To use multiple backends, Customize `eudc-server-hotlist'.  The command
you tried above will give you results from the first entry in the
hotlist.

Additionally, this:

C-u M-x eudc-expand-try-all RET

will give you a list to choose from, of the completions from all servers
in the hotlist.

(There is also M-x eudc-set-server which sets the `eudc-server' and
`eudc-protocol' variables, but you should probably just ignore all them,
and focus on getting `eudc-server-hotlist' configured to your liking.

This is an area I want to reorganize.  Alexander has suggested having
the `eudc-server' and `eudc-protocol' variables "point" into
`eudc-server-hotlist'.  Basically, I'd like the hotlist to be the only
place the user needs to configure backends.  We'll have to be careful to
retain backward compatibility here though.)

Agreed, but also LDAP and macOS contacts, other sources of email
addresses.  And ideally without the user needing to configure
message-mode hooks to change keybindings, by default.  And ideally
introduce all this in a backward compatible way.

One approach I see working for what you want, would be to add new EUDC
backends for each of mail abbrevs and ecomplete, then in message-mode,
make `eudc-expand-try-all' the default owner of the TAB keybinding when
point is in a To:, CC: or other field that wants an email address.
