the smtp address already in use - Public Folder

allylaurente

Hi Guys,

I have this problem when someone requested to create a distribution list with preferred email address. When i add the email address manually i received an error that "the smtp address already in use". I can't resolved the address in outlook and i received NDR when sending to the smtp address. I suspect that the address is attached to a mail enabled public folder that is hidden in GAL.

Question is how to know the path of the public folder that has the smtp address.

Thanks in advance.

I doubt it's a public folder. Rather, it's probably a contact that had a secondary address applied to it by an address policy. Do a search in the All Contacts section of your address book (which will search the online GAL rather than the offline address list) for a contact with the same name as the distribution list email address you are trying to create.
