I hope they do offer us Outlook access. Because I know I love using Outlook to check my AKO. And with the CIO/G6's desire to shut down our AKO account, it does make a lot of people angry that we will now be losing our Email for life.
And yes, now you need to purchase a lot of Citrix licenses in addition to the other software. ie: ActivClient.
I truly doubt DISA will open up the email server to commercial IPs like they did/doing for TED.
In reference to ActivClient licenses, that is a DoD wide-license and as for Citrix, the licenses are for simultaneous server access. The Citrix client is free.
