This software needs some urgent updates since the installation pack Office 365 Business didn't install OneDrive on Mac and the credentials used on Word, Excel, PPTm Outlook are not valid into OneDrive. The user must find tech docs spending hours and proceed some techs steeps in order to get logged in. It spends too much time and energy and must be fixed due there is no reason to have the same credentials integrated into all Office 365 apps. Also, I don't understand the reason to keep OneDrive out of 1.3G pack downloaded during installation on Mac. Also, the credential issue is happing for PC users and a ticket must be raised to get support and solved. For final, lots of problems with sync service where the software is not be able to manage "too long files/folders names" and stopped the entire sync and after some renews app is totally disconnect reporting 301 errors and no one knows how to fix. Looking into communities users are reporting the same problems and someone must take a look in more details. Users can't expand too much time and energy to have this up and running as it should be. Take a moment to test and trial others softwares and you'll see that any business user can install with no it support and get it running in minutes. This is the second day and opening new ticket to get support again. Nowadays, this level of deployment and difficulties doesn't make any sense to me - Office 365 Business.
