If you have Conditional Access configured and active within your Azure AD environment, there might be some scenario’s where users are not able to sign-in. If you want to troubleshoot these sign-in failures as an administrator you normally turn to the Azure AD sign-in logging and work from there to determine the cause of these failures.

The sign-in logs can be overwhelming though, and you might want to have a more detailed view of the exact scenario that the user is executing so that you can filter the sign-in logging to the specific part where things go wrong.

Well there is a way to accomplish that, by instructing your users to Enable flagging when they hit the error caused by Conditional Access. Here is how it works

When a user cannot access a resource they will probably be presented with a screen like the one below

You cannot access this right now

From that screen the user can select “more details” which will bring up a screen like the one below

Troubleshooting details

This screen already has some very specific information like the Request and Correlation ID which you can use in a filter, but both ID’s are GUIDs which is not very friendly to ask your end users to supply.

We can ask user to “Enable flagging” and which will flag each sign-in event, so that we can filter on them later. Once enabled, each sign-in log will be flagged for 20 minutes. So after users enable this option, you need to ask them to reproduce the issue.

Flagging enabled

Within Azure AD sign-in logging you can create a filter using the “Flagged for review” field

Flagged for review filter option

Once enabled, only the sign-ins where the user enabled flagging will appear in the list of sign-in logs giving you a better filtering option where you can concentrate on the specific issue that the user is experiencing.

Flagged for review enabled in the sign-in log

Flag sign-in errors for review is a very useful feature if you are troubleshooting Azure AD sign-in errors. You have to instruct your users to use it in case of an issue and they need to reproduce the issue for the sign-ins to appear. It can be handy though to filter on the specific scenario instead of going through all the sign-ins of that user instead.
