Synchronizing folder list failed with an error: The remote server returned an error: (404)

What version of eM Client are you currently using on your computer, can you please try to install this update on your computer and check if the issue persists? http://www.emclient.com/dist/v6.0.22065/setup.msi

Thank you…

Avram_Stanton · April 3, 2015, 11:33am

I was not using the version you offered. I updated to v6.0.22065 and the error is still persisting. In addition, it appears that after updating I am no longer receiving emails from my office’s exchange server at all. Also, the application keeps crashing, fatally is basically unusable. I’m going to try uninstalling the application entirely and reinstalling using the version you provided.

UPDATE: Paul, I’ve had to uninstall the application permanently as it no longer functions at all. Another point to mention is that uninstalling the application does not appear to remove it. After reinstalling the problem came right back but it restarted as if the application was never removed, meaning a large portion of data (user settings, emails, contacts, etc) were never removed during the uninstall. Its possible a corrupt module could be in those reused remnants.

I’m sure there is some type of cleaning utility your company has that completely purges it from my computer, but the standard .msi uninstall does not do that. There is something slightly off-putting about software that lurks on a hard disk, occupying space.

In the meantime, I’ll need to hastily figure out how I’m going to get my company email!

eM Client does not remove user data when uninstalling, in order to remove your database you’d have to navigate to your user/App Data/Roaming folder and remove the eM Client database data.

I’m afraid the 404 error may be caused by an incorrect setup of the application, most likely the application was unable to connect to the server using the setup address, please make sure the server address in your account setup is correct.

Also please note that as a free license user you’re not entitled to use the application for business or commercial use, this requires you to use a valid PRO license. Unless of course, you’re still in the demo period.

Paul_Technical_Suppo · April 3, 2015, 12:08pm

Also if you’re using any security software on your computer such as firewall, proxy or any antivirus software with email protection, please try to temporarily disable these security elements and check if eM Client is still unable to connect. As some security software can be disabling the application’s ability to connect to the server, in some cases.

If such case occurs, you’d have to setup an exception for eM Client to connect to your mail server.

Avram_Stanton · April 3, 2015, 12:25pm

Yeah, this is a test drive. I’m fairly fed up with Outlook and was looking at alternatives. This seemed to be the most fully fleshed out and would purchase if it is a viable replacement.

To repeat, the application was working fine, minus the 404 error, before the last update you gave me. It now immediately crashes on startup.

Paul_Technical_Suppo · April 3, 2015, 12:59pm

If the application crashes, can you please display the error and submit the error content to us here for more information?

Steven_Fishman · June 19, 2015, 12:49pm

I am also having this same error

Paul_Technical_Suppo · June 19, 2015, 2:22pm

Hello, this is an outdated topic, can you please create a new topic and describe the application’s behaviour? Please copy the log content from Operations when the error occurs and include it in the post. Also please check the exact release number of your eM Client in Help > About.

Thank you,

I have been getting this error for some time now. It seems that I am getting and sending email, but these continuous error messages are annoying. Here is the error log:

Hello, can you please try to re-setup your account in eM Client or step the account from scratch and disable your current account in Tools > Accounts and check if the issue persists? I’m afraid this issue is connected to the recent change of the authentication method Google has been using with their account. Re-setting up the account should help you get rid of the issue.

Regards,

Doreen_Burnham · October 24, 2015, 7:49pm

I tried re-doing the accounts, made no difference - error still persists.

rpgmaker · October 24, 2015, 8:24pm

It’s ridiculous that this error still occurs. I’m unfollowing this since it’s so obvious they aren’t going to fix this.

Avram_Stanton · October 25, 2015, 9:16pm

Yeah, I gave up on emClient a while ago.

I have this same 404 error (synchronizing folder list fail) using Office 365 exchange ever since I set my email on emclient about 3 months ago. When are you guys going to resolve this?
