Running GW 2014 R2 on SLES 11sp3

I want to run some maintenance to expire/remove sent mail that is older than 3 months from various mailboxes. Previously, you could select various users and then select Maintenance, Sent Items and "click click" all done. Now, select Post Office, Users, Maintenance, Mailbox/Library Maintenance, then under Actions only Analyze/FixDatabases can be selected.

Any ideas, suggestions etc will be appreciated.
