A user has recently been migrated from 2007 to 2010 and there has been an ongoing issue with emails in her sent folder dissapearing.
I've checked the auto-archiving and that isn't an issue.
Her profile has been blown away and recreated with no success.
The emails that dissapear ar eboth internal and external and don't seem to have a logic.
I checked today and there are sent items from today however there are a fewe random one's that have just dissapeared.
Any help would be appreciated!
