Did update this morning & now stuck at synchronizing folders on the bottom with a spinning arrow to right of the email address in the left pane

I am getting exactly the same. There appears no way to repair it other than to remove program and re-install. i dont really want to do that as one of my accounts is pop3 and is a real pain to set up. Any ideas please. Only happened since a same upgrade.

Hi Dave, Hi Doug, what version did you recently update to, can you please check the current version of your eM Client in Help > About?

What mail service(s) are you having issues with? Does this affect a single account or all your accounts?

Are you seeing any errors?

Thank you,

Hello Paul, Version 6.0.21372.0 Using Gmail and Orangehome.co.uk both say connecting which suggests a network problem, but everything else connects. and the syncing of the gmail folders… Thanks Doug

Hi again Doug, does this mean you Gmail folders are still being synchronized?


Hello again Paul., I have just installed a windows update that popped up. Net Framework 4.5.2 for windows 8.1 and after the reboot EM client is working without notifications. See how it performs. Thanks Doug

Glad it works, please make sure to let us know if you come across this or any other issue or question again, we’ll be happy to help.

Thank you,

i get this same problem on v6.0.22344.0. Further testing has revealed that it can be temporarily overcome by shutting down emclient and re-opening it, then all the accumulated pending emails will arrive. I have also discovered that the problem doesn’t appear when connected to the internet with a reliable fast connection, but when in locations with poor internet (eg high latency such as satellite and low bandwidth) it happens regularly.

Are there any logs I could provide that would help to identify the source of the problem?

I am having problems with synchronizing to G Mail also. Keeps saying Failed to upload contact " new name each time".
Modified both on remote server and locally, either overwrite local or remote.  

Hello, this means the program has a different version of the contact on the server than in your client, this is unfortunately a conflict the application can’t resolve itself - as this might result in either duplicated contacts/merged or removing one of the copies you’d like to keep - in order to resolve the issue you need to select if you want to overwrite the local (eM Client) or remote (server) version of the contacts.

This can occur if the item was modified while the application was offline or in case another device has edited the item.


there is no error message associated with the original problem being described here, just the spinning indicator and the statement that it is synchronising folders. What can we do?

Hello, what mail service are you using with eM Client? Can you please try to update to this release, 6.0.23144.0 and check if the issue persists? Please make sure no security application is blocking the connection to your mail server and that the application is able to access your server.

If the issue persists, please let me know.


hi Paul, thanks for your reply. using it with a cpanel based mail server. i’d love to update but when i click help-check for updates it says no update available. suggestions?

Hello Stephen, we’ve released a new update, you should be able to update through the check for update option soon, or use this link to download the update directly, 6.0.23181.0 .


i’ve checked the current version with a/v and firewall disabled, doesn’t help. upgrading now, thanks

i upgraded today to the version you suggested and that made no difference. so i looked in the advanced settings and turned on logging of communications and I think we’ve got a clue. It looks like there is a bug that if a communications timeout occurs it never tries again and just keeps the icon spinning. It is now 9:27pm and the last log entry was over an hour ago when the timeout occurred. The icon is still spinning and it still says downloading messages in the status at the bottom of the window. here is the relevant part of the log:
20:20:13.205|00F| System.Net.Sockets Verbose: 0 : [8412] Socket#16978741::Receive()

20:20:38.295|004| System.Net Error: 0 : [8964] Exception in HttpWebRequest#15647122::GetResponse - The operation has timed out.
that is where the log stops.
I hope this will help you fix the fault. If I can help with any extra information and testing let me know. I was about to buy 100 licences for my organisation but now I’m having second thoughts until I know this problem is fixed, because all our connections are this slow and if this is what happens it is going to be a problem for all our users and I can’t afford to inundate my helpdesk with this issue. I look forward to hearing from you. Thanks, Stephen

update: then i closed emclient and this was written to the log next. It seems to indicate it was just stuck in the process despite the timeout earlier. I hope this helps:

Hello Stephen, unfortunately this doesn’t help us resolve the problem, I’m not really sure what mail service you’re using for hosting your company accounts, but please note that the default timeout settings are setup for 30s in eM Client, if the application doesn’t receive a response from the server within this period the request will timeout, as you suggested this can occur on slow unreliable internet connections.

Base on the first log, it seems like the application is being blocked by an external element - your AV perhaps? -  A blocking operation was interrupted by a call to WSACancelBlockingCall.

If you’re having issues while receiving email on your work station, please navigate to Tools > Settings > Advanced and enable incoming service logging (POP/IMAP or Exchange, based on your account type), and replicate the issue. Once the issue reoccurs, please restart the application and go back to the advanced settings window to submit the logging data.

Submit the logs to my work mail, [email protected] with a reference link to this forum topic.


Dear Paul, I sent logs to you on the 6th of September but I haven’t seen any reply from you so I’m wondering if they even reached you. Please let me know.

Hello Stephen, we’ve run through the logging data you’ve submitted, but unfortunately there’s no error thrown in the logging data, however it seems most of the log files are empty, thus I believe the application may be blocked or can’t connect to the server at all, others seem to show no issues while connecting to the server.
