You are sure to do with the sorting of Outlook contact list, deleting old addresses that do not exist anymore, adding new ones. Usually we do not have any problems with new addresses adding but it is not so easy when it comes to the revision of the old addresses. Is it possible to check email addresses quickly for their validity? Is it possible to check all email addresses in Outlook mailboxes at once? Yes, now it is possible with Outlook Email Verifier plug-in. It is very easy to use: you simply select one or more messages in mailbox folders and launch the plug-in from Tools menu. Then the plug-in works and provides a report of dead and existing email addresses. The program has several exclusive features such as: a) Flexible SMTP-connection parameters setting. b) The possibility of different address types checking (From, TO, CC, BCC). c) The possibility of error log viewing (for the troubleshooting). d) The possibility of the work result exporting (plug-in allows the saving of the addresses with different status, e.g., existing addresses, or all addresses with validating errors, or dead addresses only).
