    Hello Karen,

    Thanks for posting your question in the Microsoft Q&A forum.

    In the context of Microsoft Graph , the storeId mentioned in the error message refers to a unique identifier associated with an Outlook folder.

    Each folder in Outlook also has an ID field called Folder.StoreID. The value of StoreID remains the same for all the folders within a particular message store (such as your mailbox). It uniquely identifies the mailbox or data store where the folder resides.
