I have a 90 day retention storage policy I use for archiving and content indexing normal file systems. We are moving from Notes to Exchange 2013 and have Exchange Compliance Archiving enabled for 7 years. I wanted to also setup content indexing for that archive but I discovered I couldn't create a new SP with content indexing and point it to the search engine as it said the search engine was already used by another SP.
I thought about it and decided to try and use the current 90 day SP and create a copy that is retained for 7 years. My question is, will I be able to content index the data in the 7 year copy after the original 90 days has expired? Is there a better way to accomplish what I am trying to do (utilize the Exchange Compliance Archive with a 7 year retention and be able to content index any job within that time)?
