We’re sorry you’re having trouble with Sticky Notes sync errors in OneNote for iOS and Android phones. Please follow the steps in this article to resolve the issue.


In certain configurations, Sticky Notes may display an error message indicating a sync error with the following informational text: 

  • “Sticky Notes currently requires an Exchange Online mailbox for sync and storage to work. Please contact your IT administrator about enabling a mailbox or use the option below to learn more.”

After encountering this error, newly created or edited Sticky Notes will not be synced. The data is persisted only locally within the app and it is not backed up.


Sticky Notes functionality in OneNote currently requires an Exchange Online mailbox in order to store and sync your Sticky Notes. Since these are crucial functions of Sticky Notes, you won’t be able to sync your notes until you have an Exchange Online mailbox.  


We’re unable to support on-premises Microsoft Exchange mailboxes, but we are working to support more account types in the future. In the meantime, it’s best to contact your IT administrator about getting access.
