This my last post and I'm un-subscribing the thread.
I share the instinct to try to find a way to make this new tool work, but I truly think most people on these threads are wasting their time unless they fit a narrow band that fits in to the new watchlist.
The new tool is not as good as the old one, and MS has very little reason to invest the real time and money to do so.
I shifted my daily watch list stuff to Morningstar as that is their business, and they want to upsell you into other services. MS sell MS Money, but there is no real business model for MS on this portfolio manager.
Would encourage any new service you use have import/export from excel to limit future unplanned need to switch.
Other unsolicited advice:
Clearly some of us were overusing the MS Portfolio Manager. It was never meant to be your source of record for tracking basis for doing tax returns.
For true full tracking, I strongly suggest something like Quicken; I am a longtime avid user. (I would note, I do not like Quicken for 'everyday,' up-on-the-screen most of the day-type tracking, as it has every holding in really more detail than I want
to see everyday. MS Portfolio (and now, for me, Morningstar) is for tracking the movements of things I may want to trade in soon, not longterm stuff.
In sum, likely power users should leave MS and find appropriate new tools, and spend no more time trying to make this MS offering work; it is likely not going to work.
Good luck.
