If there is a need to stop Incremental Crawling (crawling new items as they are added or updated), clicking the Enable/Disable flag will turn it off. This will not delete any previously indexed content or prevent that content from being searched.
Any Content Sources that have Collabspace disabled will be listed in the Status column.
Note that if the connector is in the middle of crawling when it is disabled, the crawl will immediately stop. Any items that were not crawled will not be crawled.
