KB for known troubleshooting experiences with Google Apps for Business mail collection:

Before performing this task.  You will have ensured that the configuration between the Sonian Archive Collector and Google Mail is correct and successfully working. (Correct username and password combinations).

Mail in the journal mailbox is not being collected.

If, after configuring the POP3 Collector on the Sonian archive service and you have logged onto the the 'Journal Mailbox' to confirm that mail is definitely being copied to the journal mailbox, you may want to reset the the POP access options.  This event has occurred where the mailbox seems to have automatically defaulted to 'Enable POP for mail that arrives from now on' despite it showing as POP is enabled for all mail

  1. Log in to the newly created mailbox and go to Settings > Forwarding and POP/IMAP > POP Access

  2. Click the Enable POP checkbox to enable POP for this mailbox (if not already set)

  3. Ensure ‘Enable POP for all mail (even mail that has already been downloaded) is selected.
  5. Save the settings.
  6. Attempt to issue a collect now from the Sonian Archive Portal

If still failing to collect all mail, except the most recently journaled mail

  1. go to Settings > Forwarding and POP/IMAP > POP Access
  2. select Enable POP for mail that arrives from now on
  3. Save settings
  4. Then set ‘Enable POP for all mail (even mail that has already been downloaded) is selected.
  5. Save settings
  6. Perform a collect now from the Sonian Archive Portal
