Ok, so my boss got himself an N9, he also manages to do the initial sync with our exchange (2010) server, but after that the dreaded red arrow appears and after that it will not synchronize. This must be a pretty common occurence since quite a few people have already reported this. Hopefully it will be fixed in PR1.1, otherwise the phone will be quite unusable for quite a bit of time if the MfE sync doesn't work. Unless of course the PR1.2 is right around the corner.
Like some others I have the problem that my inbox is not detected. It's IMAP access to a Zimbra 7.0 server. The inbox shows as 'INBOX'. The phone is N950 with Beta2. If you guys need a test account, I can provide you one. Thanks!
