Over the weekend I was archiving a user mailbox manually. I didn't notice until now that it didn't archive the sent items. I also noticed that they are also no longer in the live mailbox. I'm not sure where they went to. I have to archive about 4 years worth of emails and i did them in 4 month increments for each year (ie, 2008-jan-april, 2008-may-aug, etc).
All of 2008 and 2009-jan-april i see sent items, but everything after that i don't see any sent items. and some of the archives dont even list a sent item folder.
I archived using the same settings, just changing the dates.
I'm at a loss.
