gSyncing: Keep Outlook and Your Google Account in Step
gSyncing is a $34.99-a-year Windows program that synchronizes Microsoft Outlook calendars, contacts and tasks with a Google account, one-way or two-way. If you run desktop Outlook at work and Google Calendar on your phone, it's the bridge between them.
The trouble it fixes is the appointment you add on your phone that Outlook never hears about. Classic desktop Outlook has no built-in two-way sync with a Google calendar, so gSyncing sits in the system tray and copies the changes between them on a schedule.

- What we checked: installer gsyncing_setup.exe, file version 1.1.74 (9.05 MB), digitally signed by Buildway Technology LP, downloaded from the vendor on November 9, 2026; order page price $34.99, marked auto-renewal, on November 9, 2026. We didn't run a sync against a Google account.
Before you buy: back up, and update
In August 2025 the vendor released version 1.1.70 as a critical update for sync errors that could cause accidental data deletion in Outlook. That's fixed, and the current build is newer, but two-way sync tools can delete as well as copy. Back up your Outlook data file before the first run, and leave deletion sync off until you've watched a few cycles.

Overview
gSyncing comes from the team behind SYNCING.NET and is sold separately from it. Where SYNCING.NET links PCs to each other, gSyncing links one Outlook profile to a Google account. Your phone then gets the Outlook data through its normal Google sync, whether it's Android or iOS.
You sign in to Google through its own authorization screen and set up mappings: this Outlook calendar to that Google calendar, this contacts folder to that contact group. Each mapping has its own direction. gSyncing uses Google's current API platform, and its latest build is from May 2026.
Features
A direction for each folder
gSyncing lets you set each mapping to two-way merge, Outlook to Google only, or Google to Outlook only. You can keep a work calendar two-way and push contacts to Google one-way, for instance.
Several calendars and shared accounts
gSyncing can sync multiple calendars and works with shared Google calendars and contacts, so a small team can use a common Google calendar from Outlook. You can pick any Outlook profile and Google account.
Automatic on a timer
gSyncing can run on a schedule from every 5 minutes to every 24 hours, or only when you click Sync from the tray icon. It can also start with Windows.
Duplicate and time zone handling
gSyncing detects duplicate items as it syncs and carries time zones across, so an event booked in another zone keeps its real time. A date filter limits calendar sync to a period you choose, which keeps years of old entries out of Google.
Tasks as well as calendars
gSyncing also carries Outlook tasks to Google, which many calendar-only sync tools leave out.
Benefits
- Stay on Outlook without giving up your phone. No need to move your mail to Gmail just to see your schedule.
- One less thing typed twice. Contacts and appointments only get entered once.
- No extra cloud service. Data moves between your PC and your own Google account.
Real-World Uses
- Outlook at the desk, Android in your pocket. Book on either and both show it.
- A family Google calendar in a work Outlook, so school events appear next to your meetings.
- A team on a shared Google calendar where one member prefers Outlook.
- Contacts kept in Outlook, pushed one-way so the phone always has the latest numbers.
Who It's For, and Who Should Skip It
It's for people who use desktop Outlook on Windows and also rely on a Google account on their phone or in a browser.
Skip it if:
- you want a free option and only need calendars. A free project called Outlook Google Calendar Sync handles Outlook and Google calendars.
- you need mail synced. gSyncing doesn't handle e-mail.
- your company is on Google Workspace. Google's own Workspace Sync for Microsoft Outlook is the tool for that.
- you use a Mac, or the "new Outlook" for Windows. gSyncing is a Windows program for desktop Outlook, and the new Outlook isn't on its list.
Usage Guide
- Back up your Outlook data file.
- Install by running gsyncing_setup.exe (9.05 MB). It contains the 32- and 64-bit versions and picks the one matching your Outlook.
- Authorize Google. In the settings dialog, enter your account and click Authorize, then accept on Google's page.
- Choose your Outlook profile and add mappings for contacts and calendars, with a direction for each.
- Set Auto Sync to an interval, or leave it disabled and use the tray icon.
- Check the application log (View Log in the settings) after the first run, before you rely on it.
- Register your license key before the 14 days end; the Days remaining text shows how long you have.
Where it falls short
- It runs on a timer, not instantly. The shortest automatic interval listed in the guide is 5 minutes, so expect a short lag.
- Old documentation. The quick start guide is from 2015 and still names Outlook 2016 as the newest version; the shop page has the current list.
- Little public feedback. We couldn't find independent reviews of gSyncing, so the trial is how you judge it.
- One computer per license. Outlook on a second PC needs another subscription.
Comparisons
gSyncing vs Google Workspace Sync for Microsoft Outlook
Google's tool is for Workspace accounts and also moves e-mail, using Google as the mail server. gSyncing is a lighter choice that leaves your mail alone and works with an ordinary Google account.
gSyncing vs free Outlook Google Calendar Sync
The free project is built around calendars. gSyncing adds contacts, tasks and vendor e-mail support for $34.99 a year.
Editions and Pricing
gSyncing has one edition: $34.99 per year for one computer, excluding sales tax, as a subscription that renews automatically. That's the order-page price on November 9, 2026.
FAQs
Does gSyncing work with a free Gmail account?
Yes. gSyncing works with a Google account and uses Google's normal sign-in page, so you don't give the password to the program.
Can gSyncing sync more than one Google calendar?
Yes. gSyncing lets you add a separate mapping for each Outlook calendar and Google calendar you want to link.
Does gSyncing support Outlook 64-bit?
Yes. gSyncing's setup contains both 32- and 64-bit versions and installs the one matching your Outlook.
Will gSyncing delete events I remove on my phone?
Only if you enable it. gSyncing has a Synchronize deletions option that passes deletions in either direction, and the guide says it's unavailable in the unregistered version.
Does the PC with gSyncing have to be on for syncing to happen?
Yes. gSyncing runs on the PC with your desktop Outlook profile, so changes only move while that PC is on.
System Requirements
- Windows 11, 10, 8, 7, Vista or XP, 32- or 64-bit
- Desktop Outlook 365, 2021, 2019, 2016, 2013, 2010, 2007 or 2003 (32- or 64-bit)
- A Google account and an internet connection
Conclusion
gSyncing is a sensible $34.99 a year if you live in desktop Outlook but need your calendars, contacts and tasks on a Google-connected phone. The one reason to buy it: two-way sync of all three data types with a separate direction for each folder. The main reason not to: a free tool covers calendars if that is all you need, and there's very little independent feedback, so back up first and use the 14-day trial to confirm it behaves with your data.
