Exchange 2007 Mailbox Size Powershell Form Script version 3

Version 4 has now been released that includes mailbox quotas here

I've been promising to update this for a while to fix a few issues and fulfill of few requests . I've switched the FolderSize code from using EWS to query the foldersizes to now use the Get-MailboxFolderStatistics Cmdlet instead. This makes the code a lot more functional and easy to use and doesn't require all that messing around with Impersonation and SSL (I kind of missed the whole Get-MailboxFolderStatistics cmdlet but it was fun building the EWS stuff anyway).

I've also now used DataGrids to display the result which means it is now sortable (Yeah!) you can now sort to your hearts content on any of the displayed columns. The only thing with Datagrid 's because of the threading issue with Powershell i couldn't use the click event so to display the foldersize you need to select the mailbox you want to show and then click the Get Folder Size button.

Another feature I've added is the ability to export both the Mailbox Size Grid and the Folder size grid. There are buttons bellow both the Datagrids that will open a dialogue box to allow you to choose a location to export to and produce a CSV file of the current results in the datagrid.

The last feature I've added is the ability to show just the Disconnected mailboxes so this will allow you to report just the sizes of all the Disconnected Mailboxes on you server. The one thing you cant do with a disconnected mailbox is show the foldersizes.

One last bug fix was to switch to using 64 Bit integers to fix a problem when the folder sizes go over 2 GB. I haven't been able to test this properly yet so please let me know if its still an issue.

The only real requirement now to run this code is that you run it from within the Exchange Management Shell because it uses a couple of the Exchange cmdlets the user running the code needs to have a least Exchange View-Only Administrator role rights.

I've put a download of the new script here the new code looks like


function getMailboxSizes(){

if ($mtTypeDrop.SelectedItem -ne $null){
if ($mtTypeDrop.SelectedItem.ToString() -eq "Disconnected"){
get-mailboxstatistics -Server $snServerNameDrop.SelectedItem.ToString() | Where {$_.DisconnectDate -ne $null} | ForEach-Object{

$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.ToKB() -ne $null){$disize = $_.TotalDeletedItemSize.Value.ToKB()}

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 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 '

Export calendar Items to a CSV file using EWS and Powershell

Somebody asked about this last week and while I have a lot of EWS scripts that do access the Calendar I didn't have a simple example that just exported a list of the Calendar events with relevant information to a CSV file so here it is. I've talked on this one before in this howto  but when you query the calendar folder using EWS you need to use a CalendarView which will expand any recurring appointments in a calendar. There are some limits when you use a calendarview in that you can only return a maximum of 2 years of appointments at a time and paging will limit the max number of items to 1000 per call. So if you have a calendar with a very large number of appointments you need to break your query into small date time blocks. In this example script I'm just grabbing the next 7 days of appointments if you want to query a longer period you need to adjust the following lines (keeping in mind what I just mentioned) #Define Date to Query $StartDate = (Get-Date) $EndDate

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 . 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 Graph is limited to a m
