Change of users name causing Windows Azure Active Directory Connector Export error

We are encountering an issue with a user whose first name recently changed (shortend) in AD and is now causing a sync error in online Dymanics CRM.

The error we are seeing is as follows:

Unable to update this object because the following attributes associated with this object have values that may already be associated with another object in your local directory services: [ProxyAddresses SMTP:firstname.surname@domain.com,smtp:firstname.surname@domain.com;Mail firstname.surname@threalestate.com;]. Correct or remove the duplicate values in your local directory.

We can see in Dynamics that both the users username and email address have been updated to the new amended value (although the first name field has not)  but will still see this error being reported.

We have run 'IdFix DirSync' which did not flag any errors for the above account.

Has anyone else encountered this issue before when updating a users name in AD for online Dynamics CRM?

Many thanks

David

This happens when someone edits an object in an inappropriate way. Dirsync starts with a soft match, but once that is done, a GUID is written in AD and subsequent syncing is done as a hard match using that GUID. This usually means you can edit things safely, but there are instances where someone decides to get 'creative' and they break the object. You'll have to re-create the hard match now. Or delete the account in CRM/Azure AD and let dirsync create a new azure object, which has data-loss potential.

Simply do a Bing search for dirsync hard match and a TechNet blog should be one of the first results. I'd search and post it myself, but I am mobile at the moment so search and cut/paste isn't easy. Still, the process is relatively painless and finding the blog should be easy
