I have enabled logging and turn on IMAP debugging.
Trying to log in via mobile client doesn't generate ANYTHING in the IMAP log files. As a test, I also ran outlook with IMAP client and this DID generate an IMAP log file in ~/tmp. But the mobile client did not. Nor did it add anything to the outlook-generated IMAP log file.
In terms of the logging - although a very small number of messages do appear in the scalix-swa.log file when I first connect to SWA (entries about the locale?) nothing appears when I try the mobile client login. I had set the logging level to INFO.
Any more ideas?
