Since a few days we have issues getting Outlook calendar data pulled. When verifying the Microsoft Exchange Account settings, we suddenly get following error upon save: "The request failed. The underlying connection was closed: An unexpected error occurred in a send."
The application is being hosted on a WS2016 1607 environment with .NET 4.5.
Should this have something to do with TLS? Fast research pointed me to https://docs.microsoft.com/en-us/answers/questions/362284/error-the-underlying-connection-was-closed-an-unex.html and to https://stackoverflow.com/questions/28286086/default-securityprotocol-in-net-4-5 but not sure.
Please advise.
