Using New Outlook on Windows for professional communication and productivity
Hi, Akis. I am an independent advisor, trying to help other users in the Community with my experience in Microsoft products. Please note that I am a user like you and don't work directly for Microsoft.
I am sorry you are experiencing this on your Outlook. I apologize for the inconvenience. I will try to help.
Before we proceed, please confirm the device and OS you are working with.
If you are working with the Outlook app, I suggest looking for available updates. Sometimes, software updates can resolve unexpected behavior.
To isolate the issue, I suggest logging into your account via Outlook on the web.... to check if the issue persists there.
Try to start Outlook in safe mode and check if the issue persists, disable any third-party add-ins and see if it improves search performance.
Please let me know if it works for you otherwise, we can look into other possible solutions.
Regards
Femi
