I'm trying to run Thunderbird portable in Sandboxie but it doesn't work. I'm getting an access denied error - any ideas if it's possible?

I just downloaded Thunderbird v3.1.2 portable from and it seems to be working fine. Where are you getting the error? Did you run it in the Default Sandbox or Outside the Sandbox? – Isxek Sep 7 '10 at 11:24

  • You are probably not able to send/receive mail because the sandboxie might be boxing your thunder-bird's network access

  • Another reason could be because Mozilla people might have blocked this portable version

  • Some people are able to solve the problem by choosing "Auto-detect proxy" instead of having a "Direct Connection".

  • You Will be able to run Thunder Bird in Oracle Virtual Machine which also functions similar to a sandboxie
