Sending emails to selected groups using Nintex workflow for SharePoint 2010 not fully working

Hi,

do you iterate the groups and send mails or do you send all mails to all groups at once?

Could you add a picture of your workflow to help us understand, what the scenario is?

Best regards

To be honest, I had outside help in making this work, primarily on pulling all the work groups from the list and only emailing those that are selected in the infopath form. 

This is the list.

This is the infopath multi-select list box.

This is the workflow as it pertains to this notification functionality.

Hmm,

so when you use single groups with some users the notifications are sent correctly but if you hit all then no message is sent at all?

You could check in exchange logs if there is any error occuring on that side. To exclude the number of users as a cause you could also try to work with group adresses and let exchange resolve the participants.

Would that be an option for you?

Best regards

The issue is when I send out to all groups, the workflow processes without error but the emails never come.  I can select multiple (but not all) and the email will come, depedent on how many individuals are in each group.  My guess is that it has more to do with how many individual emails are sent as opposed to how groups are selected.

Can you expound on what you mean by working with group addresses?

Thanks.

Sorry for the delay. You can try what happens if you work with active directory groups or SharePoint groups. That might help resolving the single users and help the workflows send a mail to everyone.

So instead of naming all your users in your list, just build groups for every list entry and name only the user group in your list.

Thanks for the reply.  I did as you suggested.  Instead of putting individuals into the people picker, I placed created permissions groups.  I selected 1 list item that had 3 permissions groups in it and initiated the notification workflow, which ran without error, but no emails were sent. 

I then ran the notification workflow on 1 list item selected that had 1 permissions group that contained only 1 individual (me).  The workflow delivered the notification as expected.

Any thoughts or other things I could try to narrow down the issue?

Hmm, that sounds strange. I didn't experience problems like this in my projects so far.

You could check your mail server if there is any mail throttle defined that prevents your SharePoint server to send more than a specific amount of mails per period.

If there is no such throtteling configured I'd suggest you reach out to Nintex support to work this out with them.

Best regards
