Hi all,
I installed an Exchange 2010 server (CAS, HUB and Mailbox role) on Windows 2008 R2. I have published the following ports publicly to 117.185.xx.xx (SMTP: 25/587 POP: 110/995 IMAP: 143/993 HTTP and HTTPS).
I have created the DNS records for autodiscover.domain.com and mail.domain.com. I was able to complete the RCA Autodiscover test, connect the mailbox in Outlook 2013 desktop from Internet. I can log into OWA and ECP using the URL https://mail.domain.com/ecp(owa) and https://autodiscover.domain.com/ecp(owa).
I decided to deploy a Hybrid with Office 365. I have completed the Hybrid Configuration Wizard but got an error.
After I ignored the error, I can migrate the mailboxes from on-premises to the cloud with remote migration. But I failed to view the Free/Busy information from cloud to on-premises. Running the RCA test from Free/Busy, I got the error in the report:
Verifying connectivity to the specified endpoint

Appreciate any insights from you.
