Sync MS Outlook several jobs between them

MS Exchange?

If you do not want to share, good outlook_social_connector. Once used SIM for integration of home and work Outlook.

The point is that mail, calendar and contacts are maintained on a hotmail.com and in Outlook are fully integrated through this connector. Like in 2010, the office they are seriously finished.

In General maybe this variant, all depends on tasks...

you mean that Google have exchange server.

Correctly say, the best option for Outlook Is a native Exchange server. There are of course all sorts of PSTSync, etc., but as a person serving at the time, this configuration is not recommended, because it is through one place works.
I would, in your case, recommended parking.ru/microsoft/exchange/ and other similar services (have source box, 1GB), it will be cheaper to deploy than the Former (too many require to do if you have a "server not now")

As an option: you can write scripts in VBA that when you add a contact, task,... will write them to a file. And Outlook on other computers, will check this file and create these items.

As a variant of the EVO Collabrator for Outlookthat lets you synchronize contacts, calendars, tasks, not only between MS-Outlook and Gmail, iCloud, Yahoo mail, Mail.ru
