SharePoint 2016 on prem running SP 2010 SPD workflow - Multiple emails

Sherazad Ahmed 371 Reputation points


I have an SP 2016 farm running some 2010 SPD workflows. I am having issues with the same email going our multiple times to the same contractor at the same time on the same day. I can see this happening in the ULS logs.

I see entries like this;

"No match in user info list. Input : <customer email>"

Followed by:

"Beginning attempt 1 to send mail to recipients"

The customer email is obviously external so they would not exist on the user info list. All the emails go out successfully, but I am trying to figure out why it's being sent more than 1 time.

    Hi @Sherazad Ahmed ,

    The message you received, “No match in user info list. Input : <customer email>”, is a system-generated error message that indicates that the email address you entered is not recognized by the system.

    The second message, “Beginning attempt 1 to send mail to recipients”, is a notification message that indicates that the system is attempting to send an email to the specified recipient(s) .

    I wasn't able to reproduce your situation, I checked internal and external sources and couldn't find a reason for only one failure. And as per your description it seems that All the emails go out successfully, I guess the one that failed could be due to poor network or something else.

    This may be an occasional incident, don't worry. Feel free to let us know next time this happens again.
