An Ode to EOP

This is typically a slow week for people, so what better time than to post something fun about Exchange Online Protection! Back in May I presented a session on EOP at TechEd North America 2014 which took place in Houston. To be a little different, I wrote a poem about EOP which I read to…


Top Ten Posts of 2014

I only began this blog in June of this year and so it’s hard to believe that it is already six months old! Looking back over the past six months I have had a blast writing and sharing articles with the community and have received a lot of positive feedback. I have a long list of…


Message Trace, the PowerShell Way

From my experience, a very small number of people actually choose PowerShell over the GUI (Graphical User Interface, ie. The Office 365 Portal). But once you get a grasp of PowerShell and write some scripts, you’ll see the light and going back to your old ways will be very hard. PowerShell has two big advantages….


Exchange Server December Updates

Update, Dec 15/14: Exchange Server 2010 SP3 Update Rollup 8 v2 has been posted While I mainly target Exchange Online Protection with this blog, a lot of customers use EOP to protect on-premises Exchange environments. As such…


Remote Desktop Connection Manager updated to v2.7

Remote Desktop Connection Manager, or RDC Man, is a wonderful piece of software that I’ve been using for the past eight years. RDC Man is one of those applications, like Outlook, that I open almost every single day and although not directly applicable to EOP or Exchange Online, it is applicable to most operations type…


An Early Gift, EOP Bulk Mail Detection – The Easy Way

This past summer we added new bulk detection capabilities to Exchange Online Protection. At the time, if you wanted to take advantage of these new capabilities you had to add an EOP transport rule to detect the BCL (bulk complain level) that EOP stamped on incoming messages. This new capability worked wonderfully, but the problem…


Easily tell which transport rules a message triggered

Hello fellow traveller, come sit with me by the fire, there is plenty of room. You look to be weak from your travels, I have plenty of rations that I will gladly share with you. I have many stories from my own travels that I would love to share. Wait…, you want to know about…


Transport Rule Limit Increase

In the past the maximum number of transport rules that you could create in Exchange Online (Enterprise, Education, and Government plans) was 100. This limit has recently been increased to 300 (for Enterprise, Education, and Government plans)! For those that were concerned about reaching the 100 rule limit, you now have 200 more rules that can be…


Best Practices for Finding Executable Content

UPDATE (October 14, 2016): We now recommend using the Common Attachment Types Filter to block file types as opposed to using transport rules. Take a look at my updated post, Common Attachment Types Filter, for more information on this new filter.   This article may be common knowledge for some, but it is important to…


P2 Headers Now Respected for End User Safe and Blocked Senders Lists

Exchange Online Protection will now evaluate both the P1 and P2 headers in a message against an end users safe and blocked senders list. I know, I’m super excited too! Previously only the P1 header of a message was compared to these lists. Not only does this make blocking or safe listing within Outlook or…
