CompanionLink for Outlook

I am so impressed with the OUTSTANDING customer support I have received from CompanionLink, not to mention how pleased I am with how the programs perform seamlessly. Wayland has helped me a few times, and, like the rest of the team, is absolutely AWESOME. Finding a company whose support is this consistently good is hard, not to mention the flawless performance of their programs. I am so happy that I found CompanionLink.

Great for 10+years until I went to iPhone

CompanionLink for Outlook

I just upgraded my CompanionLink -- its been great. But its not the same experience using it with iPhone. The appointment alarms that I came to rely on are now gone because the alarm settings and sounds are poor and barely audiable. All was so perfect with my Android, but I needed the iPhone for car navigation. This works poorly with iPhone, in my opinion. Very disappointed.

CompanionLink just works!

CompanionLink for Outlook

I've used CompanionLink for Outlook for what seems like a decade now and for synchronization of CompanionLink for Android with Outlook running on my Windows PC it's great and has been flawless, even with over 3000 calendar entries and 400 contacts.

Best software I ever purchased.

One of the Best Programs on My Computer.!

CompanionLink for Outlook

CompanionLink is without a doubt one of the most important programs on my computer. It syncs all of my contacts (847 today) and my calendar events (116 today) flawlessly, efforlessly and instantly between Outlook on my desktop and laptop and also as a stand alone on my Android phone. In most cases it does it automatically! And whenever there is a problem (and it's always something I've done) their customer service responds faster than any support I have dealt with and always with the right solutions. You absolutly cannot go wrong with this program.
