In theory the N900 should sync through MfE. In practice I have found it completely unreliable. It fails consistently. I have redone my settings following various guidelines that propose to fix Google synce but to no avail. Yesterday I tried Nuevasync. It has been working perfectly. Now MfE syncs mail contacts and calendar with push just the way MfE worked on my E71. I am not sure what the problem with the implementation of MfE on the N900 is but if you want your Google accounts synced through MfE then this is the best solution I have been able to find. I did several test back and forth adding and deleteing events on my phone and on Google and it pushed changes within seconds. I have been frustrated with Google sync since I got the N900 three months ago. Ideally MfE on the N900 should just work with Google but until that time this works splendidly.
