I had a nice one today. I saved an email for archiving for all to see ( you know, as a .msg) and tried to open it. Windows asked if I would like to open it with Outlook (new). Sure, I thought, only to be greeted by the message “sorry, this function is not supported”.
Why do you do this to me Microsoft?! Why?!
I use them as well. Cheap, reliable and easy to use. I only had trouble once, where I was caught in some sort of anti-spam measure and they blocked my account. An email to their support fixed the problem pretty quickly though.
One thing to look out for is to determine where you want your backups. You can’t change your account’s server location after you create your account afaik.
