The draw was held on 29 June 2016 at 13:00 in Vienna, Austria. The twelve teams were split in three groups and played a semifinal and final to determine the last participants. Matches were played from 9 to 11 September 2016.[4]
In each group, teams played against each other in a double round-robin format, with home and away matches.
Tiebreakers
In the group stage, teams are ranked according to points (2 points for a win, 1 point for a draw, 0 points for a loss). After completion of the group stage, if two or more teams have scored the same number of points, the ranking will be determined as follows (article 4.3.1, section II of regulations):[6]
Highest number of points in matches between the teams directly involved;
Superior goal difference in matches between the teams directly involved;
Highest number of goals scored in matches between the teams directly involved (or in the away match in case of a two-team tie);
Superior goal difference in all matches of the group;
Highest number of plus goals in all matches of the group;
If the ranking of one of these teams is determined, the above criteria are consecutively followed until the ranking of all teams is determined. If no ranking can be determined, a decision shall be obtained by EHF through drawing of lots.
During the group stage, only criteria 4–5 apply to determine the provisional ranking of teams.
