Powershell : find and move disabled computer account.....Active Directory cleaning

Hi mates,
I needed to perform some active directory cleaning.
The most important consideration about this activity is that most of the modern software are continuously in touch with AD, querying it, retrieving data and so on.

To have a partial clean situation we putted in production another script that disables the computer accounts that do not logon to the domain from 90 days.
Having a lot of disabled computers we would like to optimize also the vertical software that rely in AD.

Powershell disable users that don't login to domain for XX days

Hi mates,
I had the need to disable old/zombie users since my friend's active directory was not maintained in a clean state. Something easy : query AD with some exclusion, an email with an attachment to recap everything. More explanations later....in the meantime customize and enjoy.

Exchange 2003 & mailbox queries.....no powershell

We needed to query AD from Exchange 2003. We know that this version is not fully "queriable" by powershell.
I'd to understand how to retrieve some important information. We had for example an archiving system that use the group membership to "understand" if your mailbox is "storable" or not.
I took the opportunity also to grab other useful info .....let's see
Why don't use AD query tool ?
