Hi,
When trying to send an email from any of my outlook accounts I am getting the below error message but can not see what I need to do to resolve it:-

Your message did not reach some or all of the intended recipients.

  Subject:  
  Sent: 30/09/2021 10:24

The following recipient(s) cannot be reached:

  '@outlook.com' on 30/09/2021 10:24
        554 5.2.2 Mailbox full. Visit https://aka.ms/mailboxfull for more information.; STOREDRV.Submission.Exception:QuotaExceededException.MapiExceptionQuotaExceeded; Failed to process message due to a permanent exception with message Cannot submit message.

Any idea's on how to resolve this would be appreciated,

Many thanks
