I update OneNote 2013 to 2016, and began to get the messages: You're not connected to the internet.' I only have the option to hit 'I'll Come Back Later.' I also had OneDrive installed (regular not Business). I did have OneNote 2013 installed and it had been working flawlessly. My work computer currently uses all Microsoft Office 2010. I have been racking my brain about OneNote 2016. Great job, Microsoft! And I mean that entirely facetiously. Waste a bunch of my time, only to then tell me that they don't provide that level of support. Strangely, Onenote is STILL giving me an error about not being able to connect to the internet under the file menu, but it still lets me open my onedrive notebooks anyway? Throughout this process, microsoft support was exactly not helpful at all, but did Fingers crossed that I can still re-install and use Lync without sync issues. I'll probably skip re-installing onedrive for business entirely since apparently they don't play well together. I deleted all stored office credentials, and when I opened onedrive and logged in, Onenote seems to beĪble to sync again. I was finally able to resolve the problem by uninstalling OneDrive for Business and Lync (Skype for business), and then re-installed onedrive personal. After extensive troubleshooting, deleting credentials, uninstalling I recently installed some new updates to microsoft office on my work computer and noticed the same problem with onenote giving me an error about not being able to connect to the internet.
