Exchange 2013 Several Mailboxes on Different Domains

18 posts in this topic

Hi everyone,

 

I got a situation where we have several domains on the AD.

 

d1.com

d2.com

d3.com

 

and others...

 

When joining  a computer to the domain and launching outlook, it autodiscovers the user and adds the mailbox to their outlook.

It also adds any other mailboxes the user has access to.

 

so:

 

user@d1.com would be their default account

and they would also have access to:

user@d2.com

user@d3.com

 

I can configure to do a from: user@d2.com through outlook which is find, but the sent email seems to go onto the sent items of user@d1.com for some reason

 

Any calendar invites will go to user@d1.com even though it was sent to user@d2.com or d3.com

 

Any ideas how outlook could recognize the different accounts and manage the calendar requests and sent items to the correct mailbox?

 

Cheers :)

That's expected as Exchange can only have one "from" or primary account.

Damn, just strange that you can have access to other mailboxes and access rights to "send as" but it just wont put it on the correct folder

I was on my phone so figured i'd post later so here it is.

 

Your only real option is maybe external mail enabled distribution group or Shared Mailboxes.

 

So in this case you'd have:

 

user@d1.com - user mailbox

user@d2.com - shared mailbox

user@d3.com - shared mailbox

 

user2@d1.com - user mailbox

user2@d2.com - shared mailbox

user2@d3.com - shared mailbox

 

ETC.

 

You'd then give user@d1.com SEND AS permissions to their corresponding D2.com and D3.com mailboxes.

 

You can then setup forwarding on user@d2.com and user@d3.com to forward all emails to user@d1.com

 

The same would be for Distribution Groups except adding the user@d1.com as a member of the group instead of forwarding.

 

Sent items are a different story and it depends on which version of Exchange you are on. In 2010 there is a server side change you can make to automatically put the emails in the right folder based on the sender ID. On Exchange 2013 it's a local change on the user machine (registry) to force Outlook to put it in the correct sent items folder.

Thanks Roger.

 

Correct me if I misunderstand.

Wouldnt all the emails go into just one mailbox? e.g. user@d1.com

 

The users would need to have emails on the separate mailboxes if possible without replicas :(

Well you can then disable the forwarding to keep the emails separate if that's what you prefer. Obviously this might create some confusion for users when it comes to locating information if it could be in 1 of 20 different mailboxes. If it's only say less than 5 it might be management but remembering to SEND AS using the correct email address too might become troublesome if you have tons to choose from each time you send and email.

 

I'm waiting to see if Budman and sc302 can provide something better as well - i'm sure sc302 is probably typing right now :p

You need to adjust your rules.  You have let the default rule define all users.  This has been the same since 2007, there isn't much difference between versions. 

 

IN the emc go to Organization Configuration, Hub Transport, E-mail Address Policies, make new policy and change the default policy.

 

You will probably have to enter in an identifier that the policy can pick up, company name for instance.

Before I say anything - NOTE: I work for this company.

 

Take a look at Exclaimer Email Alias Manager, it allows you to choose which of your email aliases you have on your Exchange account when sending email.

thanks Jamie, the price of the app is a bit steep for the amount of users :(


thanks sc302 :)

I'll give it a try and see what I can do, any chance of a URL that might give a tutorial on how to do it as my knowledge is not advanced?

Thank you for the feedback.  How steep is too steep out of curiosity?  I'm not in a position to necessarily do anything about pricing but it's invaluable feedback nonetheless.

It is very easy to do. Time consuming yes. Take a user enter a company name in the user profile that has striving to do with the domain name so it is easy for you to remember, then follow the bouncing ball to create the rule.

I have a way to make a mass change in ad but first test the rules with the modifications you make.

what I am suggesting isn't hard and can be done for far less than 100 quid per box...hell I will take 100 quid just to make the rules for you, it won't take much more than 30 minutes with the use of admodify (allows you to mass change ad with a few clicks) but don't want to do this until 1 mailbox is setup and tested properly.

never miind what I wrote, I completely miss understood what you wanted.  Why do you have multiple mailboxes, why not one mailbox for all addresses?  each mailbox is seperate from eachother, you would have to send the calendar invite to each mailbox user.  It really doesn't make sense why you are seperating it this way.
