Also:
"need-based"
"up-to-date"
(Hyphenation is key.)

"System Outages for POLARIS Landscape for weekend and next week" is a sentence fragment. Is it supposed to be a title of some sort? If so, it's fine, but if not, then you just can't do that.
Anyway, it should be "for this weekend"
Monday morning: "morning" does not need to be capitalised unless it is part of a title or heading, in which case "evening" should be capitalised as well. Same goes with the rest of the stuff: capitalise it only if it's part of a heading.

"Next week Outages" should be either "Outages Next Week" or "Next Week's Outages" (I'm assuming that it's a heading; don't capitalise it if it's not).

If you have any questions, please contact the Landscape team (Tom Sullivan, Dan Voetberg, and Raj Kumar).
