What I would like to know is when Microsoft are going to address long-standing bugs like this one:

Not interested in Cloud. Not interested in Exchange 2013 or later. Not even interested in Exchange 2010. Not interested in Office 365. Not interested in Office 2013. Not even interested in Office 2010.
Still running Exchange 2007 and Office 2007 and will be until I see some evidence that Microsoft are fixing bugs that have been reported Over and Over and Over again. Wake up guys. Speak to your management. Customers like me are NOT happy with stuff like this ... and I am telling my management "We are NOT buying any more Microsoft products until I see evidence that they are fixing such widely-reported bugs".
