Re: Access Services is unable to process the request.

Hi HEN,

Sorry that I have made you confused. I mean that could you try to save the Access as a local database then re-publish it to the website, to narrow down the problem in case it’s a database issue.

However, from your post above I notice that the database works fine on your computer, which proves that the database has no problem. Based on the situation, I recommend you to try the solution in the following link to solve the problem:
