Function for locating an email address

Function for locating an email address

Yesterday I was given a relatively easy task: find out who or what has a given email address.
As this was within our own Exchange organization it proved to be quite simple:
You can achieve the goal with a simple one-liner:

get-recipient -ResultSize unlimited | where {$_.emailaddresses -match ""}

But wouldn’t it be easier to have it in a function? In Powershell, creating functions isn’t all that hard. Basically all you need to do is wrap the command or script block with a function statement, see here:

function Get-EmailAddress ($emailaddress)
Get-Recipient -ResultSize unlimited | where {$_.emailaddresses -match "$emailaddress"}

See how easy that was?
First you tell powershell that you want to configure a function, then the command you want to associate the function with. Within the ( ) you define what parameters the function will need. Then there’s only a { to start defining what the function will do and a } to end the function.
Now all you have to do in order to find out who or what has a given email address is:


That will tell you what object has the email address and what kind of object it is (UserMailbox, PublicFolder etc.)
