Problem solved I am not sure what "rebuilt" meant but I thought it meant creating another profile. Creating a new profile did indeed get rid of the additional mailbox. I was looking for a means to fix the original profile as it would necessitate uninstalling then reinstalling a piece of software that is tied to the user profiles.
I finally uncovered the problem to be a registry Key that for whatever reason did not get removed when I removed the additional mailbox in the advanced tab. Deleting this Key resolved my problem I have included the key and some of the values that I exported from the Registry for future reference for anyone that is interested Key - [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Vantine\2b1df5b7b333f6439b0c2048bcf83275] Values - "001e3001"="Mailbox - training" "001e3006"="Microsoft Exchange Server" "00033e03"=hex:21,00,00,00 "001e300a"="EMSMDB.DLL" "001e3d13"="{6485D26A-C2AC-11D1-AD3E-10A0C911C9C0}" "00033009"=hex:40,08,00,00 "0003660a"=hex:02,00,00,00 "01023414"=hex:9e,b4,77,00,74,e4,11,ce,8c,5e,00,aa,00,42,54,e2 "00036609"=hex:0c,00,00,00 "01023d0c"=hex:10,8a,02,32,83,b8,fa,40,ab,27,d5,3f,2e,5d,4e,00 "001e3d09"="MSEMS" "001e660b"="/o=Creative Computing, Inc./ou=CREATCOMP/cn=Recipients/cn=training" "001e660c"="ENTERPRISE" "001e6614"="/o=Creative Computing, Inc./ou=CREATCOMP/cn=Configuration/cn=Servers/cn=ENTERPRISE" ....
