Hi Phil, 

Welcome to Box Community and glad to help! 

Did you check if the email where this collaboration invite was sent is the same email you're using to log in to your Box account? 

If yes, try to log in to your Box account first and accept the invite again. 

Hope it works! 

I'm having the same issue, and yes, I'm logged in to the same email where the collaboration email was sent

Hello! I am having the same issue. I click "accept invite", browser opens, I log-in to box successfully and the file/folder being shared is not in my list of "all files". Sender has the right email & I have successfully accepted invites from colleagues of sender.

Hello, I'm having the same problem. I double checked that the email the invite was sent to is the same email that I'm using to log into Box. I see the folder nowhere in my files. 

Hello. The same happen to me. Any solution?

I am having the same issue was this resolved? 

Hi,I have the same problem,any solution updated? Very appreciated if can share,thanks!

I have the same issue. It's very urgent has anyone found a solution? 

Same issue. I am surprised there is no answer on this thread with so many people having the same problem over the course of a year. And that there is no way to get one on one support for such a major issue. If anyone has figured this out, could you please point me in the right direction?
