Exception while reading IMAP "Exception: Parse error Input {-2}"

I have seen the read warning icon now and then for a while but today it become more urgent since I cannot send reply to emails anymore. I get a message “Message was not completely downloaded and thus no operations can be performed on it.” and can not send the reply neither save as a draft.

Looking at the IMAP log file it is 31000 rows of successful dealings and then it ends with this Exception (at 10:13:28.166). After that it gets the same exception one more time and ends with “10:13:28.571|010|   AccountBase.ChangeOnlineState : STATE CHANGE TO offline due BrokenConnection”.

Very grateful for help with this.

I’m still affected by this today. I did not have any problems during the whole last week. But today I’m experiencing this error again. The log for today looks the same. Here is the exception part:
