Outlook 2016 to Google Calendar & Android Pie
By Darren S.

CompanionLink for Google
This CompanionLink for Google software is working quite well for me. I can add an event to my Android phone calendar (DigiCal) and it updates on my Google Calendar on the web as well as my Outlook 2016 calendar client. And vis-versa. It happens really fast, too. Really the only problem I've seen so far is getting the colors to sync properly. If I add a yellow event on my phone it doesn't show up as yellow in Outlook. Otherwise, really happy with the performance of this solution! And I think the price is very reasonable.
LOVE this sync tool

Tried to use GSSMO. Couldn't get it to work. In other environments where it did work, it would fail to sync and eventually had to be completely restarted. And it only supported calendar syncing. And created it's own Outlook profile. And didn't have many settings.

I've been using CompanionLink's Outlook-Google sync (to G Suite) for two days and I LOVE it. Have already recommended it to a friend, and will be installing it on two more PCs in our environment.

I love the flexibility in the settings. I had some initial dups (which I could have avoided had I set up the settings correctly before kicking it off to run--duh). But it works great. Low overhead. Runs quick once the initial run is finished--which was like 15 minutes.

Have not used support yet. Haven't had to. I was in no way asked for or paid for this testimonial. I'm a fan. This will help several of us use the G Suite calendar or the iPhone calendar app to easily see when our team is available for group meetings...plus will keep contacts in sync. (I have over 1,000 contacts, and thousands of calendar entries.)
Incredible Support! A wonderful surprise.

I was incredibly impressed by CompanionLink's support. I bought their product back in 2014 (four years ago). Last month I replaced my laptop and reinstalled my old 2014 version. It did not work.
I reached out to CompanionLink support (Matt), and he guided me through the steps to get my version working. I was willing to pay for an upgrade to the current version -- as I really depend on this product -- but Matt got my old version working instead. Turned out the issue was Microsoft Outlook and not their product after all.
Some final notes: Tech support was knowledgable -- the problem was complex. The steps were logical (e.g. I was not asked to reboot and reinstall the same product over and over again like other tech support). And best of all - it works now! Awesome. Thank you very much folks!
Love it
