Yahoo/Hotmail no longer syncing


Neither my Yahoo email nor my Hotmail email sync anymore.


I see “Several of your accounts are having issues” with “Check Again” or “Manage”, to which then I have to reconnect both manually.

Email Provider

Yahoo and Hotmail.


  • OS and Version: Windows 10 21H1 19043.1165
    • Installation Method: installer
  • Mailspring Version: 1.9.1-30ef802f

I know I’ve made a topic about my Hotmail before, but now my Yahoo account is doing the exact same thing… I have to generate a new password for Mailspring with Yahoo every single time I launch the program. I also have to reconnect to my Hotmail every single time. What’s weird is I have the exact same accounts synced through the Linux app, and neither of them have disconnected after restarting the app, nor the OS. What’s going on?

Hi, I’ve given up on Mailspring. I can’t send images greater than about 20k. Both Thunderbird on my PC & Bluemail on my phone have no issues at all. Shame really it looks great & scales to my 4k moniter.
