- You enable Remote Desktop on a computer (computer A) that is running Windows 7 or Windows Server 2008 R2.
- You configure an Outlook 2010 client that is installed on computer A to save Personal Folder (.pst) files on another computer (computer B). Computer B is a file server that is running Windows Server 2008 R2.
- You establish a remote connection to computer A from a client computer, and then start Outlook 2010 in the Remote Desktop session.
Windows was unable to save all the data for the file file path. The data has been lost. This error was returned by the server on which the file exists. Please try to save this file elsewhere.
- You have mapped a network drive to a server share and you use offline files to make the data on this share available offline.
- You have a MUP filter driver installed (e.g. disc encryption Software).
- You try to open a file (e.g. a text file) of a given size from this share while you're connected to the Network, although the actual SMB Connection to the server is not yet established.
In this Scenario, you might get the this error message:
If you click on OK the text file will be empty. If you now close and open the file again it might work.
This issue occurs because the Outlook 2010 client tries to write data to an open SMBv2 file ID that has read-only access.
This issue occurs because the offline files client tries to read the file from the server before the actual SMB connection is established.
