As of today one specific user is having issues opening Excel documents from a Sharepoint 2010 site. Whenever he tries to open one he gets the following error message. The screenshot is in Dutch but the message reads:
Unable to connect to the server.
The file {filename} cannot be opened because a connection can't be made to the server.
[Open again] [OK]
This is not a newly created website nor is it a new user. He has never had issues opening Excel documents in the past. There's nothing wrong with his network connection.
Tried solutions:
- Reset Internet Explorer settings
- Repair Office installation
- Restart computer
But the issue remains.
