Hi Gkata,
I had this same (infuriating!) problem and fixed it thusly:
Right click on the systray area
select Properties
then select Notification area > customize
At the top there is a link to "Select which icons appear on the taskbar"
Go in there and toggle whatever setting you see for your dropbox icon.
Exit out -- should be fixed.
In my case the dropbox icon was set to "on" and I toggled it off. After exiting the dialog, I had my dropbox icon back in the "show hidden icons" area. I repeated the above and toggled the dropbox icon back to "on" and now it is back in my systray where it belongs.
I hope this helps someone.
Gkata - I'm sorry this didn't work for you. However, I did what you did (togged it off & then back on), and the icon immediately showed up. I hope this is helpful for others.
Thanks
Hello, wondering if you have ever fixed this. The exact same thing has happened to me and I have tried everything you have tried. I realize your post was more than 3 years ago, but I am desperately trying to fix this.
Hi Walter, thanks for reaching out. In fact I have been working with Dropbox support on this for a week. I did try uninstalling and reinstalling, including the "advanced" uninstall/reinstall. I disabled all virus/firewall stuff as well. I even did a system (Windows 10) reset (the simple one- removing all apps and reinstalling Windows, but leaving all local documents), and that didn't work. In the end I reformatted my entire computer and started from scratch. That worked, but was a pretty dramatic solution. Thanks for checking in, you can reach me privately if you want the case number for the customer service ticket and want to follow the entire process.
