We have the ability within Nintex on prem to add the "Check in Comment" item property to the body of an email. In O365 we have been unable to find it in the "Insert Reference" list and Nintex support have confirmed this is expected behaviour.
Has anyone done this before or know how to retrieve the value?
You can use action "Office 365 Query List", make a filter on the ID of your item, and, select the "Check In Comment" field
Use the internal name of the field, normaly it's "_CheckinComment"
