When I type an email address it looks in our Exchange address list- this is ok.
But...
It offers all the possible email addresses assigned to that mailbox. We have to have these, its just how its setup but for each person it offers as much as 4:
e.g,
joe.bloggs@acme.com
joe.bloggs@acme-uk.com
joe.bloggs@acme-ltd.com
and so on.
Send to any of these addresses will receive in Joe's mailbox.
Can you set it to only see the default and primary (I believe it is bold in Exchange Server options under 'Email Addresses')
Not a problem for me, but want to avoid confusion for our users.
