In Dynamics 365, we can now define Session timeout and Inactivity timeout.
We need to go Settings à Administration à System Settings à General Tab
By default, the session timeout is set to 24 hours along with 20 minutes for warning the user.
We can set our custom values there.
| Enter maximum session length | 60 – 1440 minutes. ( 1 to 24 hour) |
| How long before the session expires do you want to show a timeout warning? | 20 – 1440 minutes. Must be less than maximum session length. |
We can also set the timeout based on inactivity. By default, this setting is not enabled. Below are the values that we can set for inactivity timeout.
| Enable session timeout due to inactivity | 5 – 1440 minutes. (5 minutes to 24 hours) – Must be less than the maximum session length. |
| How long before the session expires do you want to show an inactivity warning? | Less than Session timeout due to inactivity |

I am using Dynamics 365 Online and configured custom Session timeout and inactivity timeout. But due to some reason , even if I disabled them, it is still popping up for inactivity timeout warnings. Is there any other way I need to configure other than Settings > Administration > System Settings?

Ideally if disabled it should not show the inactivity timeout warnings. For session timeout we have the default values even if we do not enable it unlike inactivity. Does it occur for all the users or some specific user ?

Is it possible to increase the Maximum Session Length (Session Timeout) to 1 week or ‘Never Timeout’ as it’s very annoying when every day I lose the connection for my CRM pages that I am monitoring and have to close down the pages. CRM should offer facility to keep session open, or to resume your previous open pages (like Chrome).
