Mail-Enabled Security Groups in Office 365 are an important security measure, as they enable administrators to control access to resources within an Office 365 tenant.

With properly configured mail-enabled security groups, administrators can restrict access to sensitive data and protect the environment against malicious activity.

Sometimes, a mail-enabled security group might not work the way you want it to. However, there’s no need to worry since our article will be talking about these issues and what you can do to resolve them.

What Causes Issues With Mail-Enabled Security Groups

The good thing about security groups is that they don’t encounter many problems, and the issues that come up are pretty straightforward to solve. Here are some things that might be the cause of your mail-enabled security group not working correctly:

Problem #1: Incorrect Configuration

If a security group is configured incorrectly, you’re likely to encounter issues that may include not being able to send out emails or not having access to the right permissions in Office 365.

That is why it is essential to make sure you’ve ticked all the right settings, and if you haven’t, there’s no need to worry. You can either create a new group or change the settings of the current one:

Problem #2: Users Aren’t Able To Access Files

If users cannot access the resources, they should be able to in a security group, or if they are receiving some sort of error message when they try to get a hold of these files, then the issue is likely to be related to the membership of the security group.

This means that they’re probably not part of that mail group and hence cannot access the directories.

Method #2: Add Users To A Specific Security Group Using Administrator

The solution to the second problem is pretty simple, which is to ask the administrator to add users to a specific security group if they’re unable to access their resources.

However, only the owner of the group can make these changes, so you’ll have to seek one if you want to follow this method. On the other hand, if you’re the owner of the group, here’s how you can do it:

  1. In the EAC, go to the member’s section
  2. Then, click on “View all and manage members” to either add or remove members
  3. Add the members who aren’t able to access the files and click save.


All in all, Mail-Enabled Security Groups are a pretty essential feature in Office 365 that allows the right users to have access to the right resources. If you’re facing issues with these groups, we hope our short troubleshooting guide will help you solve the problem at hand.
