It´s not searching emails in the search option of messages

Hi Support,
Once month ago my email account ( ahidalgo@optimice.com.pe) was blocked for full space reasons, now the account is enable but the search option of messages basic and advanced are not filtering correctly the messages.
could you please help me to activate this option again?
Thank you.
