Troubleshooting and Support

Labs projects can change the DNA of Postbox in ways that are incompatible with its default behavior. If Postbox is not operating the way you expect, then temporarily disable all labs projects to see if the problem clears up for you.

Postbox, Inc. does not support the Postbox application after 3rd-party labs projects have been installed, nor does not support the functionality of 3rd-party labs projects themselves, as it is up to each developer to support the functionality of the code they author. If a project is not working correctly, please contact the developer directly.
