Hi,
Thank you for writing to Microsoft Community Forums.
I understand that you are unable to get the option to put the files back to online. As you have mentioned that, you are getting an error when you try to do it manually from Sync Center, please help us with the error message.
However, you can try the following steps and check if the files get online:
- Right click on the folder/file that you want to sync online, and click on Properties.
- Click on Offline files tab.
- Clear the check box for Always available offline.
- Click on Apply and OK.
Please reply with the status of the issue, we will be glad to help you further.
Regards,
