Asynchronous Remote Event Receivers does not fire sometimes on the Document Library in SharePoint Online


  • Hi,

    I am currently working on Remote Event Receivers which are attached to the SharePoint Online Document Library through a Provider Hosted App.

    ItemAdded and ItemUpdated (Asynchronous Events) are attached to the Document Library

    I am facing an issue, where the ItemUpdated Event does not fire sometimes. For example: The event fails to fire once out of 10 times. This is not consistent. Sometimes it fails once in 26 times. 

    The exact cause of the event not firing is not known. Have looked through the IIS Logs and whenever the event does not fire, a POST Request log entry to the Event Receiver Service is not present in the Logs.

    Has anyone faced this issue before ?

    Any help would be appreciated. Thanks in advance.

    Regards, Arcee Gomes
