IMAP communication errors

I have earlier in an Idea post mentioned communication errors that I have not come across with Thunderbird or Outlook 2010.

The listed accounts below are all Imap accounts using SSL on port 993. Regulary error exclamation icons appear next to the account name.

The error icons disappear by ordering a sync.


send us your logs please: go to menu Tools->Settings->Advanced->Logging and check “IMAP” under the problematic account. Then restart eM Client,
try to simulate the issue and send us (with reference to this topic) the logs using the same logging settings window. Thank you.

I have sent you the logs.

Thank you.

I to have this problem… No harm but rather irritating. It can go a whole day without any errors and then suddenly I get bursts of them for an hour or two before it gets quiet again…

Hi, what email provider do you use? Do you use IMAP protocol as well? Do you see any error message when this happens?

Anyway these “!” means that account is not connected to server. Do you sit behind proxy or firewall?


I use a bunch of different ones, two are gmail, one is iCloud and then there are two unknown. One of these uses squirrelmail as web mail client… All of the use IMAP as protocol.

Im behind a firewall. The one built into the Netgear router but all ports used are open. No proxy…

The connections works then suddenly I get an error dialogue but as soon as I push the red exclamation mark everything works. I have even managed to push it within a second after the error…

So I don’t think it is the firewall, nor do I think it’s the network. It must be connected to imap and the way the client handles that protocol.

I used to use Outlook and it “never” failed against the same accounts… Same router, same network, same computer…

The error message is in swedish but the meaning of it is that IMAP has failed, probably due to network failure or that the server is dead… But the server response immediately afterwards and no errors in the network what I can see.


Could you tell me what is in that error message in English, if it is okay for you to switch it into English for a while.
