Public Folder Deletion Settings


We are running Exchange 2007 SP1. On our Public Folder database, I notice there is a setting for "Keep Deleted Items for xx days".

Currently, it is at the default of 7.

I am thinking of increasing it to 20. However - am curious to know what would happen if I had it at 20 and then changed it back to 7 again (e.g. if I noticed that the space was decreasing).

Will this affect the live public folders at all or just the area of the mailbox store where the deleted items are kept? And - out of interest - where exactly are the deleted items kept for x days?

They are kept in the dumpster and no you won't notice any size decrease in the database since the database file doesn't decrease in size unless you perform an offline defrag.

however if it was 20 and you reduce it to 7 at the next maintenance window the "unneeded" items will be cleared.

Thanks - when you say Dumpster, I assume that is part of the EDB database for that store?
yes it is located physically inside the database

thanks (and last question :-) ) - by the above, I mean you mean the nightly online database maintenance that occurs, i.e. allocation of white space?
yes, in the event log the next day you should notice you have more "white space" in your database
