mass mailbox-enabling....EXCH2007 SP1.....all user account objects to be mailbox enabled are already created in one specific OU

[Cary Shultz]

Good evening!

I have two questions regarding the subject line:

1) the organizational unit in which the 185 user account objects reside has
the following path: "OU=MyOU, OU=Active Accounts, OU=MyUsers, DC= , DC=".
If I am using the "get-User -OrganizationalUnit" CLI do I simply enter
"get-User -OrganizationalUnit MyOU"? So, the entire entry to mass mailbox
enable all of the user account objects in that OU would be:

Get-user -OrganizationalUnit MyOU | Enable-mailbox -Database "EXCHx64\First
Storage Group\Mailbox Database"

2) What happens if someone has already created about 35 of these mailboxes?
Does it simply tell me that the first 35 failed to be created because they
already exist and it will create the other 150?


Situation is that we have to create 185 mailbox-enabled accounts and the
Help Desk has already created the Windows user accounts (all 185 of them)
and put them all in a specific OU. Now, they are creating the mailboxes.
They have manually created 35 or so of them. I am thinking that it would
be a whole lot faster to use the built-in tools but have never done this
(always creating onesies and twosies).

Thanks,

Cary

That looks about right.

You'll get a failure on the 35 that already have mailboxes. The reset
will succeed. If you want to eliminate the failures (assuming you
don't have any mail-enabled users in the OU), make a small
modification to your pipeline:


Get-user -OrganizationalUnit MyOU | where {$_.RecipientType -ne
'UserMailbox'} | Enable-mailbox -Database "EXCHx64\First Storage
Group\Mailbox Database"

Be cautious with the "get-user" cmdlet -- it'll get "service accounts"
(like IUSR_servername, krbtgt, etc.) into your 'enable-mailbox' stream
if you aren't careful. :-)

Thanks, Rich! Looks like I do remember a few things....

And, good point on the "Get-User" pipe.......It *could* be super dangerous
as you mentioned. In this particular case not so dangerous....
