I regularly get this, and my Outlook will then not open. I have repaired it many times, but only by deleting my MS Office, then re-installing from the original download. This, of course, times a long time. it should not happen.
I have done the full 'clean-up' using the MS tools, when deleting MS Office, but hat can have made no difference, as the crashes still happen. This started a year or so ago, and can occur after just a few days following a re-install, or 2-3 weeks later.
What on earth can I do to get a 'good' MS Outlook?
