Outgoing mail blocked and strange storage behaviour

Outgoing mail blocked and strange storage behaviour

Hi,

One of our users got blocked from sending email because of

Reason for the block: Daily Mail Size Quota Exceeds Limit

However, we have only been using the service normally as usual. 

When we checked our mail box size, all of them are in strange number like -154260800% of 0MB

The email with issue is ci@omediamacau.com

Please advice.

Thanks,

Michael
