Does it make you look unprofessional if you don't use Microsoft Outlook for professional/office related emails. At my workplace almost everyone uses Outlook. It is not mandatory but it is considered to be professional by many of them to use it. However, I simply use a browser for accessing my office emails. My reason for using browser and not Outlook is first of all it is pain in itself to successfully configure Outlook, at least I have never seen anyone configuring it in one attempt. Secondly every week someone's Outlook goes bad and they have to repair it and it wastes lots of time. Third you have to open a separate window on your taskbar for doing something which can also be done otherwise and probably better.
Personally I haven't have faced any issue using browser. So I don't think its unprofessional to not use Outlook for official emails. Should I stick with using browser or switch to Outlook.
