Can't enable a mailbox for archiving Event ID-3138

Hello,

Am trying to move an archive but when i try to enable the mailbox for archiving on the the server it's being moved to it fails and i'm getting a 3138 Event ID -  -Agent Client Broker Task.

An error occurred whilst enabling archiving for the mailbox /global mail / first admingroup......CN=Recipients/cn=userx

Error 0x80040115

I followed the link in the error log above and these settings are ok.

The user in question has had a name change and the path in the error points to her old username..could this affect it?

I am able to create an Outlook profile for her using her current name and server details.

Can anyone advise?
