Microsoft has belatedly responded to criticisms of its most recent cumulative update for Outlook 2007 — in particular, the issue (raised by Lifehacker a few weeks ago) of the "don't install this unless you have to" warning on the update download page and associated emails. In a post on the Outlook team blog, Microsoft says it won't be using that as a shield to hide behind if things go wrong:
This is a fully endorsed product from Microsoft that you should feel confident about installing.
However reassuring you find that, the post also points out that some users have been experiencing delays of an hour or more while Microsoft rebuilds their PST file as a result of the new update. As such, I'll be holding off until I can spare a few hours for their fix.
