Hi There,

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.

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

    https://support.microsoft.com/en-us/topic/autodiscover-event-id-1-after-installing-exchange-server-2019-cu3-or-exchange-server-2016-cu14-93850e62-4cf4-8a76-5fd4-c8ce6f032015

    I have this problem even with the latest CU.

    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.
