Hi

I'm  migrating  from  lotus  notes to exchange 2013  unfortunately  when converted  emails  from lotus  to pst  and imported into  exchange  I realized  later  that  a lot of replica folders with  similar content were present  in users  mailboxes  hence this impacted a lot on the growth of  edb[database]

Problem

  I have delegated  access- full  logged  into user mailbox  deleted  the folders  and the  content . infact  on mailbox usage on the  mailbox properties  I see markable reduction of the  size of the  mailbox   however all this does not replicate to  the database  size  the space it occupies on the  disk /drive.

  I have deleted   and emptied the  deleted folders  and set the  default retention to 0 days.  

But no change

[PS] C:\Windows\system32> Get-MailboxDatabase -Status | select ServerName,Name,DatabaseSize

ServerName                              Name                                    DatabaseSize
