Vodamail Email Crash

Morning, the email address for the Vodamail account linked to this mobile number has *******ed and I cannot clear excess emails. Please can this be reset to allow this. Excess emails can be cleared so I can access the inbox and clear further emails to allow for space. I am available this weekened and then from 6 July to take your call. If you can fix the mailbox, I can reset the password and access via my mobile phone.
