GDPR which stands for General Data Protection Regulation is one of those things that surfaces in the IT world (y2k would be another) that seems like a godsend to the lawyers and anybody doing project management.  Endless paperwork, meetings, manual writing and training that seems to achieve little but cost a ton. One of the problems with GDPR is the very broad brush it paints with about what is considered private data and what constitutes compliance. What I'm going to cover in this post is what you can do if your on the receiving end of a GDPR data request around Contacts that are stored in an Exchange Mailbox and how scripting can help you out. I'm not going to talk about any of the legalities around GDPR because its a bit of minefield but look more at it from the data prospective. Mailbox Contacts From a strictly data view the majority of properties that make up an Outlook Contact record is private data. Eg a Persons Name, PhoneNumber, Email Address, Address information e

Its been quite a busy week in Email security the pass 7 days with 2 new vulnerabilities released in the last week first BaseStriker  https://www.avanan.com/resources/basestriker-vulnerability-office-365 and now EFail https://searchsecurity.techtarget.com/news/252441096/Efail-flaws-highlight-risky-implementations-of-PGP-and-S-MIME . While its still too early to gauge the implications of both of these flaws what they both have in common is using the HTML body of a message and underlying html markup tags to make these exploits work. With baseStriker its the use of the Base Href tag in a HTML document and with EFail using an Img Src tag to send decrypted email contents to an external server (this is an over simplification). In this post I'm going to look at how you can parse the HTML Links, Image SRC tags from messages that are sitting in a Mailbox (so post any Transport pipeline filtering) and provide a level or reporting on these. Or basically because we are going to be using the

This is part 2 of my Junk Email reporting series of posts for Part 1 which covers using Message Tracking please see . In this post I am going to look at using the Mailbox API's EWS and REST to actually read the contents of the Junk Email folder in Exchange and from there we can report on the various aspects of the Antispam information that is available in the Message Headers. Firstly if you are just looking for something to do single message analysis then I would check out Stephen Griffin's  Message Header Analyser Addin for Outlook   https://appsource.microsoft.com/en-us/product/office/WA104005406 this is a brilliant little tool for that. In this post I will focus on doing it in bulk using PowerShell and building some reports to allow you to see what's happening. Mailbox Access A big consideration if your going to be accessing Mailbox data is security, one of the benefits of using the REST api over EWS is that you can be very granular about the access that you give
