Error: The attachment cannot be downloaded

Very recently (and not having encountered this problem before) I have been unable to download *some* attachments. I cannot open or save or forward them. I get the error message: The attachment cannot be downloaded

Hello Andy, sorry to see this, what version of eM Client are you currently using on your computer, can you please check the exact release number in Help > About? What mail service are you using with eM Client?

Are you using any Rules that would move the received item with included attachment to a specified folder?

Same problem 6.0.22344.0 MS Exchange mail. Can’t download some *.zip file, some docx files.
In first mail i can’t download file *.zip, but in second mail i can download. I don’t understand difference.

Hello again Ivan, Are you using any Rules that would move the received message with included attachment to a another folder?

i have rules for some messages, but 2 messages come from 1 person and wasn’t move to any folder. 1 of them openes, another - not.

Hello again Ivan, can you please navigate to Tools > Settings > Advanced and enable Exchange Web Services logging for the problematic account,

  1. Save the settings
  2. Restart the application
  3. Replicate the issue
    Once the error reoccurs, please go back to the advanced settings window and submit the logging data to us for more information about the error.
    Use the “Send logs” button to submit the logs to us and add me as a copy to the message, and please include a reference (URL) link to this forum topic.

Thank you.

Hi Paul

So the version I am using is 6.0.22344.0 and I’m not using andy rules that would move the received message with included attachment to a another folder.
I’ve sent you my log files for the problem.


Hi Paul,
I’m also using Version 6.0.22344. The problem occurs with an Exchange account only. No rules here.
Do you want me to send you my log files?
Thanks, Nosrednab

P.S. I’m not sure if this is related, but I also get a “Can’t process message” error when I attempt to forward an e-mail from which I can’t download the attachment. The error says, “Message was not completely downloaded and thus no operations can be performed on it.”

Hi Paul,

I am also receiving the same issue, its only just started. i have also sent you the log details.

Also could it could be specifically effecting emails that i flag.

I checked with my Exchange service provider and they claim they haven’t performed any updates this calendar year.

Hello are you having issues with items in your inbox or only items in other subfolders of the Exchange account?

I’m only having problems with items in my inbox for my Exchange account.



Thank you, the question was mostly set to Jarry as he managed to find a link between flagged emails, I wanted to follow-up with that. Are you able to confirm this?

Just checking in–I also am having the same issue. Started a week or two ago with Exchange attachments. Using version 6.0.22344.

I have the same issue with my Microsoft exchange online account and version 6.0.22344.

Hello again, can you please try to perform folder repair on the mail folder where you’ve received the message? For example if the message with attached file is located in your Inbox try to repair your inbox folder.

To repair the folder, right click the folder in the left pane and select Properties > Repair and click on the “Repair” button, this will completely resynchronize the folder with the server, e.g. removing the items locally and downloading what’s available on the server.

Please check if the issue persists and let me know.

Thank you and sorry for the inconvenience.

Hallo, repairing the folders work. THX.
