Solved Windows Mail client not opening with Win 10


Active Member
Is anyone else having problems using Windows Mail client with Win 10 preview? For the last couple days, I haven't been able to open the Windows mail client. When I open it, it starts then immediately minimizes to the task bar. Once that happens, I can't open it at all. Each time I try to maximize it, it pops open for a couple seconds then shuts right back down to the task bar.

Anyone else seeing this?

<edit> It is also happening with People and Calendar.
All the same app, I had that happen to me today on W8.1. uninstall and reinstall took care of it and didn't have to reconfigure but it did resync all mail.
More Information: The built in Mail app is also the People and Calendar apps.

To uninstall:
  1. Press and hold Mail
  2. Select "Uninstall" on the bottom menu.
Your accounts and settings will be remembered.

To reinstall:
  1. Go to the Store search "Mail"
  2. Select the "Mail, Calendar, and People" app published by Microsoft.
  3. Select Install
Note: If "Install" does not show up, you might have to wait a few minutes for the uninstalled status to sync with the Store. Go back to the list or search again until "Install" appears when the app is selected.
