I'm doing the one month free trial of Office 365 on my Mac. I thought I'd try Outlook as an alternative to Apple Mail.

My email accounts are via Gmail using IMAP.

But the very first thing I noticed was that out of all the mail clients I've tested, only Outlook seems unable to sync the red flags I've marked many messages with. They do sync in Gmail, in Apple Mail, on my iPhone, on my iPad, with the new Airmail OS X app and even Thunderbird. Only in Outlook do they not sync.

Is there a way to make them sync?

Thanks,
