Possible limit to Presence subscription via Graph API

Hi,
I am trying to create an application that will subscribe to Teams Presence events using Graph API. I have seen that in general there are some limitations for the subscription for all the various resources as described in the following page: https://docs.microsoft.com/en-us/graph/webhooks

However it is not clear what happens with Teams Presence subscription. In the "Teams resource limitations" chapter only callRecords and chatMessages are mentioned. Is there any limitation on the number of Teams Presence subscription per application/ tenant etc? It would be really helpful to know these limitations.

Hi @CostasSome-1307,

Currently a single Graph change subscription to Teams presence can be created. When we try to add more subscriptions then we get the conflict error "A subscription already exists. It must be deleted before another can be made".
You can raise a UserVoice for your specific scenario so that it could be considered for future implementation.

Hi @Sheena-MSFT ,

Thanks a lot for the prompt response. The reference link that you posted was also really helpful.

So to sum up it seems that the limit is one subscription per user, and each user can subscribe for up to 650 separate user presence entitites.

But what happens with the total number of presence subscriptions per tenant/application etc? Is the total amount of presence subscriptions of all users that belong to a specific tenant limited any further? So in theory could every user that belongs to a specific tenant subscribe for up to 650 separate presence entities (so in the extreme scenario the total number of subscriptions could reach :
number_of_users * 650 )?

We meet this same problem. Is there any way to make more subscriptions per tenant?
