Windows Explorer bad behavior with xlsx file

[EricLEBRUN]

Hello,

Could you help me to fix this stange behavior with Windows Explorer ?

The environement is a Windows Client with a volume share on a CDOT Data ONTAP v9.1P12, CIFS SMB V1.0.

And scenario is:

- Put Windows Explorer on same folder than file test4.xlsx - k:root\Infra\Test
- Open k:root\Infra\Test4.xlsx file with Microsoft Office Excel
- Make changes on file k:root\Infra\Test4.xlsx
- Save it  <- OK

- Put Windows Explorer on upper level folder than folder of file test4.xlsx - k:root\Infra
- Make changes on file k:root\Infra\Test4.xlsx
- Save it  <- Error (Document not registered)

Important points:
- Error occurs only with xlsx and sometime with xls extensions
- Error occurs only with Microsoft Office (2010, 2013 and 2016)  and never with OpenOffice
- Error never occurs with 7-Mode NAS

Thanks in advance !

I have a few questions to ask you about this problem:

1. What is the security style of the volume you're having a problem with?
2. Where is the temporary file directory for Office kept?
3. Are particular users running into this issue or only some?
