May 15, 2019 by 5 Comments

Just a quick post, hit this today with a USB pen drive i keep some deployment tools on. If you are trying to install Office 365 desktop software and you see this message:

Office 365 Product Install

Don’t waste any time trying to find any remnance of a previous Office installation, chances are it is not there!

Download the latest version of the Office Deployment Tool, and while you;re at it head over to the Office Customisation Tool for help with those XML configuration files.

Office 365 Password Policy returns Empty Values in PowerShell

July 5, 2018 by 5 Comments

o365-logo1Regular readers will be aware of a script I wrote some time ago to remind people to change their password, sending them an email when it was due to be changed. I wanted to extend this up to Office 365 but at the time, when I checked it out the relevant data was not exposed by using the Get-MSOLPasswordPolicy cmdlet. Or so I thought.

Whilst chatting with co-conspirator Tim Barrett yesterday he sent me a link to Spice Works where someone named bbeckers had indeed published a modified version of my original script that was talking to Office 365, and, to my surprise was dated back in 2016.

Of course I wanted to try it out, but on my production tenant, the information returned from Get-MSOLPasswordPolicy was an error saying ‘You do not have permission to call this cmdlet’

Quick Fix: Enable DKIM for Office 365

July 26, 2017 by 2 Comments

DKIMIf you have been following some of my recent posts you’ll know i have been talking about Office 365 and Exchange Online and how you can tweak the settings to better secure your mail.

One of the steps for that is to setup DKIM. For Office 365 this requires two CNAME records to be published in your public DNS.

The problem i was having when setting up a new client, was knowing what the CNAME should be set to.

Spear Phishing: What Can you do?

April 28, 2017 by 5 Comments

I have seen a sharp rise in the number of spear phishing attempts my clients are subjected to. I’m sure this trend will continue. Of course our best line of defence when protecting our clients is user education. We can of course try and make things easier for them.

Our most recent example was quite lacklustre by comparison, they hadn’t even bothered to try and find a similar address, just some random Comcast account and setting the ‘From’ name to that of the Executive they were trying to impersonate.

I decided that to counter this we can tag the subject of any such email and then also generate an incident response within Office 365.

Using Office 365 to Protect Your Email

March 28, 2017 by 3 Comments

exchange-2014No doubt everyone reading this is familiar with spoofed email. Where an attacker crafts a message to appear as though it comes from a legitimate sender, in the hopes the recipient will reveal personal information or part with their hard earned cash.

With the rise in so called ‘spear phishing’, being able to effectively block spoofed email is no longer just desireable, it is critical.

Also bear in mind that whilst technologies like Sender ID and DKIM exist, they require both parties of an email to be using them for them to be effective.

You may think any domain you have moved to Office 365 recently is automatically protected by Exchange Online Protection however, like previous versions of Exchange, SenderID checking is disabled by default, as are advanced spam filtering and malware protection. Read more of this post

Manage Multiple Office 365 Tenants from PowerShell

July 28, 2016 by 14 Comments

o365-logo1Yep, another PowerShell themed post.

This is something I cobbled together a few years back, never thought it was worth sharing, but sitting here this evening with nothing much to do decided to write it up.

At it’s core it is not much more than a method of automating entering credentials to your various Office 365 ‘Clients’. I say ‘’clients” because I do not know if that is the correct terminology. If you are the Partner of Record or even if you are supporting more than one tenant on 365 this may be useful to you.
