Hi All,

I wanted to get the exported.CSV list of the figure of mailboxes resides on-premise and Office 365 environments in each own.CSV

Here's what I've come up with, but not working:

Code: Select all

Try {
    $UserCredential = Get-Credential
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
    Import-PSSession $Session -Prefix O365 # Prefix to differentiate O365 cmdlets
    
    # Office 365 Mailbox list export
    $MailboxList = @()
    $MailboxList += Get-O365Mailbox -ResultSize Unlimited -RecipientTypeDetails UserMailbox, SharedMailbox | 
                        Get-O365MailboxStatistics | 
                        Sort-Object lastlogontime -Descending | 
                        Select-Object DisplayName, LastLogonTime | 
                        Export-Csv -Path C:\TEMP\Office365-Mailboxes.CSV

    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDMAIL01-VM/PowerShell/ -Authentication Kerberos
    Import-PSSession $Session -AllowClobber

    # Exchange Server 2013 OnPremise Mailbox list export, The last active mailbox login in the past 30 days determine if it is active mailbox or not
    $MailboxList = @()
    $MailboxList += Get-Mailbox -ResultSize Unlimited –RecipientTypeDetails UserMailbox, SharedMailbox;
    $MailboxList | Where-Object {(Get-MailboxStatistics $_.Identity).LastLogonTime -gt (Get-Date).AddDays(-30)} | 
                    Sort-Object -Property @{e = {( Get-MailboxStatistics $_.Identity).LastLogonTime}} -Descending | 
                    Select-Object DisplayName, @{n = "LastLogonTime"; e = {(Get-MailboxStatistics $_.Identity).LastLogonTime}} | 
                    Export-Csv -Path C:\TEMP\OnPremise-Mailboxes.CSV -NoTypeInformation
}
Catch {
    Throw
}
Finally {
    If ($Session) {
        Remove-PSSession -Session $Session
    }
}
This is the error message:
WARNING: The names of some imported commands from the module 'tmp_3rgd0wvj.ptf' include unapproved verbs that might make them less discoverable. To find the commands with unapproved verbs, run the Import-Module command again with the Verbose parameter. For a list of approved verbs, type Get-Verb.

+ ... ypeDetails UserMailbox, SharedMailbox | Get-MailboxStatistics | Sort- ... + ~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Get-MailboxStatistics:String) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : CommandNotFoundException
Any help would be greatly appreciated.

Thanks,

That can be ignored. It is just a warning and depends, in part, on other modules you may have loaded. It can aslo happen if you are running on an older version of WMF. If on-premise Exchange then it may be an older or unpatched version of Exchange.

You will have to do some local troubleshooting. Some older modules for Exchange are no compatible with O365 Exchange.

You also didn't post which import command caused this error.

When I execute this piece of codes in my PowerShell ISE on the laptop, it works and I can get the .CSV file:

Code: Select all

    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDMAIL01-VM/PowerShell/ -Authentication Kerberos
    Import-PSSession $Session -AllowClobber

    # Exchange Server 2013 OnPremise Mailbox list export, The last active mailbox login in the past 30 days determine if it is active mailbox or not
    $MailboxList = @()
    $MailboxList += Get-Mailbox -ResultSize Unlimited –RecipientTypeDetails UserMailbox, SharedMailbox;
    $MailboxList | Where-Object {(Get-MailboxStatistics $_.Identity).LastLogonTime -gt (Get-Date).AddDays(-30)} | 
                    Sort-Object -Property @{e = {( Get-MailboxStatistics $_.Identity).LastLogonTime}} -Descending | 
                    Select-Object DisplayName, @{n = "LastLogonTime"; e = {(Get-MailboxStatistics $_.Identity).LastLogonTime}} | 
                    Export-Csv -Path C:\TEMP\OnPremise-Mailboxes.CSV -NoTypeInformation
Note, for the Office 365 command, I have modified the Get-O365MailboxStatistics.

Code: Select all

    $UserCredential = Get-Credential
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
    Import-PSSession $Session -Prefix O365 # Prefix to differentiate O365 cmdlets
    
    # Office 365 Mailbox list export
    $MailboxList = @()
    $MailboxList += Get-O365Mailbox -ResultSize Unlimited -RecipientTypeDetails UserMailbox, SharedMailbox | 
                        Get-O365MailboxStatistics | 
                        Sort-Object lastlogontime -Descending | 
                        Select-Object DisplayName, LastLogonTime | 
                        Export-Csv -Path C:\TEMP\Office365-Mailboxes.CSV
The Office365-Mailboxes.CSV is produced successfully.

However, when I combine it with the other piece of code for Office 365, it does not working?

Connect to both services first but in the reverse order.

Great. I ran across that about two years ago with another module and the O365 module. Not quite sure why but I suspect upgrading your Exchange might fix it.
