I’m using Studio 2021.4.4 and unable to access Shared Mailbox using Outlook or O365.
2021.4 release notes show this is a new feature.
MS Office syntax indicates \sharedMailbox\Folder is proper syntax.
Get Mail transaction list: Value cannot be null.
Parameter name: folderPath
Access no problem using Outlook client and same credential that developer/robot uses. Powershell commands also successful accessing shared mailbox.
Robot Outlook mailbox has owner permissions on Shared Mailbox and Registered application has Mail.Readwrite.Shared permissions.
I’d love to hear from anyone who has made this work!
