I get connected to Exchange in the cloud by issuing a series of powershell commands:
$credential = new-object -typename ... -argumentList ...
$session = New-PSSession -configurationName ... -connectionUri ... -credential $credential ...
Import-PSSession $session ...
I can then issue commands to do things I need to do, eg,
get-mailbox | ? {$_.aliast -like "*[.]*"} | select alias
alias
-----
john.public
jane.doe
...
However, the cmdlets for obtaining a PSSession are long, and typing them is error-prone even if I could manage to memorize them correctly. So I saved all the three long command lines verbatim in a function:
function get-365session() {
$credential = new-object -typename ... -argumentList ...
$session = New-PSSession -configurationName ... -connectionUri ... -credential $credential ...
Import-PSSession $session ...
}
But it does not work out as expected:
PS> get-365session
ModuleType Version Name ExportedCommands
---------- ------- ---- -----------------
...
PS> get-mailbox
get-mailbox: The term 'get-mailbox' is not recognized as the name of a cmdlt, function, script file, ....
I thought the session was obtained but was gone with the function's "sub-shell" as soon as the function has completed its run. I therefore tried
PS> . get-365session
But it was to no avail.
Hope there is a way and someone can help me out. Many thanks!
You need to import the session in the current scope using Import-Module
with the -Global
flag.
Your Import-PSSession
line should look like
Import-Module (Import-PSSession $session365 -AllowClobber) -Global
Here is a working example:
function Connect-O365{
$o365cred = Get-Credential username@domain.onmicrosoft.com
$session365 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $o365cred -Authentication Basic -AllowRedirection
Import-Module (Import-PSSession $session365 -AllowClobber) -Global
}
Connect-O365
Reference
Local functions and variables are not available in other sessions. However, you can use the following trick to specify your function as a script block:
Invoke-Command -Session $session -ScriptBlock ${Function:My-FunctionName}
The article I linked to above goes into more detail about more advanced use-cases for this, but as your script doesn't seem to require any parameters. Do note that this requires the use of Invoke-Command
to run the code in the other session, from the session where the function is defined , so I'm not sure how, if you could, get the function body if you have already done Enter-PSSession
and are currently in the remote session.
