Autodiscover isnt working when I try and connect my accounts to Outlook on computer or iOS. It just says unable to signin. On Microsoft remote connectivity analyzer these are the results:

Any suggestions would be very much appreciated.

Thank you.

Answer 1

I have encountered the problem that Autodiscover is not configurable in EMS and you have to do it in PowerShell.

I have this problem even with the latest CU.

Answer 2

Hi @Aaron Fraser ，
If you have published your environment to the public network, please have a check if there is an Autodiscover record in DNS that points to the Exchange IP address.
If not ,please add a new ”A” record and see if it works.
