Outlook Web Access Loading... in mixed Exchange 2003 and 2007 environment

There are plenty of web sites that can help you resolve now already well known problem in OWA when your browser does not display any pictures in it and hangs with Loading... text.

Use Google to find other resolution if it is not the one described below.

You setup Exchange 2007 into the existing Exchange 2003 environment. You reroute Internet users to use your new Client Access Server (CAS) for OWA. CAS server includes a mechanism that redirects user to the correct Exchange server, being that Exchange 2003 or 2007. It depends on which server the mailbox resides.

In the case that you changed Authentication type on your CAS server such that users don't need to provide domain\username but only username, your Exchange 2003 users could get following screen in their browser...

owa The resolution to the problem is in the authentication type on your CAS server. Not only that you need to change authentication type on your /Exchange folder but also on your /owa and /Exchweb folders.

Authentication

I would also recommend that you enter your domain name on existing /Exchange and /Exchweb Exchange 2003 web folders in IIS if you chose to use only username for login.

    To solve this problem I fix my IIS configuration. On Exchange virtual directory - Security Tab, enable Basic Authentication and disable Anonymous Access. And ExchWeb Virtual Directory, enable Anonymous Access and disable Basic Authentication.

    Good Luck!!!

Netscaler vs Exchange 2019 "time out during ssl handshake stage

If you are using Citrix Netscaler as load balancer in front of Exchange 2019 server you must know this: Microsoft Exchange 2019 is secured by default and allows only TLS 1.2. Therefore default schannel settings are as follows (using IISCrypto tool from Nartac Software): While Citrix Netscaler offers following Cipher Suites: TLS_RSA_WITH_AES_256_CBC_SHA TLS_RSA_WITH_AES_128_CBC_SHA TLS_DHE_RSA_WITH_AES_256_CBC_SHA TLS_DHE_RSA_WITH_AES_128_CBC_SHA TLS_DHE_DSS_WITH_AES_256_CBC_SHA TLS_DHE_DSS_WITH_AES_128_CBC_SHA TLS_RSA_WITH_DES_CBC_SHA TLS_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5 TLS_DHE_DSS_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT1024_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA TLS_DHE_RSA_WITH_DES_CBC_SHA TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT1024_WITH_RC2_CBC_56_MD5 TLS_DH_anon_WITH_DES_CBC_SHA TLS_DH_anon_WITH_AES_128_CBC_SHA TLS_DH_anon_WITH_AES_256_CBC_SHA TLS_DH_anon_EXPORT_WITH_DES40_CBC_SHA Now, you will fi

Exchange Admin Center language

Depending on your computer language settings, Exchange Admin Center can take those and open in a language you actually don't want to use. You'll Google that this can be changed if administrator/ admin user has mailbox by openening OWA settings and changing Regional parameters. But usually Admin user does not have mailbox or you don't want her/him to have it. You will search again and find that you can add mkt=en-US (as an example) to the URL of the Exchange Admin Center (https://yourexchangehostname/ecp?ExchClientVer=15&mkt=en-US) Third option you have is opening Internet Explorer settings (I am using Windows 2016) Click languages Click Set Language Preferences Add language you want to use by clicking Add language Use Move up or Move Down options to put desired language on top Close Internet Explorer Open it again and login again to Exchange Admin Center
