Company proxy support
To set up DFO / Tresorit Drive add "drive.tresorit.com" to the proxy exclude list and please also make sure to opt for direct connection. If you are using manual proxy configuration then Tresorit Drive will be added automatically to this exclude list.
📝 Note: drive.tresorit.com points to your local machine [127.0.0.1] where Tresorit runs, so no proxy required to make it work.
If you use your company's proxy then there is a chance that automatic configuration of the exclude might fail. You can check if this if the issue under LAN settings.
- Open up the Control Panel.
- Navigate to Internet Properties.
- Open the Connections tab.

If needed, consult your proxy server's documentation for further investigation.

Known compatibility issues
WebDrive
WebDrive seemingly intercepts and blocks the communication between your machine and Tresorit Drive / DFO. As of now, the only workaround known to us is uninstalling WebDrive.
Broken link in Outlook
When you attach a Tresorit Drive file to an Outlook email, choosing the Share link option will cause a bug in Outlook and recipients won't be able to open your link. If you want to attach Tresorit Drive files, always opt for the Attach as copy option.
