1 Nov 2012: The server responded: MBN00000007 BAD Could not parse command

Thursday 1 November 2012: in the last 48 hours it has become apparent that the behaviour of some of Google’s Gmail servers has changed without any warning. As a consequence of this, users are now experiencing errors saying “The server has responded with negative reply. The server responded: MBN00000007 BAD Could not parse command.”

We have produced a fix for this problem in today’s software release. If you’re not prompted to upgrade automatically, please download the new installer from:


For enterprise users, you do not need to produce a new installation package. Simply take your existing “Settings.afx” file and pair it with the new MSI installer from the link above to perform your upgrade.

We apologise for the inconvenience to all our users, though we wish to point out that we were given no forewarning of any changes by Google.
