I faced same issue recently, microsoft told me to disable the cache mode before moving the mailboxes. Big Pain.

it seems you autodiscover service is not working properly, you can test it from Outlook by holding ctrl key while pointing to Outlook icon and test E-mail autoconfiguration, fro there you will see the errors, most likely it will be in the names set for autodiscover URL or certificate.

You may also try to exclude the URL of autodiscover "the server name by default" from web proxy in I.E and test one machine, if it worked you can enable it by GPO to all machines
