I know Microsoft has EOL'd 2003 server.
Server is used as local exchange server with some users accessing via OWA or MobileSync. Server had an old SSL cert long expired. Company would like to migrate to Office365 so was investigating a staged migration. Necessary to that is a proper SSL cert for Outlook Anywhere.
Created file, got cert from Comodo, installed it to the personal certificates section of the Certificates MMC. Went into IIS manager, OWA properties - Directory Security, replaced the certificate with the new one. Doing a view certificate shows the proper data good for another year, says it is OK. I also turned off the check for 'enable anonymous access' in the authentication methods tab. Integrated windows auth and basic auth are checked.
Need advice to get this webmail working on https.
