Currently I have a trigger which auto-follows specific groups in our organization when a new user is brought onboard. The auto-follow trigger feature works great! However, we have quite a few groups we would like these users to follow, based on various departments, which means that the user will get emails for each of the groups they are added to. I would like to turn off email notifications during this process.

To do this, I found Database.DMLOptions.triggerUserEmail. This seems to be exactly what I am looking for, however the sending of th email persists. Below is the short function which is called by the trigger. As you can see, I tried adding the options to both the cand ChatterGroupMember object and to the database.insert. Using only one of these email header option sections also continues to send the email - as if it is being completely ignored.

Any assistance would be greatly appreciated.

/* Trigger */

    trigger User_AI on User(after insert, after update) {
        if(chatterAutoFollow.preventRecursive()) {

        // Run this only on insert
        if(Trigger.isInsert == true || Trigger.isUpdate == true) {

             * Now let's add the users in the list who have their flag set for FLVSConnect groups

            // Get the users with their flag set
            Set<Id> followGroups = new Set<Id>();
            Set<Id> disableAllFeedsEmail = new Set<Id>();
            List<User> newUsersForGroups = [select Id, UserPreferencesDisableAllFeedsEmail from User 
                                    where Id in :trigger.newMap.keySet() 
                                      and Follow_FLVS_Connect_Groups_Now__c = true];

            // Since we are using a future method, let's put the users into the follow group set
            for(User newUser : newUsersForGroups) {
                if(newUser.UserPreferencesDisableAllFeedsEmail == true) {

            // now let's run the follow, but only if we have users that need to follow.
            if(followGroups.size() > 0) {

/**** * Class called by the trigger: */

        public static void AddToGroups(Set<Id> userIds)

Just did this for one of my orgs..

You need to update the users records setting UserPreferencesDisableAllFeedsEmail before adding them to the group

    list<User> inactiveNotificationUsers = new list<User>();
    set<Id> notificationUsers = new set<Id>();

    for (User u : [ SELECT ID
                           , UserPreferencesDisableAllFeedsEmail
                    FROM USER
                    WHERE UserPreferencesDisableAllFeedsEmail = false
                    AND ID IN:  YouUserIDs]  )
        User ut = new User();
        ut.UserPreferencesDisableAllFeedsEmail = true;
        ut.Id = u.Id;

Then create the collaborationGroupMember for the users..

          CollaborationGroupMember groupMembership = new CollaborationGroupMember(
                    CollaborationGroupId = YourGroup.Id
                    , CollaborationRole = 'Standard'
                    , NotificationFrequency = 'D'
                    , MemberId = userId  );

Then you need to update the user and create the membership..

            update inactiveNotificationUsers;

        if( !groupMemberships.isEmpty() )
            insert groupMemberships; 

        resetEmailNotification( notificationUsers );

The final trick here is to reset the user's email notification.. You cannot do this during the same transaction so you need to call an @future method to get the email not fire.

public static void resetEmailNotification( set<Id> userIds )
    system.debug('userIds: ' + userIds);

    list<User> notificationUsers = new list<User>();

    for (User u : [ SELECT ID
                           , UserPreferencesDisableAllFeedsEmail
                    FROM USER
                    WHERE ID IN: userIds ]  )
        User ut = new User();
        ut.UserPreferencesDisableAllFeedsEmail = false;
        ut.Id = u.Id;

        update notificationUsers;
  • Unfortunately this is already being done in the heart of my trigger, and is actually the model that I used to create the trigger code. In addition to the above, I have also added a check for recursive, so that the code is not run again during the update of the user. If the recursive check is not added, the trigger is put into an infinite loop as this is an update or insert trigger. – Ilene Jones Oct 28 '14 at 20:14
  • order of operations.. Your user update is not committed to database during after insert trigger. Don't set the UserPreferencesDisableAllFeedsEmail via a trigger and try to create a CollaborationGroupMember during same transaction. Do an user update as shown in example code. Yes you should be preventing recursion. salesforce.com/us/developer/docs/apexcode/Content/… – Benjamin Pirih Oct 28 '14 at 22:04
