Hello Tony,
Thanks for your quick response.
All folders that I need have been set to sync and I double checked the subfolder as well, so that is not the issue.
These are the error notifications I receive:


In the folder of the excel file I have mulitple VBxxxx.tmp files., also the one that is not being accessible.
It looks like that VB1999.tmp file is being created once I try to copy the sheet and it cannot be accessed (on time)?
So for every attempt I have a new tmp file that cannot be accessed.
The file has no connections and links.
What do you think can be done here?
