Unable to access Shared Mailbox through Outlook or O365

This is resolved. Correction and Resolution below.

Correction: Problem was accessing Group Mailbox (not Shared Mailbox) using O365 Activity.

Resolution: I needed to use the Group Mailbox account in the Get Mail Activity (including domain: GroupMailbox@mymail.com).

While Outlook has the Group Mailbox visible, in O365 that really isn’t what it is doing. It needs the Group Mailbox in the Account parameter.

Syntax for folder path within the mailbox is folder\subfolder
