We have an on-premises Exchange Server 2019. Everything was working fine until we got an external spam filtering service. We changed our MX records to point to the spam filtering service, and then the filtering service sends the emails to the Exchange Server. That part works great.
The problem is when we try to add an account to Outlook or a smartphone, it won't connect to the Exchange Server to setup the account. The only records changed were the MX records. Autodiscover, mail.{domain].com, and autodiscover records still point to the Exchange server.
Here are the error messages I get.
If I manually setup the Outlook profile putting in the mail server name (mail.{domain}.com, domain\username, password, etc., then I get this.
I ran the Microsoft Remote Connectivity Analyzer for Activesync, and it passed.
The autodiscover records look like this.
A autodiscover.mydomain.com XXX.XXX.XXX.XXX where XXX.XXX.XXX.XXX is the server public IP address.
A mail.mydomain.com XXX.XXX.XXX.XXX where XXX.XXX.XXX.XXX is the server public IP address.
SRV _autodiscover._tcp.mydomain.com 0 443 mail.mydomain.com
Some people use a CNAME instead of an A record for autodiscover.mydomain.com. I don't know if that makes a difference.
Anyone have any ideas or workarounds?

Any updates so far? If you have solved your problem, could you share with us? Maybe it will help more people with similar problems. Don't forget to mark it as answer, this will be easy for other community members to find the useful one.
the outlook client doesnt support ActiveSync.
Does it work if you use Outlook Mobile on a Mobile device?
There is now an issue with creating profiles from the Control Panel (which has been our process for years). When you select manual setup, you have three options:
The only one that makes sense at all is Exchange Activesync, yet it's not supported by Outlook. I don't understand. Why does it give an option that's not supported? Where is the option that is supported? They need another option "Standard Exchange Connection".
Yes, we can connect with mobile devices, including Outlook Mobile.
Edit:
The bottom line is you can only create Outlook profiles for an on-premises Exchange Server within Outlook itself. We successfully created profiles now using this method.
Hi,
Welcome to the Microsoft Q&A forum.
When this message comes up, click Back, select Manually configure server settings then click Next.
You'll need to enter your account information and server names then click More Settings and configure your SSL or TLS settings on the Advanced tab.
Also, I recommend you update your SPF records to include the spam filtering service. If you're using DKIM, make sure the service is correctly signing outgoing emails.
I appreciate the help.
I don't get to the option of more settings. I just end up with this.
This option is in this screen：
click Back, select Manually configure server settings then click Next.
