Hi Jessica Lavigne,

Thanks for reaching out, hopefully you already came across the steps in this article which applies to the below issues including the one you experienced: Error "This shared company is already open."

The main step involves accessing the computer which last accessed the file. It likely has the most recent copy of your data.  Disconnect the computer from the internet and see the KB for step by step instruction on how to save a copy of the disconnected data so that you can reopen it. 

Once the file opens and you've verified that it has recent work, reshare it onto Remote Data Access using the steps in this blog on how to replace or re-share a Sage 50 CA company file for Remote Data Access. Hope this helps!

Warm Regards, 
Erzsi

I am having the same problem and going through the steps in KB 107248 did not solve the problem.

Hi [email protected], thanks for reaching out. I see that perhaps you've already had a callback with my colleague Alexandre and this is resolved?

Hi, I solved the problem with your colleague and then my colleague wanted to access the company and the same problem occurred! He didn't even manage once to get access. Fortunately we always make a back-up and have been working with that again but we need to both have access at all times on the shared company and that doesn't work! 

I try to open the shared company online and for a long time it says: 'Please wait while we synchronize and update your data' and then it says: 'This shared company is already open.'
