A device comprising: a processor, a memory, and a notification device, the processor adapted to: manage a first workspace and a second workspace distinguished from each other by accounts being associated with the one or the another of the first workspace and the second workspace; each of the first workspace and the second workspace being further distinguished from each other by respective partitions of the memory; and, when a current workspace comprises the first workspace, control the notification device to present first notifications associated only with the first workspace, while second notifications associated with the second workspace are not presented; and to store messages received at the device and associated with the second workspace while the current workspace comprises the first workspace, and when the current workspace changes to the second workspace, control the notification device to present one or more of: the second notifications of the messages that have been previously stored; a given number of the second notifications of the messages that have been previously stored within a given time period; and the second notifications of the messages that have been previously stored within a given time period, characterized in that the memory is adapted to store exception conditions and the processor is further adapted to control the notification device to present the first notifications and the second notifications associated with one or more of the exception conditions, regardless of whether the current workspace comprises the first workspace or the second workspace. a processor, a memory, and a notification device, the processor adapted to: manage a first workspace and a second workspace distinguished from each other by accounts being associated with the one or the another of the first workspace and the second workspace; each of the first workspace and the second workspace being further distinguished from each other by respective partitions of the memory; and, when a current workspace comprises the first workspace, control the notification device to present first notifications associated only with the first workspace, while second notifications associated with the second workspace are not presented; and to store messages received at the device and associated with the second workspace while the current workspace comprises the first workspace, and when the current workspace changes to the second workspace, control the notification device to present one or more of: the second notifications of the messages that have been previously stored; a given number of the second notifications of the messages that have been previously stored within a given time period; and the second notifications of the messages that have been previously stored within a given time period, manage a first workspace and a second workspace distinguished from each other by accounts being associated with the one or the another of the first workspace and the second workspace; each of the first workspace and the second workspace being further distinguished from each other by respective partitions of the memory; and, when a current workspace comprises the first workspace, control the notification device to present first notifications associated only with the first workspace, while second notifications associated with the second workspace are not presented; and to store messages received at the device and associated with the second workspace while the current workspace comprises the first workspace, and when the current workspace changes to the second workspace, control the notification device to present one or more of: the second notifications of the messages that have been previously stored; a given number of the second notifications of the messages that have been previously stored within a given time period; and the second notifications of the messages that have been previously stored within a given time period, characterized in that the memory is adapted to store exception conditions and the processor is further adapted to control the notification device to present the first notifications and the second notifications associated with one or more of the exception conditions, regardless of whether the current workspace comprises the first workspace or the second workspace.
