Email address resolving to old user

Hi there,

We recently reassigned an old email address from an ex-employee to a new hire however Acrobat continues to resolve the address to the old user name so that signatures from the new user are labeled as coming from the old user. We've removed the old user from our account and Business ID and added the new user's details but it seems that somewhere the address is still assocaited with the old user.

Does anyone have any ideas for where else I need to purge the old user details to prevent this happening, or is it just not possible to reuse the same email address for a different user once it's already been used?

Many thanks
