unexpected error exporting a list to excel

Hello,

I receive the following error “An unexpected error has occurred. Changes to your data cannot be saved”, when exporting a list from SP 2010 site to Excel 2013.

This occurs when I display a specific view containing only a specific content type items.

I can export to excel the same list on another view "AllItems", but the items with my custom content type are not exported.

What's more puzzling is that another user can perfectly export to Excel 2010 on his PC (even with custom view).

This sounds more to me as either an I.E. config. problem or an Excel 2013 problem or config.

Thanks for help !

Don't know if that is linked to this issue, but : ...

- When I try to switch to datasheet view, on "AllItems" view I get "Cannot connect to the server at this time. You can continue working with this list, but some data may not be visible". And indeed the list doesn't how my custom content type items.

- When I go to my custom view (filtering on only my custom content type items), I get the same message as above and nothing displayed in the datasheet view. The view bottom line says "Unable to retrieve all data"
