Thank you for your answer, i'll try to be more accurate (I'm french, i'll probably make some gramma mistakes though...).
First of all, i've not access to the server through ssh, i can only manage it through the admin web page (the administrators and hosters roles are splitted in kind of a strange way here..), so i won't be able to tell you the output of the command you suggested, i'll ask the hoster to do so..
My connector version is 6.0.7. The server version written in "About Zimbra Server" on the web interface is "Version 6.0.7_GA_2476.RHEL4.NETWORK".
There is a bug report seems to be close to my problem here :
Bug 46521 – When sending from a persona within Outlook, the sender address shows within the TO: section within the sent folder of the Web UI
I don't think it's necessary to open a support case since it is EXACTLY the problem mentioned earlier by mjdl.
I'll describe my exact situation :
There's a mailbox which is used to answer to send newsletters and other things. I shared this mailbox with the users concerned, and allowed them to reply using this address.
On Outlook, they are getting the mails, but when it comes to replying, the mail is send using their own mail addresses (In french it appears like "user@domain.com de la part de
persona@domain.com", which is probably the translation for "user@domain.com from
persona@domain.com").
So, i created personas on each of their Outlook, and now, they have access to a drop down menu where they can choose the persona used for the reply.
The thing is, therefore, our configuration was made in such a way so that the sender was automatically set (we used IMAP and SMTP server).
Now, they are constantly mistaking, and they are blaming us (we changed the way they worked, i can understand).
So the question is : Is there a way to automatically respond using the address of the shared mailbox instead of our own ?
Or is there a way to configure personas depending on the folder it is sent from ?
Thank you, and sorry for my english.
edit: Most of the users are using Outlook 2007, some are using Outlook 2003, but I didn't tried with this version yet.
