We have users with mobile numbers attached who leave the organisation. The mobile is re-assigned to a new employee who may have a different role so we cannot replace them.
Even though we remove the mobile number from the old employee account we are not able to re-use this number for the new employees account as it is saying it still exists.
We don’t want to delete the old employee as their name is associated with previous records which need for auditing purposes. Why is it not allowing us to re-use the mobile when we have removed it from the other account?
