Missing contacts in migrated mails from Gmail RRS feed

  • Question

  • Hello technet folks!

    I migrated some accounts from Gmail Entreprise to Exchange 2013 on premise.

    Migration went pretty well .. I migrated 10 boxes by dumping PST with Outlook 2013 and google apps sync and reinjected the PST in Exchange account.

    Everybody got his old emails from Gmail in Exchange ... MX zone is migrated, they can received and send email correctly.

    However, they have a weird issue when answering to a mail they received BEFORE the migration from Gmail to Exchange. The mail is here, and when they click on "answering", the destination email does not exist anymore. Actually, the name of destination is here but not his email address. The vcard of the destination got the name, but all other information are empty (phone, company, email address). So if they send the mail, it will be bounced back ... with error '550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found'. If they replace the name with the real email address, then it works.

    Any idea why, during the migration the email address of each mail is not kept in its body ?

    Any help appreciated !

  • Hi Grey,

    The recipient in the old message which is received in old mail server may be resolved as a contact in old mailbox. But now, the mailbox is imported from PST file to the new Exchange mailbox. The old recipient can't be resolved if it only shows a name instead of email address.

    If you still want to just use display name to send message, please create a local contact in Outlook for external users. For internal recipients, please select them from GAL in Address Book.
