We have a business consultant that needs to run "collect feedback" workflow for ~16 users.

It seems there is a character limit in the first Assign To field.

Is there a limit to the number of participants Assign To a collect feedback workflow? If so, what is the limit?

1 Answer 1


The Assign To field is considered a People and Group field, and Unfortunately, Microsoft didn't mention exactly what's the limit of users per People and Group field. it just mentioned the size per column that is 10 bytes, where the sum of all columns in a SharePoint list cannot exceed 8,000 bytes

For more details check Software boundaries and limits for SharePoint 2013 - Column

Regarding your scenario, I tried to add more than 16 users in Assign To field on my side that worked properly, (By the way, you can Everyone in this field!)

But It is recommended to create a group and add these users to it, and at Assign To field, set this group instead of adding 16 users one by one.
