As you remove the user the user will not be able to use the active subscription and his products would run in trial mode for 30 Days if and only if the user has not used the trial mode in past else it would not allow the user to use the program and ask to activate/license the adobe program(s).
how can adobe deactive my user machine? cause after first activation my user will be offline, not connecting internet.
thanks for your response
Un assignging the seats takes off the Adobe ID from the server, as you had correctly indicated that offline work can be done for some days, but there is no specific time frame for an unassigned seat to be able to work on CC.
Also as per End user license agreement, any unassigned seat should not be using CC with that Adobe ID.
