When do I have to log in to the MS Teams Bot again?

April 28, 2025 10:36 Updated

The following values are stored for the bot client:

AccessTokenLifetime = 3600, // 1 hour
RefreshTokenExpiration = TokenExpiration.Sliding,
SlidingRefreshTokenLifetime = 1296000, // 15 days
AbsoluteRefreshTokenLifetime = 15552000, // 6 months

This means that as long as the user communicates with the bot within 15 days, the login is extended by a further 15 days. After 6 months at the latest, however, the user is logged out and must log in again.

This applies to users who communicate with S4 via the bot. In other words, they can trigger acks and closes or alarms.

If a channel has been registered, S4 broadcasts to this channel indefinitely and every user who has subscribed to this channel sees these Signls.
