Our organization is at about 170% of our data storage limit. Is there any consequences of this? Or will Salesforce just not care about the limit?
I believe If you do not get your storage use down to within the limit you will be contacted and asked to purchase additional storage and potentially you could be unable to perform any more DML until you are within the limits.
I am not sure of the tolerances and it is completely up to salesforce when they choose to enforce the limit.
