@email.com's conflict". Compare the two, keep the right one and delete the conflict copy.

Tresorit camera upload can stop silently, especially after OS updates. Update the app, exempt it from battery optimization on Android, re-grant photo access, and if it still doesn't resume, log out and back in; missed photos may need a manual upload.

Each Tresorit plan has a maximum file size: 500 MB on Basic, 2 GB on Personal Lite, 10 GB on Essential, Pro and Professional, 15 GB on Business and 20 GB on Business Pro. Split or compress the file, or upgrade.

When your data exceeds your plan, usually after downgrading to the 3 GB Basic plan, Tresorit lets you view files but blocks uploading, sharing and syncing, and may remove data over the limit after notice. Delete files, empty deleted items, or upgrade.

Cancel Tresorit in your subscription settings at web.tresorit.com to downgrade to Basic at the end of the billing cycle (team plans: only the Subscription Owner can). Refunds apply only to first-time direct purchases with no trial: within 7 days, or 14 days in the EU.
