Hey there, @robertheit. 

Thanks for following the thread and letting us know that you're also having trouble opening the company file. 

I wanted to ask if you have tried the steps provided by my colleague Giovann listed above? If not, I encourage you to give them a try. Those are typically the best steps to take when having issues getting into the company file remotely. Ensuring the networking and file sharing is set up properly is key to opening the company file from different computers/users. 

However, if you have gave those steps a shot, are you getting an specific error message? If so, could you share a screenshot? 

I want to make sure we get you back on track to get you back to business.  Please provide any additional details that you can. This way, I can know what route to take based on what you've tried and haven't. 

I'll be sure to keep an eye out for your reply and look forward to chatting with you soon. Take care!
