Microsoft Remote Desktop Keychain access

I use Microsoft Remote Desktop and have passwords saved for different remote desktop connections. Since some time back I get the error: > We couldn't retreieve your password from your keychain, please enter your password again. I've reset the Keychain inside Keychain Access Management: I've also looked for cached files in ~/Library/Caches but didn't find any for Microsoft Remote Desktop. I get the same problem when running Microsoft Remote Desktop Beta.
