Hi @BR, Rajesh ,
Appending a static ID to all incoming emails or removing the subject using a rule is not a standard feature in Outlook. However, there are some workarounds:
Appending a Static ID: In Outlook, you can create a rule to assign a category to incoming emails. While this doesn’t append a static ID to the subject line, it can help you organize your emails. Unfortunately, Outlook rules do not support modifying the subject line of incoming emails.
Removing the Subject: As for removing the subject line, it’s not typically possible with standard email client rules. The subject line is a fundamental part of an email and removing it could cause the email to be marked as spam.
