Rated 4 out of 5 stars

I've been using this add-on for a couple of years, and it has worked well thus far. I just wish there was a setting to delete linked files after a set time (60 days, maybe). Otherwise, I have to remember to remove the files if I want to save space in Box. But, overall this is a great add-on.

Works great, when it works. Having a problem with the extension timing out. If we have Thunderbird open for a few hours and try to link a file we get an error. If we quit the app and do everything the same, it uploads the second time. (same files, same email as we save it as a draft before quitting).
