Matching your users in Wonde Google Sync correctly is in some ways your primary objective when using the tool. You'll need to do this in order to have any actions you have denoted to be actioned upon during an MIS sync in the 'Settings' page impact the school's G Suite for Education users.
You can run a bulk user match from Matching >> Match users (incidentally this page looks exactly the same and carries the same function, as the 'Matching' step in the setup wizard and as such, this guide can help you with that section as well.)
After clicking 'Match users' you will be presented with all of the current available matches for profiles from the school's MIS data, they will be listed in order from the strongest match to exceptions at the bottom which will be ignored automatically and not allowed through as a matched user unless you click the 'Ignored' button to say otherwise.
Users are matched from the MIS data obtained by Wonde based upon preferred forename and surname and 100% matches can. be achieved if the email address from the MIS also matches the Google one, Wonde will only be able to match users that are found within the organisational units or sub OUs of those selected in the 'Settings' page. Because of this you may find users with exceptions against their names if (at the bottom of the page) because the Google account previously created before Wonde Google Sync was implemented used the legal forename.
When you are happy to that you have all of the correct matches, click Match.
You can manually match users from the Directory page, by clicking manually assign and selecting th user in the dropdown that opens to the left on the same row. You may seek to do this because you were left with unmatched users that we could not find a possible match for that you have now moved into the correct OU. Should you move users from an OU to an OU Wonde Google Sync has in it's settings, then you will need to refresh the page to have it appear in the 'Manually assign' dropdown.
You can manually assign more than one user and then click 'Save matches' under the Action selected button in the top right-hand corner.
You may want to manually unmatch any users you have matched incorrectly or perhaps just to add them to the 'Ignored users' section (more information can be found about ignored users in the article on Manual actions). This can be achieved by selecting a user with the tick box on the left hand side and going to action selected in the top right-hand corner and selecting Unmatch Google user.
