Hi, In Edge I'm not able to open a shared mailbox all of a sudden. Had no issues before. When I try opening a shared mailbox it opens my personal work mailbox instead. Definitely have read and access permissions to the shared mailbox. Have cleared browsing data for all time, tried repairing Edge and have no issues using Chrome. An ideas what the issue might be?
