Hi @Federico Coppola ,
Did you open the files from network location directly?
I suggest you try to add the EnableShellDataCaching value to the Microsoft Windows registry. To do this, follow these steps:
- Close your Office programs.
- Click Start, and then click Run.
- In the Open box, type regedit, and then click OK.
- Locate, and then click to select one of the following registry keys accordingly:
Microsoft 365 Apps, Office LTSC 2021, Office 2019 and Office 2016: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Open Find - After you select the key that is specified in step 4, point to New on the Edit menu, and then click DWORD Value.
- Type EnableShellDataCaching, and then press ENTER.
- Right-click EnableShellDataCaching, and then click Modify.
- In the Value data box, type 1, and then click OK.
