Moving Mail in Verse using more filters

If a user moves an e-mail from Inbox to Meetings folder, it is displayed only in the Meeting folder.

But if the user searches for the e-mail by sender and folder (test N and Inbox). Then he moves the found e-mail to another folder (Meeting).

As a result, the e-mail is displayed/stored in two folders during a new search.

This is the normal behavior

If the user has just the folder chiclet in the search bar, then the action will be 'Move to Folder'.

If the user is performing a search using more filters (text search, from person search, etc.), the action will be 'Add to Folder'. In this instance, if the user opens the message, the user can see which folders the message is in. The user can manage those folders while the message is open. The user can add the message to another folder and remove it from a folder by using the "-" action next to the folder name.

Customer wants to improve this function

because It is hard for users to understand this difference when working with mail. During the day the user receives tens of mails per hour. And user does moving emails between folders using search bar and few parameters

Can this be fixed/improved?
