It will fall now as the former ceo confirmed that Microsoft is just a participant and not a partner. No one has yet confirmed this news but it surely had a negative impact on the price atleast for now.
For long term hold if Microsoft is indeed a participant that would mean more companies might collaborate with them i have already purchase 100 iota maybe it might be profitable in the future.
Here's the whole story, please research more--getting annoyed at correcting this misinformation over and over and over again.

I want to make it clear: a simple 2min search would show you that the story is complete bullshit.
If you just copy&paste without checking the source/story, you better leave the trading world...
