I have read over the entire sticky of "Item synchronization issues" as well as almost all the documentation but couldn't find this, so I apologize if this is documented/posted elsewhere.

My question is how does Data Sync determine how far back items in folders get sync'd. Is it based solely on the configuration of the mobile device? Is there a way to make it behave like a traditional IMAP connection and sync the entire contents of a folder regardless how far back you go?

For example on an iPhone, I don't seem to be able to get mail sync'd further back than 200 messages, regardless of folder since that is the max setting on the iPhone. On my android the max setting is 1 month with the same behavior.

I have administrators looking to populate their personal folders with older email but it doesn't appear to be possible. Is this working as designed?

Thanks for the help!
