Hi,I'm already able to create a user mailbox through FIM but I would like to create more than one SMTP for each user. For each user I would like to have, as an example, the smtps: user@fim.local and firstname.lastname@fim.pt. I know that this info is stored in the attribute "proxyAddresses" within the AD, and I tried to concatenate a string to it but it is a collection...As anybody done something like this? Can anybody help me?Thanks

You should create a new multivalue attribute in the FIM portal and link this to the user object. Remember to include this in your Sync Rules and in the flow rules for the FIM MA.

The Proxy Address can be stored in the preexisting attribute Proxy Addresss Collection on the user information in the FIM Portal. Just select the user, go to advance view and search for the attribute Proxy Address Collection.
