There may be large emails that are being downloaded. There may also be a POP lock on the mailbox. A POP lock is a mailbox lock that usually occurs due to the following reasons:
  • Mail is corrupted
  • Mailbox is substantially large
  • Mailbox has received a large attachment
  • Interrupted download of messages
  • Anti-Virus scanning.
If you believe your mailbox is POP locked, contact our Help Desk.
