Likewise, can send but not receive from the server. Hope they fix it soon.
Wow, this probably explains why Im not being provided 9.1 update when I check for updates ( despite the email I got offering it!). Unit testing framework broken again? 
I added “export.” in front of the imap address on my account (someone else’s suggestion)
and it worked for me. maybe worth a try

Could you type your IMAP server address in this thread you put in eM Client to fix this issue with the “export in front” as you said for an example fix.
As I would have thought putting the word export in front of an incoming mail server address would normally error straight away. So interested to see how you typed in your IMAP server address.
in your server settings put "export.imap.mail.yahoo.com, use ssl, port993 and use requires authentification
Ok. I am amazed that a Yahoo IMAP server would “even be valid” with a server address like that where from setting up my Yahoo.com account in eM Client, it works perfectly with the normal IMAP address imap.mail.yahoo.com . So im suspicious as to why they would have that IMAP address at all.
Googling on their website, i see they do specify that address as you wrote in a different help link article which is very unusual. Be interested to know why that Yahoo IMAP server address was ever created.

The suggestion/resolution is not mine, but rather from another user.
As for a very technical reasoning: I have no earthly idea

I too am a lifetime Pro user and have encountered the same IMAP connection problem using EMclient 9.1.2109. But I found a workaround.
I changed an inoperative account’s security policy from “Force usage of SSL/TLS” to “Use SSL/TLS on special port (legacy).” It worked.
I then changed an operative account’s security policy from “Use SSL/TLS on special port (legacy)” to “Force usage of SSL/TLS.” It broke, and I reverted settings. It once again worked.
If you too have this problem, set the account to “Use SSL/TLS on special port (legacy)” and try again. Please post if amending this setting fixes the problem.

Hi, I’d like to try this, nothing else has worked but I don’t know how to actually proceed to downgrade. I’ve got everything backed up regularly and recently, I’ve moved all local folder content to the IMAP folders as well. Where do I rename the database and to what name. If you could outline how to downgrade and where to find the database to rename it and to what, I’d be most appreciative. I re-downloaded v9.0.1708 (which was my previous version). Many thanks.
Yes, the security policies are very specific to the port you are using.
So for IMAP port 993 the policy needs to be set to Use SSL/TLS on special port (legacy)
This doesn’t explain why “Force usage of SSL/TLS” and port 993 worked together in all versions of 8.x and all versions of 9.x before 9.1.2109.
I can understand that the powers that be may want to couple “Use SSL/TLS on special port (legacy)” and port 993 going forward. But they should have given users warning that the upgrade could break long-working configurations.
I hope this helps those who were contemplating the “backup, uninstall latest version, install old version, restore, pray” approach.
Most likely a server that was incorrectly configured and coincidentally fixed at the time you upgraded.
For port 993 the correct policy is Use SSL/TLS on special port (legacy). So that is why it now works.
I tried various port setting without success. But after installing the Windows updates for today, all is working.
I recently booted up my laptop after about a month of inactivity. eMail Client started, downloaded messages into the inbox that were on the server , and then alerted me to an update. Update was downloaded and completed. Since then, the laptop does not receive messages. I’ve done the trouble shooting which says all is ok. I have eMail Client on a tablet, and it still receives messages. It is still a previous version 8, but says it is the latest version for that device/no update available. I use outlook app on my phone. The test message from the diagnostic troubleshooting is received on the other devices.
Can anyone help? I can send a message from the laptop but eMail Client is not retaining a copy of the sent message which is checked/selected.
I just found this thread. Why is there still a problem with update if they are aware of it for a month?
What version of eM Client do you have on your laptop ? Go Menu / Help / About.
All the latest versions for Windows and Mac are available from the version history page.
Also when you have eM Client open, go to “Menu / Operations” and click on the far right “Log tab” and see if you can see any obvious error messages in the log. Then paste the error in this thread.
One thing it can be is that eM Client needs to be online and connected to the licensing server once every 14 days or the program will only work in offline mode which might have happened.
So check via the Menu option if it has a tick in Offline mode. Also check via Menu / Help / License to see if it’s activated.
Version is 9.1.2109 (9967b93).I clicked on a link in an email that update available or a popup when I turned on the laptop. I’m still using Windows 10, this old computer is not Win 11 eligible.
8:53:53 PM Online state: changed to online due to NetworkAvailability All other things on log list is synchronizing folder list; synchronizing folder/“inbox”, etc. There are no errors shown.
License is activated. I have in the past had to reactivate and it will issue a popup notification.
Not sure where Offline mode tick mark is located. in the Menu under messages there is an option to click for download selected messages for offline use. Under File-Work offline is NOT checked.
Under Accounts-Imap settings-sync options, “Download messages for offline use” is checked. Also, I tried the export.imap.mail.yahoo.com trick, but it has made no difference.
I think that is everything you mentioned.
Thanks. Kmm
Ok. You have the latest version of eM Client and everything seems to activated ok and not offline.
So next suggest to try removing and re-adding your Yahoo account via the eM Client “automatic email wizard” at the top of accounts, as eM Client recently updated support for the new Yahoo API in V9.1.2109 which now seemed to have fixed 99% of forum user Yahoo IMAP connection issues.
Note:- Before removing and re-adding, make a backup via “Menu / Backup”. You can see when the backup is completed via “Menu / Operations”.
That’s what I was afraid you were going to say. The thought of this terrifies me, losing all my files and folder setup. I need to learn how though because these computers need to be replaced sooner rather than later. After re adding account, then restore the backup to get it back like it is now? Where is the backup to reinstall stored.
I really appreciate your advise. Thanks.
