Yahoo Mail Issues - Slow Sync / Missing Emails / Slow Message Download & Uploading

I’ve been using EM Client for possibly 8-9 years now. I have it installed on multiple computers using multiple email accounts. I really like eM Client, however, my main email from Yahoo keeps having issues like slow syncing, missing emails, slow downloading and sending (I have 500mpbs internet). I just discovered this forum and seems like others may have this issue too?

All my emails load instantly on my phone apps and webpage logins. While using eM Client on Windows 10/11, all my other services like Gmail load up very fast. It’s just Yahoo (Turbify?) that doesn’t seem to be fully connected, and I’ve had this issue for a very long time. I think it’s time to get this fixed.

That sounds suspiciously like Yahoo mail issues to me being that your Gmail account in the same eM Client works fine and Yahoo have been plagued with problems for years “with many different mail clients” connecting and synching mail etc.

eM Client did an update in Aug 2022 V9.1.2109 which fixed Yahoo connection issues “with the new Yahoo.api etc” at that time which seemed to work for myself. I personally still have no Yahoo issues.

The latest V9.2.1735 (PC) or V9.2.1838 (Mac) include those fixes from the release history page.

However as you are still having issues with your Yahoo mail sync issues in eM Client, “if you already have the latest version”, and “already tried removing and re-adding the account”, and you are using the following Yahoo IMAP settings, then you will probably need to send in connection logs etc to be diagnosed.

Server - imap.mail.yahoo.com
Port - 993
Use SSL/TLS on special port (legacy)

So if you are a current eM Client pro active customer, suggest to go to support.emclient.com and login with your registered email address & password and lodge a support ticket with these issues.

“Support for new Yahoo IMAP API (Message limit and UID Only modes”

Thanks for the detailed information Cyberzork. Looks like all my setting are right.

I stopped receiving Email from yahoo.com into my EmClient Inbox as of 12 noon on Monday this week.

My EmClient is up-to-date.

I removed my Yahoo account from EmClient then added it back again Cyberzork.

I never like doing that…

But it is working again now !
