EV can work with both of these.
For Bloomberg you will need a Bloomberg Importer utility, third party app.
For IM if you use IM Manager ( now owned by Symantec) it can import directly into an archive, other wise you set it up to be exported to a journal mailbox and it gets imported that way. You have some options so I would recommend approaching you sales person.
You may wish to search this forum for Bloomberg and read up on previous conversations, as it has been discussed a few times.
Here is one link for you to read up on:
