Thank you for reporting this issue. We confirm the problem with iTunes syncing for iPhone 6, and we are already working on its resolving. You can configure iTunes plugin to sync folder with music from iPhone to iTunes playlist on Mac, but not the other way round. We will try to address it as soon as possible and release an update for SyncMate.
As for the sync with Outlook for Mac, I regret to inform you, but since the release of Mac OS 10.9, synchronization of Outlook for Mac data is no longer possible. Both, Outlook and SyncMate 4, used Mac OS sync service driver, for synchronization process. It has been excluded by Apple, from the operating system in Mavericks.
In SyncMate 5, we have included our own developed driver, to support the OS X Mavericks and higher. But, in order for Outlook to sync properly, Microsoft should include similar driver into their software on their own.
That is why Outlook synchronization is not currently possible under OS X Mavericks and Yosemite, and it can not be handled by SyncMate.
