I have a curious problem with N9 MfE client and Zimbra Network Edition 7.2 we are implementing; I can see contents of only HTML-messages, and not plain text messages. One would expect problems other way around, as it has been in the past with Zimbra.

Plain text messages are visible in the inbox, but no preview available and there is just a blank message field when I open one.

At least Android 4.0 does not have this problem, nor does the configuration to our old Exchange 2007. I already tried to switch to only plain text mode on N9 MfE through email settings, so I'm a bit of stumped currently. Tips anyone? Thanks for any help!

EDIT: For anyone looking answer for this, the solution was to download MeMailSettings from Ovi Store, also mentioned in this thread somewhere as well in a thread of its own. Then enable 'Fetch full message's MIME' under MfE-account with it. After this reboot.
Note that already synced emails won't be readable, but all new ones will be. Thanks Sergey and Anton!
