Outlok can NOT send emails over a Public or ANY other folder any additional, sub or additional Personal Folder. This is not possible with Outlook and not with Exchange Server.
How can you solve this function?
(Some definitions are maybe wrong, because our english is not perfect and we have german Outlook versions)
A.) For Microsoft Outlook 98 and Microsoft Outlook 2000
Create a rule for all incoming emails on the clients: "move all incoming emails into the "Public Inbox"" or you can also create all personal email accounts in the "server Outlook" and move the incoming emails into for all users seperate created subfolder/inboxes.
Sent email:
Creat a rule on all clients:
"after sending an email make a copy of this email into the "sent items folder" of the Public ShareFolder server".
You will find the Rules Wizard in Outlook under Tools/Rules Assistens.
You can also create for every coworker an own "sent items folder" in the shared PST file and then you can create for every user an own rule. The everybody can see who has anserwed which email.
B.) For Microsoft Outlook 2002 and Microsoft Outlook 2003
For incoming emails you can create in the Outlook on the Server all email accounts, also the Personal Email accounts. You can move this incoming emails by Rules (Tools/Rules Wizard) into seperate inbox folders (Outlook supports additional folder).
Example:
Public Inbox
Public Inbox User 1
Public Inbox User 2
Public Inbox User 3 etc.:
In Outlook under "send/recieve/Transmissiongroups/Edit" (You get this windows also if you use "Strg+Alt+S" and click here on "Edit"), you can select for every email account "download" or "sent emails".
On the server you select for all email accounts "Download" but NOT send emails. On all clients you select for the personal email address "sent emails" but NOT download.
This works only with internet povider without a SPA authorizing (ask your provider if he needs SPA).
It is a little bit work, but this is the way for Outlook to support this function.
