I work for company X.Company X owns company Y.Employee Z does work for both company X and Y.Z wants to be able to send emails through Outlook on the both domain X and Y. IE: she wants emails Zz@domainX.com and Zz@domainY.com to both come to her one workstation and outlook client and operate independently. So if she gets an email to Zz@domainX.com the reply is from Zz@domainX.com; the same being true for Zz@domainY.com.We're running Exchange 2007.Is this even possible? How?Thanks.

I'm a bit dizzy. Seriously, though, this type of requirement is not uncommon. However, it is NOT as simple as you might think. If you sent an e-mail via Outlook, the Exchange server always wants to put the primary SMTP address for YOUR account on to the "reply address". I think the bottom line is that the user is going to have to have 2 mailboxes and is going to have to check 2 different accounts. If you have a trust relationship, you can give her X\Z account permission to your Y\Z mailbox, then she could always be logged in to domain X. Then, create 2 Outlook profiles. One for Exchange X and one for Exchange Y. The user will have to close Outlook and then select the other one in order to check the other mailbox. Without some coding, I don't think you have any other options. I could be wrong because I usually tell clients to try and avoid this type of configuration since it makes things a bit more complicated, but sometimes organizations need to do it anyway.

So, essentially, I'm best off just telling them that they have to rely on aliases and explain why replies to Zz@domainX.com are coming from Zz@domainY.com?

Well, it is my "opinion" that is probably the best approach. You have lots of options (the 2 mailbox option) or giving the user "Send as" permission to the other mailbox and having him/her always change the From if they are replying to a message that was sent to the other mailbox. But, it will be additional work on the part of the user. The bottom line is that there is NOT an "automatic" solution for the user. Unfortunately.

Ok.I added Zz@domainY.com to the emails of Zz@domainX.com. So that would make all Y emails go to X. Simple enough.Then I tried to give X the send as permissions of Y. I did this through AD, but I didn't have the actual DomainY account made in exchange, just the alias. I tried to send as Y from X and said I didn't have the permissions. So then I went into exchange and tried to create just a new user. I tried to give it the email Zz@domainY.com and it complained that it was already being used by Zz@domainX.com... which it is.That may be too much info, but I think it better than too little. So, how do I have the email sent to Zz@domainX.com from Zz@domainY.com and get the send as permissions to send as Y from X?I think this was a bit much for my third day.

This sounds similar to my query in my thread... http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=3832062&SiteID=17 They're must be a way to access two email addresses from two different domains via one Exchange account. and also be able to send as from your choice of accounts...

Yes and no.My work around was to make a second account with the second domain and have it disabled. I had the mail set to that account forwarded to the primary account and then I gave the primary account the ability to send as the secondary account. Then I set up a user rule in their Outlooks that would place all the mail from the second domain to a new inbox so they'd know they had to use FROM: to send as the secondary email.Ugly, but it worked.

Sounds like this could work for me... I'll forward this to my admin and see if he can implement it. Only problem I see is in using OWA. That is, logging into the secondary accounts OWA will have no email in their (as it has been forwarded to the primary account). So it will not be possible to use OWA to reply as the secondary account to emails sent to the secondary account. Since you have no emails in the secondary account inbox to reply to, and also becasue in OWA in the primary account, their is no way to choose FROM. Or is there a way around this? EDIT: Is it possible to have SENT ITEMS forwarded from the secondary account to the primary account? Or is it only possible to forward incoming emails? Below is my mapped out solution, but I think their will be an issue with Sent Items; Account A: ryan@a.com, an Exchange account. Account B: ryan@b.com, a pop3 account (or exchange account if required) emails sent to B are automatically forwarded to A. Forwarded so that they appear to be from the original sender. Setup Account A so that it has rights to send as B from A. This is easy via FROM option in Outlook, but I believe impossible from OWA? So then when away from Outlook I will log into OWA for A and all inbox will be fine. Problem will be however with sending FROM B whilst using OWA for A. I could log into OWA for B and send an email, but then this sent email will not appear in SENT ITEMS in A. Thus why I'm asking if it's possible to have SENT ITEMS elegantly forwarded to SENT ITEMS in A. This is doing my head in. All I need is to be able to receive and send email from different email addresses via one exchange account. But I also need to be able to do it from OWA for when I am away from my PC with Outlook on it

Is this any help?http://www.ivasoft.biz/choosefrom2007.shtml

Thanks for that link. I wonder if it works with OWA. If it does, then I might speak to my admin about it. If it doesn't work with OWA, then I can do exactly the same using Outlook and choosing a different email address from the FROM field. I can't beleive MS hasn't got an elegant way of doing what I need. Surely I'm not the only person in the world who ha multiple email address from multiple domains and wants to manage them all via one exchange account?! This is driving me crazy.

Well, in my searching, I've found threads about this over 7 years old... so yea, it's been a problem for some time, just not big enough to warrant a proper fix.

Will pop collector help me out at all? i.e. does it 'deliver' emails from all folders in the pop account? or does it only deliver emails from the pop accounts inbox? If I could configure it to 'deliver' emails from sent items etc. then it would work a treat for me. Also, when pop collector 'delivers' emails, does it deliver them so they appear to come from the original sender? or do they appear to come from the pop account they were delivered from? I could then have pop acunts for all my secondary email addresses and have a pop collector fetch emails from these accounts. I would then be able to send emails via any of these pop accounts in outlook. If I was away from outlook, and I needed to send an email from one of these other accoutns, I could log into pop webmail and send an email from there. I could then have the pop collector fetch this sent item from the pop account and put it in the sent items in the exchange email account. (that's assuming pop collector can fetch emails from folders in pop accounts other than just the inbox)

I dunno. I've already started causing more problems.
