On my BB Storm, I have several pop emails, yahoo mail and gmail - and also my two work addresses that I access using BIS (not BES). For my two work addresses, I use Outlook on my PC as my mail client. One of them comes into Outlook via Exchange and the other comes in as a pop account.
My work emails come to my phone just fine. But, when I get to work, and mail in my inbox that was received overnight shows as unread in Outlook and are again sent to my phone (as though they are new messages). So, I get them as duplicates. This is only when first logging in to Outlook for the day. During the day, things are fine - no dupes.
Is this just the way it is, or do I have something set up wrong somewhere?
