Remove Exchange Attributes using Power shell –Exchange 2010

At times we have to Remove Exchange 2010 Attributes for a Corrupted Active Directory Account

Its been a tedious job to go and change every Exchange attribute to not Set,To Create a New mailbox for that Particular Active Directory Account

Also in some scenarios when Exchange 2010 Server Crashes. We have to remove those Attributes to recreate Mailboxes for those disconnected Active directory account. Where we won’t be able to create mailboxes for them

Unless we clear those Exchange attributes

If disabling the mailbox works it does the same task in the background.

To Simply the task and Save Time.

Simplified into a simple script. Where we can set the Exchange attributes to Null in one shot for a Specific User.

So Lets See how to do it.

Running the Script, It will ask you to Enter the Alias of the Users Active Directory Account

Download the Script

Now Manager Active Directory account is Free from Exchange attributes

We can create a New mailbox for him without any harm

Be Cautious that You will be losing his mailbox settings. which cannot be recovered

It makes the Following Attributes to “not set” or we can say as Null
