Error deleting FileTable - HRESULT = '0x80070490'
Due to the urgency we do not expect a return of support from Microsoft, but it seems that the error occurred due to attempt to put the database offline.

We solve the error as follows:

Since we had a base equal to the base model which showed the error, made ​​the copy of the data base with an error (except FileTable) for the base model and recreate the FileTable. It was in this way that we solve.

Because we applied the solution before the return of support, they could not diagnose prescision.
