You receive a "Microsoft Outlook could not sign or encrypt this message" error message when you send or read a signed e-mail message in Outlook 2003 (826730)
The information in this article applies to:
- Microsoft Office Outlook 2003
- Microsoft Office Outlook 2003 with Business Contact Manager
SYMPTOMSWhen you try to send a new signed e-mail message or to
encrypt a new e-mail message or to decrypt a received e-mail message in
Microsoft Office Outlook 2003, you may receive the following error message:
Microsoft Outlook could not sign or encrypt this message
because your certificate is not valid. CAUSEThis problem occurs when your e-mail account has been
migrated to a new Microsoft Exchange server. The Key Management Services (KMS)
certificates that are issued to your e-mail account will not be migrated to the
new e-mail account unless they are correctly prepared for
migration.WORKAROUNDTo work around this problem, your system administrator must
reissue certificates for each user who was migrated to the new Exchange
server.STATUS Microsoft
has confirmed that this is a problem in the Microsoft products that are listed
at the beginning of this article.
MORE INFORMATIONAfter your system administrator issues new KMS certificates
to the user accounts on the original Exchange server, the administrator must
run the GalSynchronization Management Agent (GalSync) before using the
Migration Wizard to migrate the accounts from the original Exchange server to
the new Exchange server. This will let the certificates that are assigned to
each user account migrate correctly to the new Exchange server.
