I’ve downloaded the eM Client trial and installed it to connect to my Exchange Server. All seems to run well except email with attachments around 4MB or more remain in the outbox and do not send. I’ve also used Outlook and Thunderbird (with the ExQuilla plug-in) against the same Exchange Server and they send the same emails without issue - so I’m fairly sure that it’s not a server problem.
I’d like to get this issue sorted and stick with eM Client as it’s generally quicker than Outlook and a more complete solution than Thunderbird.
Hi, sorry to see this, I’m having no issues while sending attachments larger than 4MB, can you please check what version of eM Client are you currently using on your computer? Can you please check the exact version number in Help > About?
Are you seeing any errors when trying to submit the message with the included attachment?
Thanks for the reply. The version number is 6.0.21372.0
An error message appears: “[Exchange Web Services] An attempt to connect to the_email_address failed. This could be caused by temporary server unavailability or incorrect settings. Do you want to check the settings?”. Is this a timeout issue?
Obviously “the_email_address” above has the real email address of the account.
eM Client also keeps requesting the password to the account. If I click on “OK” it just shows the dialogue box again, if I click “Cancel” everything seems to work fine.
Hi again Simon, please update your eM Client to this release, http://www.emclient.com/dist/v6.0.21527/setup.msi and disable the Offline Address Book synchronization in your Exchange account setup in Tools > Accounts.
This should resolve the password required popup issue, this issue is related to an incorrectly setup OAB service on your Exchange server.
As to the attachment sending issue, can you please switch to the “Log” tab in Operations when the error occurs, copy the content of the log and submit the log to us here on the forum.
Are you using any security software on your computer, such as firewall, proxy or any antivirus software on your computer? If so, can you please try to temporarily disable these security elements and check if the issue persists?
I’m running Kaspersky Internet Security. I had already set the Mail Anti-virus to scan incoming messages only to see if that made any difference. I have now disabled Kaspersky and tried to send again but get the same error message.
Hi again, can you please try to update your eM Client to this release and check if the issue persists, http://www.emclient.com/dist/v6.0.21899/setup.msi , you should be also able to re-enable the OAB synchronization using this release?
Hi again, sorry to see this, can you please navigate to Tools > Settings > Advanced and enable Exchange Web Services logging for the problematic account?
Save the settings
Restart the application
Replicate the issue
Once the issue reoccurs and one of your messages are not send from the Exchange account, please navigate back to the advanced settings window and submit the logs to my email, [email protected] with a reference link to this forum topic?
