Office 365 Groups Expiration Review

This is a quick review of the new groups expiration feature in Office 365.

Pros: Very simple to configure – set a group expiration of 180, 365, or Custom.

Then enter an email address of someone to notify if a group does not have an owner.

Those two settings make perfect sense.

The third setting is why I am writing this blog post. The setting ‘Enable expiration for these Office 365 groups” [All] [Selected] or [None]

Let’s dissect this a bit…

ALL probably makes sense …

None might make sense…

 

But I’m having a hard time understanding when I would select certain groups for expiration. You see, by the very nature these Groups are very dynamic usually – by default, any user can create a group. So if today I pick a set of 15 groups that I want to expire, then tomorrow there could be 30 more created that will not expire. So then, I would have to continuously come back here and update that list if there were some groups that I did not want to have deleted. So my choice would then have to be revert to the None setting.

What’s really needed is an exclusion list, ex: Expire all groups EXCEPT for these 5 that I really really care about. All the others, let the owners decide if they want to keep them, but these 5, I keep important stuff in there, and I don’t want to sweat it about missing an email and potentially losing all that information.

So Microsoft, I hope you are listening, please add an Exclusion button. I posted this idea to the UserVoice site here if you want to vote on it!

How to block legacy authentication in Azure AD Premium Conditional Access

Azure AD Premium’s Conditional Access feature requires Modern Authentication to function properly. This has led some to believe that legacy clients (ex: Outlook 2010 and older, or Activesync) can bypass Conditional Access Policies.

Based on my testing, this is only half true, as it depends upon the policy that you select. If you select a ‘Grant’ policy then the legacy clients will not be able to bypass your conditional access policy. However, if you select a Block policy, then the legacy clients will bypass it and connect to the service that you want to block.

So the most conservative thing to do is to use a Grant Policy, not a Block policy.
