Office 365 powershell


I am looking to export a list of enabled users in Office365 to csv who haven't sent an email in over 90 days, I started working on a script but keep getting errors, any suggestion?

$UserStats = Get-mailbox -resultsize unlimited | Get-MailboxStatistics | where {$_.LastLogonTime -lt ((get-date).AddDays(-90))} | Get-MsolUser -EnabledFilter EnabledOnly | 
Select userprincipalname,Licenses,lastlogontime > c:\ps\export.txt

Try this and let me know if it works:

$CollectUsers = Get-mailbox -resultsize unlimited -RecipientTypeDetails UserMailbox,SharedMailbox |Get-MailboxStatistics |where {$_.LastLogonTime -lt ((get-date).AddDays(-90))} 
$UserStats = @()

foreach($user in $CollectUsers){
$obj = "" | select userprincipalname,Licenses,LastLogonTime
$x = Get-MsolUser -UserPrincipalName (Get-Mailbox $user.MailboxGuid.Guid).UserPrincipalName | ? {$_.isLicensed -and !($_.BlockCredential)}
$obj.LastLogonTime = $user.LastLogonTime
$obj.userprincipalname = $x.userprincipalname
$obj.Licenses = $x.Licenses
$UserStats += $obj
$UserStats | Out-File c:\ps\export.txt

You are piping 2 differents Cmdlets from 2 different "sources".

O365 contains the "MsolService" conenction that is what you see in the portal of o365 administration.
But the Get-mailbox is only available in the "Exchange Online" Environment.

So that way will never work bud.
How should you go then?
1st Solve the Exchange Online to find out those who haven't logged in into the last 90 days,
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session
$Inactive90=Get-mailbox -resultsize unlimited |select * | Get-MailboxStatistics | where {$_.LastLogonTime -lt ((get-date).AddDays(-90))} | select DisplayName

Open in new window

This way on the var "Inactive90"  (that only brings DisplayName as an important field.

The end result will be like:
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session

$Inactive90= Get-Mailbox -resultsize unlimited | Get-MailboxStatistics  | where {$_.LastLogonTime -lt ((get-date).AddDays(-90))} 
Connect-MsolService -credential $UserCredential 
foreach($user in $Inactive90){
	$search=Get-MsolUser -EnabledFilter EnabledOnly | where{ $_.DisplayName -eq $user.DisplayName} | select userprincipalname,Licenses,lastlogontime

$Result| ConvertTo-Csv -NoTypeInformation file.csv

{ $_.LastLogonTime -lt (get-date).AddDays(-90) } isn't the same as "haven't sent an email in over 90 days". The user might have read emails, and therefor needed to log in.
