Mounting and Dismounting Mailbox Stores

There will be times that you need to dismount a mailbox store on the fly. This could be for integrity checking, mailbox restorations, or to make email unavailable to some users for some reason. When you dismount a mailbox store, users with mailboxes in that store will be unable to retrieve their mail; users with mailboxes in other mailbox stores will be unaffected.

Using a graphical user interface

  1. Open the Exchange System Manager (ESM) snap-in.
  2. In the left pane, browse to the server and storage group that contains the mailbox store you want to manipulate.
  3. Right-click on the mailbox store and select Dismount Store.
  4. Click Yes when prompted to continue.

Using VBScript

' This code mounts/dismounts a Mailbox Store.
strServer  = "<Exchange Server>"     ' e.g., ExchServer2

strSGName  = "<Storage Group Name>"  ' e.g., SG1

strMailStoreName = "<Database Name>" ' e.g., DB1

' ------ END CONFIGURATION ---------' Find Storage Group URL

strSearch = "CN=" & strSGName  & ","

set objSrv = CreateObject("CDOEXM.ExchangeServer")

objSrv.DataSource.Open strServer

for each sg in oSrv.StorageGroups

if (instr(1,sg,strSearch,1)>0) then strSGUrl = sg


' Generate Mailbox Store URL

strMBUrl = "LDAP://CN=" & strMailStoreName & "," & strSGUrl

' Open Mailbox Store

set objMb = CreateObject("CDOEXM.MailBoxStoreDB")

objMb.DataSource.Open strMBUrl

if (objMb.Status = 0) then

Wscript.Echo "Mailbox store is mounted, dismounting..."



Wscript.Echo "Mailbox store is dismounted, mounting..."


end if

Wscript.Echo "Script completed successfully."
