My OneDrive for business can not synchronize with Office365. We know that an update to an document or folder can çreate an error in the sync. There are some problems with OneDrive where you are not authorized by your system administrator to solve this issue. If the problem is very harsh and you or the administrator want to resolve this issue you sometime need to create a call with the Office 365 support team.
Luckily there are plenty of things you can do with OneDrive Restore.
Actually, there are always a few things you already need to do and know before you sync using OneDrive for business.
Think of it as a URL that you enter when you search in your browser each / example is a folder, but if for example you have a file with the following name “a new way to sync Version 80/20 note.doc” this causes the same problems when you use the & sign the document will not synchronize and you get red crosses.
The complete list of characters that can not be used (in dutch only).
There is also a problem when a file is longer than 255 characters. This can happen when you have a file with only 10 characters, probably the file is in a folder within a folder, etc. for example “C: \ Users \ Documents \ private \folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\folder\note.docx”
Also, there is currently still a problem that your personal OneDrive exceeds 20,000 files. a smart temporary solution isto merge any files in a .zip file if you have for example a store with lots of files you used purely for backup, it is interesting to zip these files so that for example in 2000 become one file.
