Hi. I'm going further in my tests with OLK 2013 and sadly I've a new issue: with just one account, the one using it more extensively, the same mail is displayed two or three times. For what I could understand this happens only on Outlook. The user also has other devices synced (iPad) with no problems, and the ZWC shows only one message (no duplicates).
I thought this could be related to the "Too many SOAP sessions" error, but looking at the log there is no such message for that user (but for others).

I checked release notes for duplicate messages and the only reference I could find is about the RowCmp fix. My z-push is patched, but it could be that I initially configured the account with the original function, and changed it later on. Can this be an issue?

Anyone has suggestion? Maybe I should issue a resync?
thanks
