Migrate to 2010 Exchange, Distribution groups wrong.

We recently migrated over about 500 mailboxes to Exchange 2010 from another domain.

Some of the users have set up their own distribution lists on the old exchange server.  While they were brought over, any internal names are still trying to access the mailboxes by the name of their location in the old exchange server.

Is there any way to automate updating these lists? I am sure we could just delete and recreate, or even export, fix, import, but both of these would take days with all these users.

Thanks for any suggestions.

What are these DLs? Were they in the old GAL or were they within user's Contacts folders within their mailboxes? (Personal DLs)?

Have these DLs been migrated over and if so how?

They were in the users Contacts folders.

We did an exmerge of the data from the old exchange server to the new one.  I am not sure if these DLs would have been included in that or if not.  I assume so unless the users exported and imported them.

I am sure exmerge would of copied them over. What do these DLs contain? Other contacts from the users Contacts folder or contacts and mailboxes from the GAL?

The DLs contain both internal and external addresses.  All the external ones go out without issue.  The internal ones bounce, saying of course they can not find the mailbox at the location they were on the old mail server.

Import the old legacyExchangedn values of the mailboxes onto the new mailboxes as X500 email addresses then then DLs will work and replying to old emails.

That script looks great, and I have exported the aliases and x400 addresses from 2003 exchange.

When I try to import them into 2010 however I get an error:
Property 'EmailAddresses' cannot be found on this object; make sure it exists and is settable.

I think the script needs slight modification to work on Exchange 2010, try the one below
Import-CSV d:\sbs.csv | foreach { 
$Temp = Get-Mailbox -identity $_.alias 
$Temp.EmailAddresses += “X500:” + $_.legacyexchangedn 
set-mailbox -identity $Temp -EmailAddresses $Temp.EmailAddresses}

Open in new window

Can you post the first 2 lines of your csv file?

If you try get-mailbox -identity <alias from file> does it return anything?

That's not a legacyExchangeDN

legacyExchangeDN's look like this:
/o=Orgname/ou=AdminGroup/cn=Recipients/cn=MbxName

Find AUser's with ADSIEDIT and then put it in the file and it should work

Alright, trying to import the correct values now, but still getting the error:

try it with just 2 lines in your .csv file:
1.) the header line (alias, legacyexchangeDN)
2.) alias and legacyexchangedn of the mailbox

can you post the first 2 lines of your csv file again please?

Does the object you are trying to add the X500 address to have e-mail addresses?

If you type
get-mailbox -identity auser |fl DislayName,Alias,EmailAddresses

does it return value for DisplayName, Alias & EmailAddresses?

sorry that should of been DisplayName

Are you typing in the script manually into EMS or have you created a .ps1 file? It should work either way, I have tested it both ways and it is adding X500 addresses to my test mailboxes...

We tried a ps1.

If we use the following just typing it in it works:

$Temp = Get-Mailbox auser
$dn = "LDAP://" + $Temp.distinguishedname;
$obj = [ADSI]$dn;
$obj.ProxyAddresses +=  “X500:” + thepath
$obj.setinfo()

paste this code into say AddX500.ps1 put it in directory called maybe c:\X500

Change the path to the .csv file in the first line so it matches where your. csv file is, maybe put it in c:\X500 too

then open EMS on Exchange 2010 and type
c:\x500\AddX500.ps1
then press enter
you shouldn't get any errors
then do
get-mailbox -identity auser |fl DisplayName,Alias,EmailAddresses
and the user should now have an X500 address, do they not?
Import-CSV d:\sbs.csv | foreach { 
$Temp = Get-Mailbox -identity $_.alias 
$Temp.EmailAddresses += “X500:” + $_.legacyexchangedn 
set-mailbox -identity $Temp -EmailAddresses $Temp.EmailAddresses}

Open in new window
