Email security in Office 365

Arjan Cornelissen
There are various ways of security in office 365, this time I walk you thru the security possibilities for Email. As we start with the basics, we have the option to use an SPF record to protect us from spam on a very basic level. This is so basic and a requirement when you add the domain to Office 365. As we go deeper into the security of the mail flow we see DKIM and DMARC.

SPS Paris and SPS Belgium

Last two weekends I went to SharePoint Saturday in Paris and Belgium. It is always great to meet other SharePoint and Office 365 consultants, customers and suppliers. SPS Paris The first weekend I went to Paris where I did not read my emails to carefully, so I was at the wrong venue. I was not the only one. It took some extra time to get to the new location. Arrived there I was just in time for the first session; this was a session about the secure score site from Microsoft.

Enabling modern authentication on Office 365

Arjan Cornelissen
The first thing that might come to your mind might be that modern authentication is enabled for Office 365. Well that is partly true. It is enabled for SharePoint online, not for Exchange and Skype for Business if your tenant is created before august 1st 2017. While writing this about 95% of the tenants are older then 1 month so modern authentication is not enabled for Exchange and Skype for Business.

Connect to Exchange Online PowerShell with MFA enabled account

Connecting to Exchange Online was only possible with an account that did not have MFA enabled because it only can handle basic authentication. This is an issue because Microsoft advises us to have accounts that can do administrative tasks to have MFA enabled. Now we must choose between an account that has no MFA and a possible security breach and an account that cannot connect to Exchange Online. To solve this, we had an account that was disabled by default and when we had to do Exchange tasks we enabled it.

This screenshot has selected division and employeeID, but in the complete list of available attributes there are also the ExtensionAttributes.
