Today i exported 10 users mailboxes from a exchange 2003 server to a 2007 server. Some via exmerge some via outlook as they were over 2gb. I then used outlook to import all the mailboxes one by one. Everything came in fine but when you reply to a mail from an internal user for old emails only, it is disaplying the x500 address and causes a bounce back IMCEAEX-_O=FIRST+20ORGANIZATION_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=TFREEMAN@al.local
Anything new is fine
I have been though a number of items and people are saying its due to the import/export but then they say to manually add the x500 address to exchange. Therefore i added:-
/FIRST ORGANIZATION/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=TFREEMAN@al.local
It still bounes. Ive looked at the "legacydn" in adsi and that is set as above, although it did orginally have a (xxxxxxxxx) at the first admin group section that i removed and then readded following a NDR.
Any ideas welcome!
