Sync problem with Special Character on Onedrive for Business

[Tony]

Thanks for the screenshot. I remembered there being a strange issue with OneDrive inconsistent behavior with the “&” character with their API and I dug up this post:

Need to understand why so many files fall under Not Allowed when syncing

So after a little bit of head scratching I figured out that OD4B will not allow a “&” in the file name on upload. It does, however, allow you to rename a file to a name with “&”. It will also allow a folder with a “&” in the name. The bottom line is that you will need to remove the “&” characters if you want to upload to OD4B.

I believe this has more to do with a limitation of their API than an actually back-end limitation, but it is a pain nonetheless.
