Event ID: 9871 Source: MSExchangeISMailboxStore

There is an online maintenance overlap for database "First Storage Group\Mailbox Database". Please revise the online maintenance schedule.
From a support forum: "I was experiencing this problem and I think that I found the problem. It seems our online maintenance time frame and backup time frame were overlapping, once I changed that, the errors went away."
From a support forum "Event 9871 is logged when the maintenance windows is over for a database, but a transaction is still being processed. Exchange doesn't end the transaction just because it hits the end of the maintenance window, it just logs the 9871. You can safely ignore the error (or extend the maintenance window if you want to avoid the event being logged)."
