Problem with Exchange and SplitDNS?

Question

Microsoft Exchange

Colleagues please tell me.
I installed a certificate on Exchange 2010 Geotrust *.company.ru, a certificate without SAN names, respectively.
The problem of the certificate with iphone and others is gone, I set up splitDNS (created the zones autodiscover.company.ru and mail.company.ru
But when starting Outlook from a domain environment, it still swears at the local computer name (comapny.local).
Where to dig? DNS about the computer Helps but not for long, re-registers and the problem pops up again Or did I misunderstand something?

Answer 1

You need to configure not only DNS, but also prepare Exchange, you can use this script: https://practical365.com/exchange-server/powershel...
PS
Stop, I missed that you have a "ten" - you need to add another CASarray there.
