Sometimes while configuring the AIP you may encounter several of issues, two of the most well know are :

Let’s start troubleshooting

Below you can see a few solutions that you need to try in order to fix the problem.

Solution 01: Uninstall and reinstall the AIP client

To completely remove the Azure Information Protection client you need to follow the steps below:

Step 2. Open the Apps & features and select to Uninstall the Azure Information Protection Client

Step 3. Backup Windows Registry and then delete the key {HKEY_CURRENT_USER\Software\Microsoft\MSIP}

Step 4. Delete the folder C:\Users\{my user name}\AppData\Local\Microsoft\MSIP

Step 5. Remove Windows credentials from windows credential manager.

Step 7. Download and Install the Azure Information Protection client. You can do it by following the User Guide.

 

Solution 02 : Check for any security group configured to AIP policy

If the first solution didn’t work for your issue, then you can try the second. In this case, you need to check if there is any security group configured to AIP policy, and this could be the reason that you are not able to apply labels to emails and documents.

You can find the security group by running the following PowerShell commands.

# Install aipservice  module

Install-Module -name aipservice

# Connect to AIP service

connect-aipservice

# Get AIP Service Status

Get-aipservice

# Check the AIP Policy and Identify the security group

get-Aipserviceonboardingcontrolpolicy

get-msolgroup -objectid {id}
