I ditched Outlook years ago in favor of Thunderbird.

 Anything weird or funky to take note of?
 
Personally, I can't wait to ditch the 2007 Outlook component!  I've had issues for months with it...  The rest of the applications have been fine so I'm hoping nothing gets messed up.

I think it's a pretty safe bet that something will be weird and/or funky. If not, it'll be the very first version ever that didn't.
 
Not only have I used every stinkin' version from the dawn of time going back to before they called it "Office", I have to support them all in my own software (which talks to Word, Outlook and Excel). What a frickin' PIA it's been! They don't just randomly reconfigure the UI, they mess with stuff under the hood, too. My code is full of "if version X do this, else do that" statements, the result of 20 years chasing a moving target.
 
For my own use, I stopped using Outlook long ago. Thunderbird is my email client. It's had its growing pains - the first version I tried was unusable - but it's pretty full-featured and stable now.

gave up on MS long ago.
 
been using "Open Office" for long time now.....

OpenOffice (StarOffice) or LibreOffice (a fork of OpenOffice) are excellent alternatives.  I have a preference for Libre, but you can't go wrong either way compared to MS

And Thunderbird for email & nntp ...

I've been on Office 365 v2016 for I-don't-know-how-long (updated/upgraded in the background). No problems.
 
In spite of the old (and accurate) admonition to "Look out for Outlook!", I've stayed on it after leaving the corporate world (or, more precisely, after the corporate world told me to take a hike). MS have dumbed down the calendar and to-do sections of Outlook so much as to make them unusable.
 
The problem is, I have SO many saved emails from so many years tied up in an Outlook .PST file that switching to any other email client is a non-starter. I tried all of the existing clients and all of the existing .PST conversion/import utilities. All failures.
 
So, I use Outlook for email and Google for calendar and to-do (Google, because I use the Chrome browser, and have an Android phone and tablet, for which excellent calendar and to-do apps are available (aCalendar+ and SplenDO, respectively)).
 
I have gotten as far away from Mozilla as possible. I used Firefox for quite some time, but got totally frustrated with its extensions borking every time Firefox updated. Once Chrome stabilized, I was gone. Once off Firefox, using Thunderbird didn't make much sense. And I could never get the Mozilla's calendaring to work well for me.
 
At least MS have given us a couple of UI skin choices (Dark Gray and Colorful (white, with the old (original) color window headers)). That all-white look was AWFUL.
 
I switched to the subscription mode ($70/yr) and have been happy with it.
 
I've been as big of an MS basher as anyone, but I have to admit that once I got used to the Ribbon interface, I have really gotten to like it.

I've never found a use for using an email client. I've never found the need to have emails saved to a hard drive. I use Gmail for everything. I have my business email linked to Google Apps so that I can use the Gmail interface for it. I use email pretty heavily and have yet to find something that Outlook or Thunderbird does that Gmail can't do either by itself or with an extension.

stuck on 2013...It's OK.  I also have Libre Office at home and so far I have not found any incompatible documents.
I am used to the ribbon of Office, so the Libre Office "ribbon" takes a little getting used to, but the price is right!
 

For mail, I use a mix of Outlook and Thunderbird. Outlook mainly for imap accounts like Hotmail/Live and Gmail and Thunderbird for my pop accounts from my ISP.
 
Of the other options out there, I've used OpenOffice and Google Drive.
 
Drive is nice for sharing and collaborating but I found that for complex work, it's not so good and their spreadsheet "app?" is sluggish when you have larger documents.
 
OpenOffice is great if you want a free option but it lacks a lot of features and feels clunky overall. We use to do a lot of Powerpoint/Presentation work with it and the transitions in it were terrible.
 
MS has really been stepping up their game with Office 365/2016. I just hope they don't bugger it up like they have been some other stuff lately (Windows Phone for example). They do need to make document sharing a bit easier. Hotmail/Live/Outlook.com needs a complete overhaul that is appealing to modern users. I rarely use the web interface though. I should spend some more time with it and see if it's gotten any better.
 
That's just my take on them.
