Can I use the same email address to setup Qbox account on two computers? #

You need a unique email address for each computer. To access files on a second computer, share the Sync folders with another email address, and setup Qbox with that email.

Qbox flashes a warning message saying Qbox folder cannot be accessed.

Qbox needs to access the Qbox folder periodically, and will flash a warning if it cannot be accessed. If your Qbox folder is on a network drive, it is possible that your local area network is not reliable, causing Qbox to lose access intermittently. You can try moving the Qbox location to a local drive or a different network drive to resolve the issue.

One of the users locked the file. Can I release the lock manually? #

File lock can be released manually by the account owner, Team member with admin permission or by the user who locked the file. Please note that when the lock is released manually, the file will not sync and changes made by the user who locked the file may get overwritten by a sync from another user.
