Azure information protection custom policies not working
Hello, I'm playing around with an Enterprise Mobility + E3 license and security and I was following the next tutorial/document from Microsoft: https://docs.microsoft.com/en-gb/information-protection...
In addition to checking the firewall isn't blocking IP addresses and URLs, check it's not terminating your TLS connection, which breaks certificate pinning. I've added a tip how to check for this client-side, if you don't manage the firewall yourself. See https://docs.microsoft.com/en-us/information-protection/get-started/requirements#firewalls-and-network-infrastructure
One thing that worked for me after getting this error message was to go to a random Word document saved anywhere on your computer. In File Explorer, right-click the Word document and click Classify and protect to open the AIP Client.
Next, select one of your custom labels, it shouldn't matter which one and click apply. This forces the custom label in a way that you can't do in Word. After that I was able to assign custom labels within Word after that with no issues. Hope that helps.
