Using Classic Outlook on Windows for personal email, calendar, and contact management
As a product manager, I understand the strive to making the product simpler and remove unnecessary features. The old outlook admitably is cluttered with too many features. They have my full support there.
Yet, I believe it was a short sighted decision to remove the multi-language spell checking. It shows they don't have a good understanding of ways of working in our cultures. Unlike in US, in Europe, we live in a continent with many languages and people are often multi-lingual or have learned multiple languages.
When I compose emails in any language other than the default language, I end up having red line under most of the text of the email which is disturbing. Additionally, the spell check is almost mandatory when I write email in a language which is not my native language.
I strongly recommend outlook team to reconsider adding multi-language spelling check. Specially now a days using AI, it should be easy to detect the language and automatically spell check the correct language.
