Is there a speed limit for MSFT (Outlook Mail) graph?
I am currently building a small application that will provide users with the ability to mark multiple email messages as "read" with one click.
Unfortunately the MSFT API does not support multiple update calls as stated here
So now I am using the asynchronous part of the IO server to send multiple REST API requests at the same time.
I know there is a limit of 60 requests / min. But is there a limitation on simultaneous communication?

There is a simulated connection limit as storage access is serialized. I would recommend going with 4 concurrent requests in max (maybe even lower). From an Exchange store perspective, all store access is serialized regardless of the application.
Microsoft Graph also plans to support batching soon, so by enabling it you can make one call and update the read flag for multiple messages.
