eM Client could not sync folders via davmail and exchange

I tried to use eM Client in combination with davmail to manage my company-email witch is hostet on an exchange server. Connection an downloading the “Inbox” is fine, but when I try to download big emails (7 MB) or sync complete Folders (>1000 Mails), the connection will faile after a while. This could not be an issue of davmail, it works fine with Thunderbird. Only the combination eM Client and Davmail failes.

I know: switching off the “offline-feature” is a work around, but when I want do use eM Client as my standard client, I have to have total access to all my emails, not only the inbox!

I have build some logfiles. Where should I mail these files?

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.
