Using Office 365 to Protect Your Email

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

o365-logo1Yep, another PowerShell themed post.

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.

Office 365 Email Password Reminder

powershell2xa4Regular readers will no doubt be aware of the script i wrote about two years ago to alert a user their password was about to expire. If not, just what exactly have you been doing with your time?

In any case, several people have asked me if it can be made to work with Office 365. Using 365 as the email relay to send the messages, was one thing, querying 365 for a users password expiry, was something else. Something which at the time i believe could not be done.

Given they constantly release new features and tweaks, i revisited it this week and found that actually it can now be done, with a few tweaks to the original script.

Quick Fix: Uninstall Symantec Endpoint Protection Remotely

powershell2xa4Finally moving my last client from Symantec SEPM to Trend Micros WFBS Hosted platform. It was a small SEPM deployment, only 7 clients and a server but i was surprised to be reminded that SEPM has no ‘uninstall’ tool from their console. So much for centralised management.

I did a lot of searching around for a reliable solution, most of which came back to using MSIEXEC from a command line.

There are various ways of course to execute a command on a remote machine, you can use PSTools’, PSExec for example, but i prefer to use PowerShell where i can. Read more of this post
