I got this warning when I moved an Exchange 2003 mailbox to the cloud.
In the last step of the move, the Onpremise mailbox should be converted into a mail user.
Attributes and target address should be pointing to the cloud.
In this case, it seems like, the on-premise mailbox was not getting converted into a remote mailbox and the attributes need to change manually.
Before changing anything, check that you still see the old mailbox, if so backup all the x500 address.
From Adsiedit – properties on the AD User:
First clear the following attributes
1. homemdb
2. homemta
3. msExchHomeServerName
4. msExchPoliciesExcluded
Now add the following:
1. msExchRemoteRecipientType="4"
2. msExchRecipientDisplayType="-2147483642
3. msExchRecipientTypeDetails="2147483648"
4. targetaddress: SMTP:alias@tenant.mail.onmicrosoft.com
Add x500 address you backed up if they don’t exists
Now Sync AD using Dirsync
That’s worked for me.
Good luck J
