Pros: Once you get the correct activation link, everything works as it should. Having all the Office products is really nice.

Cons: The link provided with my purchase wasn't accepting the key code provided by Newegg.

Other Thoughts: After multiple calls to Microsoft support we finally figured out that the link provided was for a different version or type of Office. The link that works is www.office.com/setup365.
Once we used that link, everything worked as you would expect.

Pros: price and latest version

Cons: the process to get this running was to long and drawn out. The required website should be in bold letters, You must right down all the website, id and password information. The really long log in can't be changed. When you talk to Microsoft the person you reach doesn't know or care that you are in the the wrong telephone que. When you have those three items it works!

Pros: Got the product code via email fast.

Cons: Product code didn't work. Wasted over an hour trying to contact Microsoft support. Gave up, and ran to a local retailer and purchased a physical copy.

Pros: None

Cons: Cannot activate product even with hours on the phone with MS tech. Constant run around & wasted time. Cannot get refund due to download software agreement. Save yourself the headaches. Not worth the time.

Other Thoughts: This is the second time I have been burned trying to recommend this product for my small business customers.
I will NEVER try this product again.

Pros: It's great if you've never heard of openoffice or libreoffice, otherwise offers little value aside from baked templates for various things. Again, most of this can be done with online resources and open-source templates available for openoffice or libreoffice.

Cons: Where to start... Using Office 365 on a windows system works well enough, but on anything else is a disaster of a service. Any web-based components do not work under chrome/chromium, simply coughing up server errors. If you thought the ribbon concept was confusing, wait until you see this.

Furthermore, the services hosted by microsoft inside of their "azure" cloud are terrible. Chronically laggy, buggy, non-responsive. The services are barely usable with a Mac, and utterly unusable under Linux (by design, they hate competition for a failing OS).

If you're using this for anything but working with their hosted email, you might as well do yourself a favor and stick with older versions of office, or just realize there are open-source solutions that do the same functionality, in many ways much better, for free.

Other Thoughts: My company migrated to Office365 because of close microsoft ties for hosting their os we do, and essentially left all non-microsoft users to fend for themselves (I use linux). I found out quickly that all their hosted services are extremely unfriendly toward anything non-microsoft, on purpose I'm certain. Their support for service and products were flat out refused on anything but microsoft os or clients, or which I simply refuse to run as a host OS.

Heaven forbid you move to their hosted exchange solution with it, as their cloud services are so slow and unresponsive, it causes 3rd party clients, even ios and android via activesync to freak out. I watched a tablet syncing with their service take a minute per email to download, let alone trying to use any of the hosted word/excel products with it.

Truly a mess, and exactly why Ballmer was forced to step down and be replaced. 15 years too late unfortunately.
