Hello all-

We have an Exchange 2007 server that we are receiving notifications in the event log that "There is an online maintenance overlap" for our mailbox database.  Checking the maintenance schedule via the management console GUI on this database shows the correct schedule in which we want online maintenance to run.  Checking the maintenance schedule via the management shell shows that there are indeed multiple schedules for this database.  After much searching online I can't seem to find how I can remove a maintenance schedule.  Any help with a shell command or other means to remove the maintenance schedule would be appreciated.  See image for example of multiple schedules we are seeing.  

Multiple Online maintenance schedules for mailbox database
Thanks,

Daniel

You are using Exchange 2007 so you have your Mailbox Database and you also have storage groups as well. when you do Get-MailboxDatabase | fl identity, maintenanceSchedule

you will notice that these are different schedules for each StorageGroup on the database, which is why you see multiple values. If you add "identity" as i have done above you should see that they are different and not the same.

That being said, if you want to change the schedule for a database maintenance use the syntax below...

Set-MailboxDatabase -Identity "Server01\MailboxDatabase1" -MaintenanceSchedule "Sun.2:00-Sun.3:00","Wed.2:00-Wed.3:00"

Open in new window


You can also do this from the EMC. For more details see the link below...

Thanks Will.  Altering the shell command as you suggested did show one schedule for Storage Group\Mailbox Database and one for Recovery Storage Group\Mailbox Database.  I attempted to edit the Recovery Storage Group\Mailbox Database's schedule but it's telling me that I can't for a recovery database.  Just want to verify that is true?  

Thanks,

Daniel

That is correct. You cannot change this property. Your error message should have shown you something like below...

Powershell Error
"The Property that you specified cannot be changed on a recovery mailbox database"
Specified Property: Maintenance Schedule

That's the one.  I will modify the Storage Group\Mailbox Database schedule to not overlap with the recovery group schedule.  Thanks for your help.
