Restart recommended We detected that your session has unusually high memory - New Outlook

Anonymous

New outlook feels sluggish, after a few minutes and then after a minute or two a message popup "Restart recommended We detected that your session has unusually high memory". Restart and it works again for a few minutes. feels like a bug or memoryleak. After updates applied today. (Fully updates system)

Running classic outlook solves the problem, but just a heads up. If no one has a fix :)

Hello Martin,

Good day! Thank you for reaching out to the community.

It seems you're experiencing performance issues in New Outlook, with high memory usage leading to sluggishness and a restart prompt. I want to let you know that Microsoft is aware of a known issue affecting some users in Europe.

Known Issue Details
- Title: Some users in Europe may encounter performance issues with their Outlook client.
- User Impact: Users may notice Outlook using an increased amount of resources, causing the client to freeze or crash.
- Current Status: Microsoft is investigating telemetry logs and service diagnostics to identify the root cause and is developing a remediation plan. They have recycled components to reduce timeout errors, and further updates are expected soon.
If you believe your case may be related to this, feel free to update your issue accordingly.

Workaround

While Microsoft works on resolving this, switching to Classic Outlook has proven to be a temporary fix for many users. You can continue using this as a reliable option in the meantime.

The next update on this issue is expected by Thursday, October 10, 2024, at 1:30 PM UTC.

If you have any further questions or need assistance, please don't hesitate to reach out. We appreciate your patience during this time!
