Quota if Mailbox Size script for Exchange 2010,2013

If your playing around with different Mailbox quota values you might want to see what the usage of those quotas would be before you apply them to a Mailbox. This is a very simple Mailbox Size script for Remote Powershell to show you this with a funky console graph output (and a CSV report) eg


So what the script does is the normal Get-Mailbox | Get-MailboxStatistics to get the TotalSize of the Mailbox in MB and compares that against a QuotaIf Value you feed into script in the above example that was 2000 MB. It then works out the current percentage used and the produces an Alt-ASCII graph and the above table.

When you run this script you need to feed in the QuotaIf value eg

.\quotaIf.ps1 2000

I've put a download of this script here and code itself looks like

  1. $QuotaIfVal = $args[0]  
  2. $Script:rptCollection = @()  
  3. get-mailbox -ResultSize unlimited| Get-MailboxStatistics | foreach-object{  
  4.     $rptObj = "" | Select MailboxName,TotalSize,QuotaIfPercent,PercentGraph  
  5.     $rptObj.MailboxName = $_.DisplayName  
  6.     [Int64]$rptObj.TotalSize = ($_.TotalItemSize.ToString() |%{($_.Substring($_.indexof("(")+1,$_.indexof("b")-$_.indexof("(")-2)) -replace(",","")})/1MB  
  7.   
  8.     $rptObj.QuotaIfPercent = 0    
  9.     if($rptObj.TotalSize -gt 0){  
  10.         $rptObj.QuotaIfPercent = [Math]::round((($rptObj.TotalSize/$QuotaIfVal) * 100))   
  11.     }  
  12.     $PercentGraph = ""  
  13.     for($intval=0;$intval -lt 100;$intval+=4){  
  14.         if($rptObj.QuotaIfPercent -gt $intval){  
  15.             $PercentGraph += "▓"  
  16.         }  
  17.         else{         
  18.             $PercentGraph += "░"  
  19.         }  
  20.     }  
  21.     $rptObj.PercentGraph = $PercentGraph   
  22.     $rptObj | fl  
  23.     $Script:rptCollection +=$rptObj   
  24. }  
  25. $Script:rptCollection  
  26. $Script:rptCollection | Export-Csv -NoTypeInformation -Path c:\temp\QuotaIfReport.csv -Encoding UTF8

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

EWS-FAI Module for browsing and updating Exchange Folder Associated Items from PowerShell

Folder Associated Items are hidden Items in Exchange Mailbox folders that are commonly used to hold configuration settings for various Mailbox Clients and services that use Mailboxes. Some common examples of FAI's are Categories,OWA Signatures and WorkHours there is some more detailed documentation in the https://msdn.microsoft.com/en-us/library/cc463899(v=exchg.80).aspx protocol document. In EWS these configuration items can be accessed via the UserConfiguration operation https://msdn.microsoft.com/en-us/library/office/dd899439(v=exchg.150).aspx which will give you access to either the RoamingDictionary, XMLStream or BinaryStream data properties that holds the configuration depending on what type of FAI data is being stored. I've written a number of scripts over the years that target particular FAI's (eg this one that reads the workhours  http://gsexdev.blogspot.com.au/2015/11/finding-timezone-being-used-in-mailbox.html is a good example ) but I didn't have a gene...

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.
