Migrating email from one AD account to another

[shine_victim]

Hi all,

 

Quite possibly an easy fix but I am personally at a lose at the minute!

 

The scenario is, we have recently migrated an email address from one AD account to another.  Easy peasy!

 

Now, all external emails are coming into the new account fine but any internal emails are still being received by the old account.

 

This has surely got to be the x400/x500 addresses pushing the emails to the old account.

 

My question is, what the best way to clean up these old addresses etc to allow mail to flow to the correct location?  

 

• Simply remove x400 x500 from old account and add them to the new account?  
• Get all users to download a fresh copy of the Global Address List and remove autocomplete address from Outlook?
  • If this is a the option to go for can we force this to happen via Exchange at all?

Thanks in advance guys.

let me see if I understand this

userA@domain.com is your old mail address going to userA.domain.local

now you have a new domain called newdomain.com which is also pointing to userA.domain.local but you have your old mail userA@domain.com going to userA.domain.local and you want to fix this so that userA.domain.local receives emails for userA.domain.local? 

 

Internal emails have nothing to do with external emails.  If anything you want to setup forwards from one email address to the other or have the other answering for all emails (internally and externally) for the new mail address. 

 

When someone changes their name, we change their name in AD and user ID in AD and make changes to their smtp and x500 on the exchange server side so that they receive for both their old name and their new.  I think that is what you want to do in this instance.  The issue comes into play with outlook cache when not doing this, everyone on site will have an issue sending if they allow outlook to auto fill in based on their cache settings.  They have to delete the mail account in outlook cache to be able to send to the new address.   another option would be to forward the old mail account to the new on and hide the old from the address list.

Yeah I am bit confused what you did as well.

Lets start with sc302 example

"userA@domain.com is your old mail address going to userA.domain.local"

The way I read what you did, is you now you have userA@domain.com, being delivered to userB.domain.local mailbox..

Did you create a new account and mailbox? Why not just give userB account access to the mailbox userA was using?

If you needed userB to access userA mailbox - why did you not just give userB access? And nothing would have to have been done on the external side?
