Hello
First, when you create a massege and start entering a name, it displays a mailbox that no longer exists (the icon displays the words "organization"). Moreover, I checked, it is not in the address book (including by organization).
Second, there's the problem with aliases.
User Mike (for example) has several aliases. I transferred one of the alias to another user, but when you write a new massege, the old user appears next to the nickname!
Also, when you copy an alias, the username is displayed next to the mailbox, not the alias
And in general, when there is a correspondence, a lot of quotes appear next to the username (looks like ''''''Mike'''''')
Any idea?
