Important Notes:

• Rebuilding a search index might take several hours, depending on the number of emails stored in the respective archive store.
• Rebuilding a search index impacts performance on the server, since this is a processor and hard disk intensive operation. It is recommended that this procedure is undertaken during off-peak hours, for example, after office hours.
• Always rebuild one index at a time for the reasons listed above.
