You can fix this by doing the following steps.

1. Start active directory users and computers.

2. Enable the AD account .

3. Goto the properties of the account, under Exchange Advanced -> Mailbox Rights -> Add in the SELF object and grant it full rights, including the ‘Associated External Account’ permission. 

4. Wait for the changes to replicate.  This could take awhile be patient.
