IntelliJ License Collision with colleagues

Hi,

I have some strange license collison problems with two of my colleagues: In irregular intervals, IntelliJ reports at my computer or at my colleagues computer a license collision - although all of us have separate IntelliJ licenses registered to different Jetbrains accounts. When this happens, my colleages need to open the license settings in IntelliJ; in the settings dialog, my mail-address is present and they need to re-enter their own credentials. But after a while IntelliJ seems to change the license-settings back to my mail address causing a license collision.

This happens only with two colleagues in my team although there are plenty of other IntelliJ users in my company. This happens even when we are at different company locations in different cities (but we are on the same company network).

We are unsure, but eventually I gave them my IntelliJ settings as a JAR file. May this be the cause of the problem?

Is there a way to remove all license information from IntelliJ so that IntelliJ won't switch back automatically to my account? Grepping for my mail-address / username in the IntelliJ settings folder didn't gave us any results.

Thanks in advance
