    I've hit a mental block here...I'm sure this should work, but it's not. I've created a variable and used get-aduser to populate it, straight forward.

    PS Child:\> [Array]$ExistingUserDetails = Get-AdUser $username -Properties GivenName,SurName,EmailAddress,Office,Title
    PS Child:\> $existinguserdetails

    DistinguishedName : CN=blah,OU=blah,OU=blah,OU=blah,DC=blah,DC=blah,DC=blah
    EmailAddress :
    Enabled : True
    GivenName : John
    Name : John Smith
    ObjectClass : user
    ObjectGUID : xxxxxxxx
    Office : OfficeLocation
    SamAccountName : JSmith
    SID : S-1-1-1-11111111-1111111-111111111-11111
    Surname : Smith
    Title : Squire
    UserPrincipalName : JSmith@blah.blah.blah

    However, when trying to call particular pieces of information, such as givenname, I get nothing:

    PS Child:\> $existinguserdetails.surname
    PS Child:\> $existinguserdetails.givenname

    I thought i could query the array like this, and it should jsut return "John". What I am getting inside my script when I query $existinguserdetails, is just the first line returned, the "DistinguishedName" value only.
    Literally if I do a "write-host $existinguserdetails", I get one line only. Even though when I manually run the commands it returns the 13 lines.

    So... that's because you created an array. You have to tell it which array element you want. Since there's likely only one, $existinguserdetails[0].surname should work.

    One doesn't "query" an array. You just access data in it. Querying implies it's going to search something for you, and it ain't.

    Curious: Why are you casting it as an array? Get-ADUser will return a single object if there's only one match, and return a collection (array) if there's more than one match. Do you need to force it into an array?
