Autocomplete cache after IMAP migration RRS feed

  • Question

  • Dears,

    We are migrating from Rackspace to Office 365.

    After the migration completion i think we will face issues with Autocomplete cache for internal and external users that are sending to our environment they will receive DNS resolution error.

    is there any solution for the above especially for the external users?

    Best Regards,

  • Hi,

    The Autocomplete list contains SMTP addresses, LegacyExchangeDN entries, and display names for people to whom you have sent mail previously.

    In your case, we can clear the old autocomplete list and recreate new entries. To do this, please click the “X” in the list.

    We can also go to File > Options > Mail > Send Message section. Click Empty Autocomplete List. This will delete all entries.

    Hope this is helpful to you.

    Regards,

    Perry
