Firstly, apologies that this reply is nearly two years after the question, but I also wanted to check email using Powershell and found this question. Hopefully my code will serve as a reference/starting point for someone else looking to mine outlook from Powershell. I plan to enhance this myself to make it more usable.
I'm pretty new to Powershell, so my scripts are predominantly Frankenstein-ed from various articles, blog posts and StackOverflow Q&A's of course, the script below being no exception!
Following on from Chris' response, I did a little further digging around the internet and cobbled together a few snippets of Powershell to allow me to display a few key pieces of information from emails.
It's sadly lacking in any 'proper' style and I'm sure that any Powershell gurus will cringe at this. But what this code does do is
- show how to use EWS & Powershell to read emails
- address George's last question re: the body being blank - the
FindItems method doesn't return the full mail item, you have to make another round-trip to get the extra information you need.
- remove the requirement for you to use username/password/domain by using your current credentials
- remove the requirement to 'install' EWS, simply extract the MSI and reference the dll
To use...
Download the EWS from here then extract somewhere, e.g.
msiexec /a C:PathToDownloadsEwsManagedApi.msi /qb TARGETDIR=C:ProgsEwsManagedApi
then call this script using dot-source, e.g.
. C:PathToScriptOutlook_ReadInbox.ps1
which allows you to reference the objects/variables from the script after it has executed.
The code has a limited comments throughout, as well as a few links at the end, which I referenced when cobbling the script together.
Here's my alpha draft of code to read in the first 5 emails, display whether read/unread and show the first 100 characters of the email body on one line with white-space removed.
