Running list of useful GAM commands
If you admin Google Workspaces and don’t GAM, you should GAM – get it from here. The big command reference list is here, but these are the specific ones I use most often.

gam user user1@domain.com delegate to user2@domain.com

gam user user1@domain.com sendas user2@domain.com "Friendly Name" gam user user1@domain.com show sendas

gam user user@domain.com show vacation
Set a user’s vacation / out of office status and message
gam user user@domain.com vacation on subject "The reply subject" message "The reply message"

gam print groups name members owners managers > the_name_of_the_output_file.csv
This creates a row in the csv for each member

gam all users add drivefile drivefilename "
Give someone access a folder on a user’s Drive

Add an address to a user’s contacts. Handy for creating exceptions for the built-in username spoofing protection.
gam user <my_user@domain.com> create contact email personal <contact@domain.com> primary
gam all users create contact email personal <contact@domain.com> primary
