How do I setup an Exchange account in Mail.app in Mac OS X lion?

• I have succesfully setup my account in iOS 4, with the following details: Server: http://m.regionh.dk Domain: regionh SSL: on The webmail address is https://m.regionh.dk/Exchange I believe the internal server address is HEEX0005 In Mail.app: Should I use 'Exchange' or 'Exchange IMAP'? Incoming mail server address? Outlook Web Access server address? Internal Server address?

• Answer:

  This is all going to be dependent on how your Exchange team set up services for the Exchange environment and what version of Exchange you are using. I believe under OS X 10.7 (Lion) Apple Mail app Exchange 2010 is called for and uses EWS to natively talk to the Exchange servers. You will certainly want to use Exchange although if your administrators have enabled IMAP for your mailbox you can use that as well. Assuming you are on the internal LAN while doing this: So for Exchange OWA name would be the same as you provide Exchange server should auto config once you enter your email address if they have the right records set up in DNS and your Mac is bound to the domain (although not necessary). If not, you can use the server name but I would add the FQDN of the server: http://HEEX0005.domain.com
