Hi SKS,
Can you clarify if you are setting up an exchange account or just an IMAP connection?
Regardless, once you have your app open, select sync options and chose the duration you wish to sync your emails. This is truly up to you. I leave it as 2 weeks since i usually have internet access and would prefer a light running data file.
Let me know if this works. If not, select your settings, go to the mailbox you setup and then under data usage you can set the duration for the data to be synched.
Hope this helps.
