Hello all, I've recently just rebuilt our search indexes across our three MB servers due to their ever increasing size. This is about the second time I have down this in about 10 months. They were up to approx 30GB and after the rebuild are now down to about 1.5GB I've been trying to find if it is recomended to schedule this task, monthly for example, to prevent me from having to run this manually or potentially missing the disk space alerts and running out of space. Secondly, I'm trying to work out if this large growth is "normal" (we're Exchange SP2 BTW) or if it is a side effect of our Symantec Enterprise Vault archiving solution somehow. I look forward to your responses. Thanks.

Hi qsxr, Per my know, rebuilding the Full-Text Index Catalog will not address the disk space issue. The Full-Text Index Catalog rebuild still will fill to the same size as before. It is a only temporary fix for the disk space issue. The correct way to fix this issue is upgrade your Exchange Server 2007 SP2 to SP3. Exchange 2007 SP3 use MSSearch 3.1 which will address the large Catalog folder issue. Other information for you: http://blogs.technet.com/b/exchangesearch/archive/2011/03/22/exchange-2007-content-index-grows-from-50-to-167-of-database-size.aspx So, it is recommended to update the servers for sp3, no need to rebuild it frequently.
