When the users enter their credentials, are they then able to send and receive emails?

A few things to check.
1. Check that all the Exchange services have started and have not stopped by themselves recently, esp the address book service.
2. Check add-ons that have been added to Outlook profile which may cause additional authentication prompts. You can disable outlook add-ins in Options, Addins.
3., Check date and time on Workstations are sync'd with the date/time for the new AD domain. Must be within 5 mins of PDC's server time.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

I would also check the autodiscover settings on Exchange and test them to ensure they all work fine - seen incorrect configuration causing a crednetial prompt a number of times in the past.

Not sure on Office 2011 for Mac but have heard testing directly from Outlook on there can be a pain. It's usually recommended to use the autodiscover test tool here: https://www.testexchangeconnectivity.com/

Run it from the Mac and it should give you an idea if Autodiscover is working properly.
