Thanks again - I downloaded an Office 2016 ISO and the KMStools.exe. after doing a system image, I plan on uninstalling the current C2R and deleting the current KMS portable I have been using. THen installing form the ISO and using the new KMS tool. I presume the PST files stay in tact. Are there any other steps I'm missing to get to a disk install ? I have to comment though - for Apple to not get iTunes compatible with something so common as Outlook 2016 is sad. Its been about 8 months so far and asking people to uninstall Office to accommodate their inefficiency is rude at best.
Thank you for the suggestion - IIRC in OUtlook 2016 I can use the PST file to create the email accounts all over again using the file as a reference. I also downloaded MSToolKit - do you have a preference between that for an ISO MSI install or the KMS tool ? There are thousands of posts and its a bit hard to determine which is preferred.
