Users are getting authentication prompt then Error 401 when using edge with work server
We have tried with a few different users and all have the same repeated prompts for credentials. I have tried all combinations with/without UPN or DOMAIN etc and just get repeated prompt, clicking cancel gives error 401. I have cleared all cache/cookies I have tried inprivate browsing I have tried rebooting my machine I have added to trusted sites (even though its a domain server) This has affected every person we have tried with but only on Edge. Chrome works fine with no authentication prompt. Any help greatly appreciated!
