Where can you check for documents excluded from your email threading set?

The Show Document Errors button is the correct choice for checking documents that have been excluded from your email threading set. When managing email threads, it's important to understand which documents are included and which are not. The Show Document Errors feature specifically identifies any issues that might have led to documents being excluded from the email threading set, such as metadata problems or compatibility issues.

Using the Email Threading summary would provide an overview of the threading results and the documents that are included in the threads, but it would not highlight exclusions. The Field Tree Browser is more helpful for navigating and understanding the data fields associated with documents rather than pinpointing specific exclusions. Likewise, the Saved Searches Browser is focused on managing predefined search queries rather than on troubleshooting threading issues.
