What's synchronized between Outlook and G Suite?

G Suite Sync for Microsoft Outlook

Email, calendar events, and contacts are regularly synchronized between your Google Account and Microsoft^® Outlook^® with G Suite Sync for Microsoft Outlook (GSSMO).

Some types of data aren’t synchronized. And, some features in Outlook function differently if you use GSSMO. Data might look a little different in certain G Suite tools, such as Gmail.
