Exchange 5.5 and pop3

Locked

I have a client who had an Exchange5.5 server (NT 4.0) setup for them before I came into the pic. Their Ex5.5 is used for calendar sharing and little else, as their emails are hosted off-site via pop3. Here’s the problem:
When a user goes off-site and dials to the Internet (AOL), they can recieve email (OUtlook 2000)from everyone EXCEPT those emails being sent to them from the home office. The “office email” will sit on the Exchange server until the user reconnects to Exchange and viola!: There are the office emails. Obviously, Exchange is not pushing emails out to the net and I am trying to figure out WHY. My thought is that the Internet Conn Service is not configured correctly? Other than sending email to the “remotes” all worksquite well.

I hope this is enough info but as things go, it’s probably not 🙂 Any tips would be greatly appreciated.

Thanks!

Exchange will not route email that is addressed to a local user outside the exchange server, since you clients are downloading thier email from the hosted pop server (and not you exchange server) it dosn’t show up.
If you want to stay with your ISPto host your email and everything else should work, you whould have to stop using POP on the clients computers instead use a pop client on the server that downloads your email to the exchange server. For the clients that have to connect remotely so they can download email. Setup pop on your exchange server.
You did not mention how email is sent from the office out onto the internet. If you use your exchage server to send the email there shouldnt be any problems on this. But if you use your ISPto send the email to the internet you will have to change this as well.

My guess is that the exchange server has not been ‘told’ to send the messages to the outside world. If the mailbox smtp address is the same as the external pop3 address the the MTA will put the messages into the mailboxes. If this is the case the way to send them on from there is to change the internal smtp addresses to something like username@here.local, You can do this at one go from site addressing. Then create custom recipients for each user with the external address, again you can do this at once by creating one, then exporting the directory(Tools,Export) and only select custom recipients, If you then open the CSV file as a spreadsheet you can copy the layout of the first one and change the usernames,smtp address,and X400 address in each subsequent ones. Save the file back as a CSV, then open the same file in notepad and add a to the end of the text, otherwise the last entry in the CSV does not import correctly.
This done you can import the file into the exchange directory (Tools,Import). If you create a new recipient container for these it will make future editing easier, Then you can set the appropriate Custom recipient as the alternate delivery address for each user. Now the MTA knows that these addresses are external and each one will be sent on to the IMC. After setting up the alternate recipient Hide all the custom recipients from the address book to prevent them appearing in the GAL.

Hope this helps
