I have deployed 16 databases in 16 SGs on an Exchange 2007 Mailbox Server, I am pretty confused here whether i should keep the online maintenance window for all my databases same or should i change it on every database?I know that it is recommended that it should run everyday on the databases however pretty confused whether it should run complete running on every 14th day on each database keeping in mind that the databases are set to run the defrag on the alternate time or same time?Please advice or comment

I found the answer, it is recommended that it should be configured atleast with the interval of 15 mins between each databasehttp://technet.microsoft.com/en-us/library/aa995795(EXCHG.80).aspx
