Hello,

We have Exchange 2010 and some of our mailboxes through the Exchange management console have Custom attribute 1: 6446 and Custom attribute 7: domain2.com

Questions:
1. Do you know what is 6446 ?

2. How can i check and remove the Custom attribute 7: domain2.com via exchange powershell ?

Thanks for your help...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It's something that was added manually or through some application that uses those Custom Attributes. Has nothing to do with Exchange. It's AD-related attributes, they were there BEFORE Exchange was installed in the organization.

I guess Question 1 is answered. Thanks Ronin.

Do you have multi-tenant configured on your Exchange?

Hmm, multi-tenant ? Not sure what you mean.. sorry i am not an exchange guru
RoninCommented:
multi-tenant is hosting multiple companies on a single AD infrastructure. In such configurations, various users stamped with the corresponding domain name in some attribute. Different users, different companies will have different domain names.
namergSystems AdministratorAuthor Commented:
Same company but multiple email addresses.
RoninCommented:
You might be using Address Book segregation, that's why that attribute populated with the domain2.com.
Check some other users, see if any others have a different FQDN. Use PowerShell for that.

Hmm that is not the answer to my question though
RoninCommented:
Set-ADUser –Identity user -Clear "extensionattribute2"

Open in new window

namergSystems AdministratorAuthor Commented:
Hmm I need to do it for 100 uses :o
RoninCommented:
Get a list of all your users from AD, you can use either username or alias.
And execute:
foreach ($x in (Get-Content C:\Temp\list.txt)) {Set-ADUser –Identity $x -Clear "extensionattribute2"}

Open in new window
