After switching a mailbox, a duplicate SMTP redirector address is added on the target user (4275752)

The target redirector address is placed on a target user once the user has been switched.   This allows mail forwarded from the source to arrive in the target.

However, if the address being applied (for example, jsmith@target.local) already exists in the Exchange organization, QMM will add the address regardless, resulting in a duplicate entry which may cause NDRs.

This had been identified as a product defect.

Changing the target SMTP address template will resolve this issue.

This issue will be fixed in QMM 8.4.
