Outlook 2016 Exchange 2010 autodiscover, multiple domains
My first time asking EE question
I have an Exchange 2010 server. External clients have been connecting to my server without issues via proxy https until they decided to upgrade to Outlook 2016. My clients domains are different than my own. I can connect myself externally, so I know our autodiscover is probably setup correctly. But my clients cannot connect
I put the following in Outlook 2016, works fine:
pli@mydomain.ca
my password
This does not work:
pli@myclient.ca
their password
https://mail.mydomain.ca/autodiscover/autodiscover.xml is accessible and returns the 600error message
I tried CNAME my client's on cpanel:
autodiscover.myclient.ca -> mail.mydomain.ca
I tried the XML regedit hard code with autodiscover.xml
On a side note, I've tried to do linked mailboxes because I read somewhere this can also solve my problem, but when I get to Trusted Forests or domains, it is blank even though I selected the database in the previous menu. Not sure where to go from here...

I get all errors for my clients domain autodiscover. Attaching photo, not sure how I can point their autodiscover to my domain autodiscover. I've tried CNAME as previously mentioned.
More and more clients get 2016 by default when installing Office365. One client insists on using 2016, so downgrading is my last resort.

Btw, is there an option to downgrade to 2013 in Office365? Would help to get my clients going instead of using OWA
Yes, it's not easy to find but under the 'install" area, look down below and it says "other installs" (which MS hates saying "downgrades" LOL)
Then you can select 32 or 64 bit. I do 32 usually.

Thanks, I will temporarily try this to quell the storm. Still hope to get a server side solution to 2016 autodiscover.
We all can hope they add back the manual settings :) I wish, dream and pray daily lol!

Next best alternative to MS BS
what error do you get when you run Outlook Autodiscover and/or Outlook Connectivity on https://testconnectivity.microsoft.com/ ,for pli@myclient.ca ?
