Hi All,

A user has delegated access to a shared mailbox.

Recently some messages were sent to that shared mailbox but not showing up in the user's Outlook.

Those message are searchable but not opening.

I tried to convert the shared mailbox to a regular and delegate access from the mailbox itself but getting this error.

How to let the user to open those private messages in the shared mailbox?

Thanks.
