Duplicate Emails

Hi

I have a small business 2003 server running Exchange. However, Exchange uses the POP3 connector to retrieve emails.

All users in the office don't have a problem with duplicate emails.

Remote users who have Laptops have their Outlook configured so that they have an Exchange mailbox which is the default store. This uses .ost file to keep the Exchange server up to date when the user either comes into the office or connects using a VPN to synchronise. However, in order for the user to get their emails whilst not connected to the Server they have an additional email account setup which uses POP3 to collect their emails. These are downloaded onto the laptop and into the .ost file (not a separate .pst file).

When the remote person does synchronise they receive duplicate emails. Any odea why?

Thanks

Its because the mail is downloading from two accounts into the same OST file by the sounds of it.

To get round this I would look at getting rid of the POP account and setting up Outlook Anywhere (HTTP over RPC).  The users will be able to access the emails from outside the office via the exchange mailbox without having the additional POP account.

You will need to open ports on your router if you haven't got them open already.

Hope that helps a little.

Hi

I have considered HTTP over RPC but in SBS 2003 it is a bit of a pain to setup.

However, only 1 account is actually connecting to the POP3 mailbox and downlaoding the emails. This is then stored in the .ost file. The exchange server does not download emails for the remote users?

Because its SBS, I believe that it should be setup by default... I coulpe be wrong about that but I only remember ever having to set it up on Exchange Server 2003, not SBS.

The POP3 account is using the same OST file to deposit mail, so when the laptop connects to the exchange again it syncs everything from the last sync date pretty much.  Thats probably why its duplicating.

HTTP over RPC is the best option I think.
