My Windows 10 e-mail started running extremely slow all of a sudden. It's the standard e-mail program that comes bundled with W10 software. How do I fix it ?
Not sure since you have no network description in your system specs and who the e-Mail service is. I use Windows Live Mail on our PC for e-Mail from our ISP’s server over a 100 mbps connection. The e-mail service is sourced by Two-Cows on a different server somewhere. I sometimes see slow speeds of receiving new e-mail and it always traces back to the e-mail server and its link to the ISP’s servers. I can also tell by using a web based e-Mail program to access my e-mail account.
Assuming you have all your Mail Account(s) details to hand so you can enter them again...
Settings > Apps > Apps & features >
Scroll down to Mail and Calendar, click on that > Advanced options > Scroll down to Reset.
Also:
MS Store > 3 dots > Download updates > Get updates.
This is just to ensure you have the latest iteration.
I reset the automatic update for the mail and two days later the problem disappeared. Mail is running as is should.
