OFFICE 365: Cannot create folder in mailbox under NON_IPM_SUBTREE RRS feed

  • Question

  • I'm not sure when this occurred, but it seems that developers cannot create subfolders as children of the root mailbox folder (NON_IPM_SUBTREE).

    When i now open a mailbox, even my own, in O365 with MFCMAPI, the PR_RIGHTS on the root folder shows 'frightsReadAny' as the only right.

    Is there way to open an O365 mailbox with full access to the root folder, or at least enough to create a folder there?

    This is where a application developer would want to store configuration, cached info, or other app specific data without allowing a user to interfere.

    This used to work as recent a year ago.  Sometime in the past few months a change has been made that is really unacceptable.

    Can someone from MS confirm or explain this change to the root folder?

  • Hi,

    I would advise logging a ticket through the Office 365 portal and explain the issue to Microsoft. 

    If this is possible to unlock - they will tell you how it can be done.

  • I recently did that for a different issue (MAPI_E_STORE_FULL) and was redirect to this forum.

    I think Microsoft needs separate dev forumns for O365 and on-premises versions.

    Hopefully someone from MS will respond.
