Guest does not show which email addresses are blocked on multiple sharing

[GeraldLeikam]

If domains are blocked for sharing and you enter several addresses in a multiple share that are blocked, this will not be accepted as desired and no guest user will be created. Sometimes guest gives the email addresses in a message at the top, but not all of them. This usually occurs when more than one domain is on the blocklist.

Enhancement suggestion:

• The popup "Error while sharing" could list the failing email addresses
• The popup "Error while sharing" could list some details, error codes, messages.
