I'm rolling out exchange 2010 currently into my server 2008 AD environment (we're in coexistence with 2003 currently). So far everything is going well, and I am working on getting activesync to work properly.
So, after I moved my mailbox to the new server, I was unable to get emails and calendar sync to my phone (Droid X) using the native app. Touchdown (3rd party paid app) works. So after doing a bit of digging, I found that if I open the ADSI snap-in, open the properties to my AD account, go to security and advanced, the "Allow Inheritable permissions from this objects parent object" box is unchecked. Once I checked this, Viola! mail and calendar begin to sync on my phone.
So, the actual question, is there any type of script that could be done to do this across the organization? I have over 450 users, a good 100 of which will need access to active sync. I'd rather not have to go about doing this manually (although running a script on my entire AD does seem a bit scary)....
