Updated June 8, 2023: We have updated the timing outlined below. Thank you for your patience.
Debug log files are automatically produced by the Microsoft Teams client, which can aid in monitoring and troubleshooting Teams. Also known as “Web logs”, Debug logs have historically been constrained by a limited memory buffer. If not collected by the user immediately after an issue occurs, the “signature” of the issue may not be present in the Debug logs, making it more difficult to resolve recent and future issues.
This is being addressed with Continuous Web Logs (CWL). With CWL enabled, once the in-memory buffer reaches the limit, log lines will be saved to a file on user's machine extending the log capturing window up to one business day for an average user, providing a significantly larger window for troubleshooting.
CWL is available to all tenants, but currently disabled by default. Teams' admins are able to turn it on using either of these methods:
Assigning TeamsMediaLoggingPolicy via PowerShell cmdlets
Setting a Feature Flag enableContinuousWebClientLogging to True. This can be done with assistance from Microsoft. As a temp solution, {enableContinuousWebClientLogging: true} can be added to hooks.json locally for the user. This will override the ECS setting for the user and enable CWL.
Soon, Teams admins will have an additional option to enable CWL from the Teams admin center.
[When this will happen:]
During June, 2023, CWL will become the default for Teams users with the following desktop system specifications:
Intel Core i3 and Core i5 (generation 10 or higher), Core i7 and Core i9 (any generation) excluding the following series: U, Y, G1-G7, UE, UL, M, QM
Intel Xeon
AMD Ryzen 5, 7, 9 and TR models excluding U series
Apple Silicon (all series of M1 and M2 chips)
Admins may use the methods listed above to enable CWL for Teams users with lesser system specifications. CWL will not be enabled by default for all machines to avoid the potential for user impact on lower-end devices.
