Reporting on the Top 10 largest emails in each users mailbox in Exchange

Someone asked for a script last week to show the top 5 largest emails by size in each user’s mailbox being a Letterman fan (yep we get it here in Aus just no all the jokes) I tough I’d post it as a Top 10 script. You can expand on this concept to really look at the Top 10 of anything in your user's mailbox's (drum roll at meeting not included). The script is basically the mailbox content age script I posted a while ago modified to instead create a disconnected record-set of the largest 10 items in each folder in a mailbox and then basically sort this list at the end of the mailbox scan and write the top 10 largest items for each user to a separate htm file in the reports directory. To limit the query to only return the top 10 largest items in each folder the query uses the order by SQL verb to sort the result by the item size and to limit the number of results returned the range header is used in WebDAV eg

req.setRequestHeader "Range", "rows=0-9"

This means only the first 10 rows of the result is returned which cuts down the processing of the script greatly and means the execution time and load on the server is greatly reduced. The script uses the admin virtual root so it will run with delegated Exchange Admin Rights. The script requires 1 command-line parameter which in the servername of the server you wish to run it against eg something like

Cscript shotop10.vbs servername

I’ve put a downloadable copy of the script here the script itself looks like.

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

Writing a simple scripted process to download attachmentts in Exchange 2007/ 2010 using the EWS Managed API

Every complicated thing in life is made up of smaller simpler building blocks, when it comes to writing a script (or any code really) the more of these little building blocks you have to figure out the more the process of solving a problem can become bewildering. The Internet generally provides you with lots of half eaten sandwiches of information something someone else has taken a bite out but a lot of the time half done, and as with any code its usefulness declines over time as new and better API's and methods are derived. In this post I'm going to go through a simple scripted process that hopefully covers a few more of these smaller building blocks that you might face when asked to come up with a simple costless solution to perform an automated business function with a script. So the process im going to look at is one that comes up a lot and that is you have an Email that comes into to certain mailbox every day with a certain subject in my case "Daily Export" this

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/filena
