I think the below might be the reason? It happens when I have below type of
user name entries. When I try to resolve "foo, user", it doesn't get resolved
but "foo, user(dept1)" gets resolved successfully.
Please note that both of above users are different. Do you think any
connection with these entries and naming resolution?
Moreover, I tried doing it from Outlook look up but I didn't see any
difference. For example, when I copy "foo user" in To list, and press Cntl+K,
it gives me pop-up for selecting between "foo user" and "foo user(dept1)".
The same pop up appears when I do look up for "foo user(dept1)". Not sure
where is the issue. I might need to check how resolve query works.
