Hi Harish,
By "Microsoft entourage mail app", do you mean Microsoft Entourage for Mac?
If this is your case, since
Microsoft Entourage is not supported by Microsoft now, I'd recommend you migrate to Outlook to get better support and user experience.
Then here we mainly focus on issues about Outlook, if your query is related to Outlook client, could you please provide the detailed version information and share the screenshot via
OneDrive then we can help you better?
Best regards,
Yuki Sun
