Pull Subscription is lost if I reconnect to the server RRS feed

  • Question

  • Hi,

    I have the following scenario:

    - Connect to a mailbox on Exchange Online using EWS Managed API 

    - Subscribe to a PullSubscription, and saves the watermark (subscribe using SubscribeToPullNotificationsOnAllFolders)

    - Disconnect from Exchange Online

    - Reconnect later to Exchange Online, and send in my watermark

    - Call GetEvents

    This results in no events, even though I know there are new emails and calendar entries in the mailbox.

    I see that if I do not disconnect/reconnect my ExchangeService instance, then I get events as I should.

    Are Pull Subscriptions tied to a specific instance of ExchangeService?

    Best,

    Stein J. Gran
