We are performing a manual cutover from SBS 2008 (Exch 2007) to Office 365. We have all the email accounts backed up and Office 365 (with Outlook 2016) is installed, but we can't get the mailboxes / accounts setup in Outlook 2016. When we try to create a new Outlook profile, it is still finding or seeing the local Exch 2007, but I want Outlook 2016 to use the new external Office 365 settings. It's like the PC is remembering or knows that SBS Exch 2007 still exists, and so is using those settings, and not even trying to look externally for the email hosted O365 server settings. I think I have the DNS, SRV, MX records correct for Office 365 & domain. How can I force the PCs to NOT use the local SBS or local autodiscover records??
