DescriptionLogon attempt by USERNAME from IP ADDRESS to EXCHANGE SERVER has failed: EcGetMailboxDN call failed with error. There is no such mailbox on this server.
Event InformationAccording to Microsoft:
CAUSE :

The credentials being passed from the client to the Exchange Server computer do not match the users Windows NT account and/or mailbox.
RESOLUTION :
1. Check the client configuration; please note that the steps for checking the configuration will vary depending on the type of client being used.
2. Change the account name to the format of NT_domain\NT_account\Exchange_alias.
3. Set the password to match the Windows NT password.
4. Save the changes, exit the client, and restart the client.
5. Connect to the Exchange Server POP3 service.
For an alternate resolution to this issue:
Change the alias name of the mailbox to the same as the NT account name. This will enable you to use one account name (instead of typing in the full path as described above).
