Title: Users experience general latency when using Outlook on the web ID: EX384924
User Impact: Users are experiencing general latency when using Outlook on the web.
More info: Impact is specific to users with multiple instances of Outlook on the web open on the same device.
Current status: Our review of browser captures indicates that there's a code error causing requests to be sent via Hypertext Transfer Protocol (HTTP) 1.1 rather than HTTP 2.0, resulting in impact. As HTTP 1.1 doesn't have the flexibility and efficiency of 2.0, it's causing requests to queue before being sent to the server for processing. The service provider has developed and validated a fix which is currently being deployed, and they expect to have a remediation timeline soon.
Scope of impact: Any user with multiple instances of Outlook on the web on the same device may be impacted.
Root cause: A code error is causing requests to be sent via an older version of HTTP, resulting in inefficient processing and subsequently queued requests.

Title: Teams Android certified devices are logging out of AAD apps
User Impact: Users are seeing Teams Android certified devices logging out of AAD apps.
More info: The majority of the impact for Azure Active Directory (AAD) apps is specific to Microsoft Teams. Other Microsoft 365 services could also be impacted.
Impacted Android IP-based Teams devices include, but are not limited to:
- Poly, Yealink, Audiocodes Team Phones
- Poly, Yealink and Logitech Microsoft Teams Rooms on Android (MTRA)
- Teams Panels
- Teams Displays
While the fix will prevent any additional devices from being affected, users will still need to follow the mitigation steps outlined below to resolve the issue. For more detailed instructions, please see the following link:
https://docs.microsoft.com/en-us/microsoftteams/troubleshoot/teams-rooms-and-devices/signed-out-of-teams-android-devices
- Manually sign-in to the affected device.
- If a manual sign-in is not an option, perform a remote sign-out and sign-in operation using the Teams Admin Center (TAC).
- If this does not work, perform a remote device reboot through the TAC using the 'Restart' option on the device page within the TAC. Once completed, perform a remote sign-in operation.
- If this does not work, perform a manual restart of the device and then a manual log-in or remote TAC log-in.
- If this does not work, perform a factory reset of the device, then a manual log-in or remote TAC log-in.
Guides to use the TAC method to remotely log-in to the devices can be found at:
https://docs.microsoft.com/en-us/microsoftteams/devices/remote-provision-remote-login
https://docs.microsoft.com/en-us/microsoftteams/devices/remote-sign-in-and-sign-out
The required mitigation is a one-time action on a per-device basis; once an affected device has been signed back in, no further action is required to prevent a reoccurrence of this problem.
Current status: The fix has completed its extensive validation and we've initiated deployment of the fix, which has reached approximately 10 percent of the affected environments. We'll provide additional timeline information as soon as it becomes available.
Scope of impact: Your organization is affected by this event, which could potentially impact any of your Teams Android certified devices.
Root cause: A code defect was found in a segment of a recent code change that was intended to optimize service functionality, leading to an incompatibility with some form factor devices.
