Question

hi,

 I subscript messages and contact change notifications for the same user, the 2 subscriptions were created succeed, but I can only get message change notification. If I create a contact or update a contact on exchange, I can't get the change notification, but soon I will get a lifecycle notification, before a month,  use the same code , the contact notification works well.

Thank you for the help

Answer 1

Hi @Leila Lei ,

As per this Documentation, Missing of change notification could be because of removal of subscription. Certain events can cause a subscription to be removed:

• User's password has been reset
• User's device is out of compliance
• User's account has been revoked

Depending upon lifecycle notification value you are getting, you can try following suggestions given in the documentation:

• Upon receiving a subscriptionRemoved lifecycle notification, the app should recreate the subscription in order to maintain a continuous flow.
• On receiving a missed lifecycle notification, the app should resynchronize resource data using Microsoft Graph.

Also you can check this document on maximum expiration time of all the resources.

Hope this helps.
