Hello,
I completed all initial steps, and tried to switch dns-records to new Exchange 2013 nlb. After that I checked connectivity for test users in Remote Connectivity Analyzer, all tests were completed successfully. Also I checked OWA, and it was fine, redirect to old OWA without any troubles. In IIS log I found a lot of errors 400 for some external users, they couldn't connect from Outlook via Outlook Anywhere, and login to OWA, or get mail by Active Sync. Most users get code 200, and they didn't have any troubles, but some did. Users from one database might get errors, and might not. So I have to switch DNS-records back. Anyone have any ideas why this is happening?
We have next configuration:
Exchange 2010: 3 mailbox servers in DAG, 2 cas/hub in nlb. Outlook Anywhere Settings:
Server ClientAuthenticationMethod IISAuthenticationMethods SSLOffloading ExternalHostname------ -------------------------- ------------------------ ------------- ----------------
cas1 Basic {Basic, Ntlm} False owa.contoso.com
cas2 Basic {Basic, Ntlm} False owa.contoso.com
Exchange 2013: 2 mailbox servers in DAG, and 2 cas in nlb. Outlook Anywhere AuthenticationMethod set to Basic
