too slow when openning the mailbox and too slow of upload the attachment!!
Dear Yahoo Technical Team,
It used to be too slow when openning the mailbox and too slow of upload the attachment!!
Can't just be smooth of using this mailbox, and it's too slow after 5;30 p.m.!

If you still find that the issue is happening, please see this help page for troubleshooting:

Unable to sign into Yahoo web based mail using Windows 10 computer. If I do get in it's extremely slow to the point I keep receiving a message from Yahoo stating their engineers are looking at the problem. This has been going on for 2 weeks now and no support from Yahoo. Can't Yahoo have a little more interaction instead of throwing it on their user base to support their application.

It was working just fine until today, but it has become terribly slow today. I've never had a problem like this until today. I've migrated from Microsoft Outlook, hoping to avoid connectivity issues using iphone, etc., but now that Yahoo has gotten so slow, I'm beginning to wonder if I need to explore another option?

Stop rearranging UI functions and introducing bugs to features that used to work. Focus on performance and ensuring the features offered actually work with consistency and stability. Ever here of the concept of regression testing?

How I can return to my old Yahoo Mail format?
-
Hector Salvador commented
The best idea is that you return me to the old format. Otherwise I will move to Gmail. And will forget Yahoo Mail

Colleen Morris commented
I will definitely be trying to return to the old format.

Yahoo mail has been running slow for 2 days Feb 5 & 6 2018, and it crashes. Please fix the problem

Please fix your servers or figure out how to get everything running faster and efficiently.

I can't load emails, can't send emails... this is brutal. Yahoo Mail has basically been "down" since about Noon ET on 2/05/18, and it's now 9:30 am next day. This is unacceptable for those of us who rely on email for business communications. Stuff like this is pushing me closer and closer toward switching to Gmail.

It is impossible to open saved mails, it circles around! Your IT team is thumbs down!

What has become of Yahoo! mail since a couple years ago? It has become slow and very unpredictable. The new icons are not as good as the older ones. Can not Yhoo! mail improve instead of becoming worse?

It's obvious that any mail system must be fast, reliable, and have 100% uptime. This new mail offers none of these.

What if the download button worked? That would help... Slow like **** and nothing happened in minutes.

I hate Yahoo Mail so much. What a garbage way to treat your customers with a tragically flawed mail system like this. Just pathetic.
