What's synchronized between Outlook and G Suite?

G Suite Sync for Microsoft Outlook

Email, calendar, and contact data are regularly synchronized between your Google Account and Microsoft Outlook with G Suite Sync for Microsoft Outlook (GSSMO).

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