hi!

I have one issue. when i do assign tasks to approval users sending email to outlook - some usres leaves and some not sent. Where not sending in workflow logs like this:   Repeats the last request. The next attempt will be made in less than one minute. Information about the last query: HTTP BadRequest to http: //srv-sps-dev/sites/pr/_vti_bin/client.svc/sp.utilities.utility.SendEmail; identifier relationship: 80cf9c6d-c912-6929-ac57-a9889e61be11; Instance ID: 49c45745-0372-49cc-93a0-ee99debd2bf7.   

Hello,

We usually get this error when the users within the group not having sufficient permissions to send the email. To resolve this update the group settings to "Who can view the membership of the group?" to "Everyone". If you have multiple groups then make sure you change this setting for all groups.

Hope this helps.

Who can view the membership of the group?
