MacOS managed devices: allow access to "Microsoft Workplace Join Key"
This happens sometimes (for unknown reasons) on Macs managed by InTune, JAMF, etc. To fix it, find the key and allow all apps to access it...
Open the "Keychain Access" utility. Find the certificate. Select "allow all applications to access item". Enter your login password if requested. Re-launch the web browser.
