When messages from PST are dumped into a users mailbox they are not exporting, while other messages in the mailbox have been exported. No changes have been made to the policies or the mailbox in question.
The messages from the PST are older than the last processed message in the folder. Archive Manager sets a folder date stamp when it is finished processing a folder. If messages older than this date stamp are placed in this folder, they will not be processed.
1. Open SQL Query Analyzer
2. Type Use ArchiveManager and Execute
3. Find the mailbox id for the mailbox in question.
4. Type select mailboxid from mailbox where name like '%firstnameofuser' and Execute. This should return the mailboxid
5. Type Update folder set lastpopulateddate = null where mailboxid = mailboxidnumber. This will set the dates to null and thus process the messages on the next pass.
Running SQL commands should never be taken lightly. If you have a DBA, you should have them understand what you are trying to do before executing SQL in Archive Manager. If you need help, please contact Quest Support.
