This is a migration from MS Exchange server 2013 to 2016 for a small environment with 25 mailboxes. There is 1 multi-roles exch2013 and a new deployment of exch2016 server. Setup of Exchange 2016 server progress and completed successfully. After that, most of the mailboxes migrated without problem. However, we found that the URLs to access to Exchange 2016 server doesn't work. These URLs include, outlookanywhere, owa, Activesync, powershell, etc. OWA access to mailboxes still kept in exch 2013 are working. It looks like there are some of the post-installation tasks still yet to conduct, is that true?
Please enlighten what tasks need to be conduct in order to get client access part of Exchange 2016 work. Thanks in advance.
