MISSING SENT EMAILS IN OUTLOOK - EXCHANGE 2010

i HAVE A SINGLE EXCHANGE 2010 INSTALL AND I HAVE A FEW USERS THAT HAVE BLOCKS OF EMAILS MISSING FROM THEIR SENT FOLDERS.  I JUST RESTORED ONE USERS AND 2 DAYS LATER THEY WERE MISSING AGAIN.  I CHECKED THE SERVER AND THERE ARE NO RETENTION RULES SET.

Are the deleted emails the oldest in the sent items folder?
Are all the deleted emails for all users the same sent date range?

Are the users in question using mobile devices that use Exchange Active Sync?

this particular user is right now missing december 11 to yesterday.  i have not checked other mailboxes.  this user does not use a mobile device.  i will check a few other mailboxes.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

When the user sends an email, does it actually get saved to the sent items folder?

Check options.
File / Options / Mail - Save messages - Save copies of messages in the Sent Items folder

Does the user only have one mail profile in Outlook?

yes, it is a basic exchange/outlook setup with no modifications.  a single profile

I have been informed this has happed to a few others, but not everyone.  just large blocks of email go missing from SENT folders. this sia fairly new install of Exchange, no other know issues.  Exchange 2010 on Win 2008 64 on an ESXI 5 host.  90 users, 160GB of mail storage, plenty of disk space.  12 GB RAM.  all other functions work well.
Experts Exchange has (a) saved my job multiple times, (b) saved me hours, days, and even weeks of work, and often (c) makes me look like a superhero! This place is MAGIC!
