You first need 110% disk space to perform offline defrag and reclaim whitespace. Next you need downtime to perform offline defrag. Depending on the DB size, it can takes several hours to few days to complete. Normally, 4GB per hour Exchange can perform offline defrag.

If you have 110% disk space and users are ready for downtime, you can go head and perform it.

If not, then creating new db and moving mailbox to new db. Then deleting current db and recreate it again. If this DB is part of DAG, avoid offline defrag.
