Can’t link/pair two Dropbox accounts
I'm trying to add a second Dropbox account (e.g., personal and business) but receive an error.
Quick Guide
- Sign into one account via the Dropbox desktop app.
- Under Preferences → Account, click Add team account.

Common Causes
- Desktop app bug or corrupted cache.
- Browser/auto-fill issues during web linking.
Possible Fixes
- Fully uninstall and reinstall the Dropbox desktop app, then re-add accounts.
- Clear cache/cookies or switch browsers for web linking.
- Make sure each Dropbox account uses a unique email address.

Quick Guide
- Go to dropbox.com → Settings → Third-party apps.
- Review the list of connected apps/services.

I want to select specific files instead of entire folders for sync.

"This email is already taken" when changing email on Dropbox Account
I tried to change my account email, but get an error stating the new address is already in use.
Quick Guide
- Make sure you’re not trying to use an alternate email that’s already on another Dropbox account.
- Log into dropbox.com with that email to check if it’s already registered.
- If it is, unlink or change it on the other account first.
- Then retry changing your email on your main account.
Common Causes
- The new email is already linked to a different Dropbox account (perhaps one forgotten or older).
- Someone else has already registered the same email with Dropbox.
Possible Fixes
- Recover access to that account via “Forgot password?”, then remove the email.
- Choose a truly unused email address.
