To start out an interactive session, merely kind:

[LazySrvLab02]: PS C:>

Now you can run PowerShell instructions on the server, simply as in case you are working immediately on the server. If you might want to authenticate with totally different credentials, then use the parameter -credential to specify the username that you just need to use. You’ll be prompted for the password.

To exit the distant session, kind Exit-PSSession

The grid view output is a good resolution to that. It’s going to output all the info in a pleasant searchable, sortable view in a brand new window. The desk comprises all columns, which you’ll type and search by means of.

Get-EXOMailbox | Out-Gridview

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:

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.

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


We just about all know the ping command, a straightforward and simple command to check if a community system is on-line, and what the latency is for instance. However there’s additionally a PowerShell variant, which is a little more highly effective.
