Set-StrictMode

The Set-StrictMode command in PowerShell establishes and enforces coding guidelines. By default, strict mode is turned off and that may trigger an actual mess. When strict mode is off, PowerShell threats uninitialized variables as $null or 0, for instance.

Notice the next code:

$username="adelev"
Get-EXOMailbox $usename | Set-mailbox -Hiddenfromaddresslist:$true

Within the instance above, I’ve misspelled the $username variable within the Get-ExoMailbox command. If Strict Mode will not be enabled, PowerShell will deal with the misspelled variable $usename as a $null, with the end result that the cmdlet will get all mailboxes and conceal all of them from the handle listing.

Once you set StrictMode to model 2, PowerShell will as an alternative throw an error that the variable will not be set.

Set-StrictMode -Model 2

I like to recommend including the Set-StrictMode -Model 2 command to your PowerShell Profile.
