Hello, I am trying to set an event for a group. Group is configured as: <group> <uid>group01</uid> <guid>group01</guid> <password>group01</password> <name>Group 01</name> <members> <member type="users">gauravj</member> <member type="users">esteffl</member> </members> </group> Event was created by 'gauravj' and was created in its calendar resource However server did not expand the group and did not create for 'eteffl' I also tried to set 'EXPAND = 1' on event as seen below but it did not help. How can I get server expand the group?
