Microsoft 365 Exchange Online: Synchronize subfolders or categories

In the "Advanced settings" of a® connection, if a subfolder is defined as the sync source or target,® will now automatically create this folder when needed. In newer versions of Outlook, contact folders are also referred to as "categories". This subfolder must be created either by®, Outlook for Windows, or Web in order to be synchronized. Folders created differently (e.g., via Outlook for Mac) unfortunately cannot be synchronized due to a Microsoft bug.
