Hi, after moving one mailbox from 2010 SP3 to 2013 CU1 the Outlook for that user has a wrong config in Exchange proxy settings. My external url for Outlook Anywhere in 2013 is set to mail.domain.tld but in the Exchange proxy settings Outlook is now configured to: https://servername02.domain.tld and msstd:servername02.domain.tld when I overwrite this manually and restart Outlook it's reconfigured to the settings above. Did I miss something? Thank you Carsten

Hi, That is by design. Outlook will display the Internal Hostname for Outlook Anywhere in the proxy settings. If you have split-dns configured you can change the InternalHostname to be the same as the ExternalHostname. See: Outlook Exchange Proxy Settings dialog box always displays the internal host name as the Proxy server in an Exchange Server 2013 environmentMartina Miskovic

Thank you!
