Submit documents for thread analysis
To organize documents into threads, you must submit the documents for thread analysis.
The following file types are supported for thread analysis: .msg, .mht, .mhtml, .eml, and .txt.
Thread analysis sorts all submitted documents, but organizes only the documents that share the same subject into threads. Thread analysis also creates document batches, with each batch containing up to 10,000 thread-complete documents. In a thread-complete batch of documents, no threads are split between batches.
Note: If another thread analysis job or a deletion job is processing, wait until the job is finished before you submit additional documents for thread analysis.
