Hello community,I am not exactly sure, if this is the right forum, but Iwill try it here.We are setting up a new Exchange Server 2007 in our organisation.This exchange server should work for 3 companies. Company 1 is our main company and everyone is employed in this company. the other two companies are subsidaries and so some of the employees have mail addresses for all 3 companies. In the AD we only have one user for the person and we can create a mailbox for each user in the AD.Then we assign all necessary e-mail adresses (name@company1.de, name@company2.de, name@company3.de) Receiving all mails in one mailbox is no problem. But there is only one primary SMTP address for outgoing mail, so the person would always send the mail from name@company1.de.Is there an easy way for the user to change the address he wants to sent from?It works, when we create one User in the AD and a mailbox for each User/compay combination, but then there twice as much users in our addresslists.Regards,Alexis

Hi Alexis,It is not possible in Exchange 2007 natively to choose different Send As address which is secondary smtp address of the same users.Workaround is to create different user or mail-eanbled public folder to use multiple smtp addresses or you may need to use some third-party utility to get this functionality but that might be costly :)http://www.ivasoft.biz/choosefrom2007.shtmlAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Hi,If you use POP3 client, sending from different email address is supported since mulitiple accounts could be configured in POP3. If not using POP3, that is impossible unless implementing the operation as Amit suggested.ThanksAllen
