I have tested again, the problem is in dns + SOGO.
Found this also, and i think that this is the problem:
Sorry, I thought that is a new installation and you have problems with receiving emails. I didn't read too careful.
If activesync takes the internal domain, is correct to have invalid mx record.
The MX record must point to the FQDN.
Maybe is something wrong with the DNS, network configuration, firewall, ..., after the update.
Maybe is not related directly to SOGo.
The updates were for SOGo?"
Directly from SOgo works ok, SMTP/IMAP account in Outlook works OK, only activesync problems, but only on send, receive works fine.
