Hello,
When there is a network connection loss, or a connection change, em Client is no longer able to recover and share data with Exchange server.
It occurs, for example, if you change your wifi access from an access point to another.
The situation is that activity windows remains with actions in progress but nothing occurs on the main widows, no new messages, no messages sent, no update of calendar…
