Configure Excel Calculation Services on SharePoint 2010

Sometime we can’t open excel file in SharePoint pages. Looking event viewer you see “There was an error in communicating with Excel Calculation Services”. If this is happened, following steps:

– Open IIS then go to “SharePoint Web Services Root” application pool

– Verify that Identity property of this application pool is setting to the SharePoint farm account like this (It’s must be DOMAIN\account.)


Hope this help!

    Thank you so much! I had this problem with Excel Services and Access Services and I’d been unable to resolve it for a couple of weeks. Your solution worked perfectly (my SharePoint Web Services Root app pool was stopped and not set to run under the farm admin) and I didn’t see this solution anywhere else online. Thanks for posting it.

    I was thrown off because another article ( says about the SharePoint Web Services Root app pool “it’s absolutely OK that this Application Pool is stopped.” Obviously that’s not true.

    A motivating discussion is worth comment. I do believe that you should write more on this subject, it may not
    be a taboo matter but generally people don’t discuss such topics. To the next! Many thanks!!streetdirectory
