More fun with combining mutliple Powershell cmdlets to produce reports

Over the years one of the most popular and useful scripts i've written and gotten feedback and questions on is the various mailbox size scripts i've posted here and on Outlookexchange. The fact that this functionality has been pulled from the GUI in Exchange 2007 doesn't appear to have been a very popular decision amongst sysadmins i guess the majority of which don't want to look at a line of code or script. While this blog/post isn't probably for those people If you are really ruing the loss of Mailbox size information out of the GUI don't think about what you have lost but whats been gained through the flexibility of Powershell and the Exchange Cmdlets. GUI's are great for displaying simple information but anyone who's been working in IT for any length of time knows that requests are rarely simple and not always logical when dealing with management. Trying to make information you export from a GUI display the way you want can be time consuming and tedious and really tie up time that could be better spent elsewhere. While the unavoidable reality may be yes you need learn how to script and really these day when i say that I'm not talking about VBS which like the Model T Ford has had its day. The main point is you see that thing in fount of you with the flashing cursor and the keyboard designed to slow you down its main purpose in life is to save you time and make your life easier well isn't it about time it started to ? .

This is a question i recieved via email this week and its typical of the kind of thing im talking about.

How do i export the list for Exchange Users from Exchange Server 2007 SP1 by using a cmdlet:


I want something like the following table

Example:

Department , Alias , DefaultQuota ,OverQuota ,TotalitemSize, LastAccessTime

Now it would be nice if there was a simple Oneliner powershell cmdlet that could return this information but there isn't. What you need to do is combine a number of different cmdlet's to get the information you want. And this is really where the Power in Powershell comes in because it allows you to easily integrate the result of different operations. So to get this information we need to combine get-mailbox, get-mailboxstatitics and to get information about what department the users is in straight ADSI is the best way to go. To be able to use the Export cmdlets that come with Powerhell its best to store the result of your combination in a custom object and then when it comes time to produce the report you can the use something like export-csv or converttohtml . So the following script is one method of solving the above question it reuses a cut down version of the mailbox size gui script that been tweaked to show the required information and produces a CSV file at the end. The script has one variable that is hardcoded which is the name of the server you want to run the script against which you will need to change. I've put a download of this script here the script it self looks like

$snServerName = "servername"
$fname = "c:\mbreport.csv"
$usrquotas = @{ }
$mstoresquotas = @{ }
$mbcombCollection = @()

get-mailboxdatabase -server $snServerName | ForEach-Object{
if ($_.ProhibitSendReceiveQuota.IsUnlimited -ne $true){
$mstoresquotas.add($_.identity,$_.ProhibitSendReceiveQuota)
}

}

$usrquotas = @{ }
Get-Mailbox -server $snServerName -ResultSize Unlimited | foreach-object{
if($_.ProhibitSendReceiveQuota.IsUnlimited -ne $true){
$usrquotas.add($_.ExchangeGuid,$_.ProhibitSendReceiveQuota)
}
}
$quQuotaval = 0
get-mailboxstatistics -Server $snServerName | Where {$_.DisconnectDate -eq $null} | ForEach-Object{
$quQuota = "0"
if ($usrquotas.ContainsKey($_.MailboxGUID)){
if ($usrquotas[$_.MailboxGUID].Value -ne $null){
$quQuotaval = $usrquotas[$_.MailboxGUID].Value.ToMB()
$quQuota = "{0:P0}" -f ($_.TotalItemSize.Value.ToMB()/$usrquotas[$_.MailboxGUID].Value.ToMB())}
}
else{
if ($mstoresquotas.ContainsKey($_.database)){
if ($mstoresquotas[$_.database].Value -ne $null){
$quQuotaval = $mstoresquotas[$_.database].Value.ToMB()
$quQuota = "{0:P0}" -f ($_.TotalItemSize.Value.ToMB()/$mstoresquotas[$_.database].Value.ToMB())}}
}
$icount = 0
$tisize = 0
$disize = 0
if ($_.DisplayName -ne $null){$dname = $_.DisplayName}
if ($_.ItemCount -ne $null){$icount = $_.ItemCount}
if ($_.TotalItemSize.Value.ToMB() -ne $null){$tisize = $_.TotalItemSize.Value.ToMB()}
if ($_.TotalDeletedItemSize.Value.ToMB() -ne $null){$disize = $_.TotalDeletedItemSize.Value.ToMB()}
$mbcomb = "" | select DisplayName,QuotaSize,TotalItemSize,Department,LastLogonTime
$mbcomb.DisplayName = $dname
$mbcomb.QuotaSize = $quQuotaval
$mbcomb.TotalItemSize = $tisize
$usrString = 'LDAP://' + $_.identity
$usr = [ADSI]$usrString
$mbcomb.Department = $usr.Department
$mbcomb.LastLogonTime = $_.LastLogonTime

$mbcombCollection += $mbcomb
}

$mbcombCollection | export-csv -noTypeInformation $fname

Export calendar Items to a CSV file using Microsoft Graph and Powershell

For the last couple of years the most constantly popular post by number of views on this blog has been  Export calendar Items to a CSV file using EWS and Powershell closely followed by the contact exports scripts. It goes to show this is just a perennial issue that exists around Mail servers, I think the first VBS script I wrote to do this type of thing was late 90's against Exchange 5.5 using cdo 1.2. Now it's 2020 and if your running Office365 you should really be using the Microsoft Graph API to do this. So what I've done is create a PowerShell Module (and I made it a one file script for those that are more comfortable with that format) that's a port of the EWS script above that is so popular. This script uses the ADAL library for Modern Authentication (which if you grab the library from the PowerShell gallery will come down with the module). Most EWS properties map one to one with the Graph and the Graph actually provides better information on recurrences then...

Downloading a shared file from Onedrive for business using Powershell

I thought I'd quickly share this script I came up with to download a file that was shared using One Drive for Business (which is SharePoint under the covers) with Powershell. The following script takes a OneDrive for business URL which would look like https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filename.txt This script is pretty simple it uses the SharePoint CSOM (Client side object Model) which it loads in the first line. It uses the URI object to separate the host and relative URL which the CSOM requires and also the SharePointOnlineCredentials object to handle the Office365 SharePoint online authentication. The following script is a function that take the OneDrive URL, Credentials for Office365 and path you want to download the file to and downloads the file. eg to run the script you would use something like ./spdownload.ps1 ' https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filen...

Sending a MimeMessage via the Microsoft Graph using the Graph SDK, MimeKit and MSAL

One of the new features added to the Microsoft Graph recently was the ability to create and send Mime Messages (you have been able to get Message as Mime for a while). This is useful in a number of different scenarios especially when trying to create a Message with inline Images which has historically been hard to do with both the Graph and EWS (if you don't use MIME). It also opens up using SMIME for encryption and a more easy migration path for sending using SMTP in some apps. MimeKit is a great open source library for parsing and creating MIME messages so it offers a really easy solution for tackling this issue. The current documentation on Send message via MIME lacks any real sample so I've put together a quick console app that use MSAL, MIME kit and the Graph SDK to send a Message via MIME. As the current Graph SDK also doesn't support sending via MIME either there is a workaround for this in the future my guess is this will be supported.
