Why is the Windows 10 Mail app so slow?

When I upgraded from Windows 7 to Windows 10, I started using the built-in Windows 10 Mail app. It's got a nice user interface. However, I'm finding that it takes FOREVER to sync. Well... around 10 minutes. I have 3 Gmail accounts and one Time Warner Cable account. All IMAP based. Any other mail client I've used, including on my mobile phone syncs up in seconds.

At this rate, I'll probably go back to using Thunderbird (which syncs quickly) unless there's a solution to the performance issue.

I would follow the slogan.......................
If it ain't broke, don't change it.

It's nice and perfectly normal to try something "new". But don't let that become a burden.

And I gave my recommendation.

mbratch,
It might take some time, but please post back if you have found a solution.
If yes, which solution ?
If no, do you go back to T-bird and chose something else ?

Try this
Open Mail
Settings
Then Manage Accounts
Then click on the account you want
once open click
Change Mailbox Sync Settings
I have mine set to
As item arrives
Click Save
You should be good to go

"As item arrives" isn't a choice in my settings. Perhaps it only applies to certain account types, but it doesn't seem to apply to Time Warner IMAP, or Gmail IMAP accounts.
