Important: Once you connect your Gmail account to Outlook, you may receive a warning message in your Gmail inbox telling you that a new logon from Internet Explorer was detected. This is expected behavior. Review collected by and hosted on G2.com.

It is very satisfactory to unify the mail trays, especially if the company handles several emails. Unify contacts is an excellent tool.

Really, an incredible way to synchronize Outlook and Google without having to plug the phone to the computer, the best thing is that no matter where you are, automatic synchronization is the best part. So far it has been great, I have not had problems.

I have used O4G to synchronize my calendar and outlook contacts to my Google account, fulfilling what was promised through automatic synchronizations. I do not have to worry about the differences between my accounts, since I can always trust this application, which can work in the background. I like that my cellphone silences itself when I'm on a date. Review collected by and hosted on G2.com.

Sometimes I received error messages due to microsoft updates, although this I have not received it very often is annoying, however, the customer support that is available is quite good and they have always solved the failures. I think that O4G can also be presented for languages other than English and be much more intuitive and easy to use when you start using the add on. Review collected by and hosted on G2.com.

I like the event log that's easy to track changes. It worked pretty well connecting into Outlook and I didn't see a lag of any kind. The dashboard was easy to understand and use. The initial calendar, appointments synced up pretty smoothly. That's about it when it comes to the positives Review collected by and hosted on G2.com.

I've had issues with ongoing calendar items continuing to sync after the fact as sometimes it fails altogether. My recurring events/appointments are all screwed up and whenever I reach out to tech support I don't get any response. The ongoing pain that this product has given me has led me to write this review.

Easy way to sync google calendar and contacts with outlook. If you have multiple emails in your organization, or you just like using outlook instead of gmail, it's the best solution. Most others are too expensive or not fully featured; some are even both. Review collected by and hosted on G2.com.

The UI is clunky and not very intuitive. Setting up the sync can be confusing, but overall isn't the worst. Just takes some tweaking. Review collected by and hosted on G2.com.

Worked great for awhile. When it did, I could receive outlook notices via gmail which made checking my schedule and responding to work emails much easier, especially due to the issues with Outlook on phone. Review collected by and hosted on G2.com.

After several weeks of use, there were issues with syncing gmail and outlook. Sometimes it would resolve, but it got worse and worse - especially with updates. No longer using, but will use again once the kinks have been fixed in terms of the gmail-outlook syncing. Review collected by and hosted on G2.com.
