MC288052 Reminder: IE11 desktop application retires in 9 months on June 15, 2022 – Set up IE mode today (non-LTSC, non-Server) If your organization has legacy sites and apps with IE dependencies, you will need to set up IE mode so that users can access them through Microsoft Edge. Microsoft Edge, with Internet Explorer mode, is the only browser with built-in compatibility for legacy IE-based sites and apps. It also gives your organization world-class compatibility with a dual engine advantage:
Microsoft Edge renders IE-based sites and apps using IE mode.
Microsoft Edge renders modern sites and apps using Chromium.
IE mode support follows the lifecycle of Windows Client, Server, and IoT releases at least through 2029. Additionally, Microsoft will give one year notice to deprecate the IE mode experience in-market when the time comes.
Note: After June 15, 2022, the IE11 desktop application will be removed via Windows update. We do not recommend avoiding Windows updates to keep IE11 as Window updates contain critical operating system security patches.

MC275807 (Updated) Removing Message Trace in SCC. Move Custom Queries to Message Trace in the new Modern EAC. You will not be able to use Message Trace in the Security and Compliance Center after October 5th, 2021. Message Trace has the options to use default queries, custom queries, and autosaved queries.
Custom queries in Message Trace in the Security and Compliance Center portal will not be migrated to the new Modern EAC portal. Message Trace custom queries in the Security and Compliance Center are stored differently from custom queries on Message Trace in the new Modern EAC.
Another key difference in Message Trace in the new Modern EAC portal is that your custom queries are stored on a per user basis unlike Message Trace on SCC where custom queries were being stored on a per-tenant basis. Therefore, in the new Modern EAC a user will not be able to see a custom query created by another user. In the SCC, when a user created a custom query, other users were able to see the custom query created due to it being stored at the tenant-level. This is due to privacy and security reasons for EAC.

Additionally, they will no longer receive APP/MAM feature and security updates once the Company Portal is removed on September 23, 2021.

MC288052 Reminder: IE11 desktop application retires in 9 months on June 15, 2022 – Set up IE mode today (non-LTSC, non-Server) As announced in MC257152 (May 2021), the future of Internet Explorer on Windows 10 is in Microsoft Edge. Internet Explorer mode (IE mode) provides legacy browser support within Microsoft Edge. Because of this, the IE11 desktop application will be retired on June 15, 2022. This means that the IE11 desktop application will no longer be supported and afterwards will redirect to Microsoft Edge if a user tries to access it.
With 9 months left before retirement, we highly recommend you start preparing today. The essential first step—Site Discovery—typically takes 3-4 weeks.
Internet Explorer 11 desktop application
Timing: The IE11 desktop application will be retired on June 15, 2022
Windows 10 LTSC and Server not affected. For a full list of what is in scope for retirement, see the FAQ.
Action:
To continue using a supported browser, transition to the Microsoft Edge.
To continue using legacy IE-based sites and apps, you will need to configure those sites and apps to open in Microsoft Edge using Internet Explorer mode.
Start setting up IE mode by performing Site Discovery (3-4 week process depending on the size of your organization). This is also available as part of the Configure IE mode guided experience in the Microsoft 365 Admin Center.
