Outlook ost registry setting

[dl907687]

I need to delete a registry setting for outlook whenever a user logs on through a login script. Unfortunately one of the keys in the key name is unique to the user (see below, the key in this instance is "Exchange Profile dl907687", where dl907687 is unique to the user, i.e. another user could have Exchange Profile dl929687.)
Is there a wild card command I can use with regedit?

[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Exchange Profile dl907687\13dbb0c8aa05101a9bb000aa002fc45a]
