This article describes a 3-step process of moving mailbox data:
within one organization. The steps are:
- Export an existing mailbox data
- Change mailbox type in CONTROL PANEL
- Import the data to a new mailbox
Important: by design, both Exchange and POP/IMAP users are assigned an x500 Exchange address which is used for internal delivery by Exchange servers and is associated with an Active Directory object (not an email address). When you delete a user, their x500 address is deleted with the AD object, but it can remain associated with email addresses in Outlook and Webmail cache. If you receive the #550 5.1.1 RESOLVER.ADR.ExRecipNotFound non-delivery report after the conversion, try the following solutions:
- Remove the email address from the To field and type it manually when replying to an email.
- Delete the cached entry in your Outlook and re-create it for a new user. Read the Knowledge Base article on How To Reset The Outlook Nickname Autocompletion Cache for more information.
- Contact Support and provide them with the full text of the bounce back message to add an old x500 address to a new user AD object.
Note: if no bounce back is available, Support can obtain the x500 address from the Event Log. However, full bounce back message is needed to compare the addresses.
