Using classic Outlook for Windows in business environments

Please rest assured we are aware of large number of SPAM emails landing in the Inbox issue and have engaged the appropriate teams for further investigation and it will be fixed in a future update of the product. As an email service provider, we use several techniques to block junk or spam emails, including content filters, blacklists, and reputation scoring. However, spammers are always adapting and finding new ways to bypass these filters. Sometimes, spammers use advanced techniques such as spoofing the sender's email address or using compromised accounts to send spam emails, making it even more difficult for email service providers to identify and block these messages. Therefore, even with the best filters and spam detection algorithms, it's almost impossible to block 100% of junk emails. Email service providers constantly update their filters and rely on users to report spam, which helps to improve the accuracy of their filters over time. The SPAM emails issue is being worked upon at the back end for many customers facing this issue and there is no more technical troubleshooting regarding this concern to be done at our end.
