Managing personal Outlook.com account settings, security, and privacy
Browser: Chrome (kept up to date)
Since Hotmail was "upgraded" to "Outlook" the reliability of connection to the servers has simply COLLAPSED. To the extent that, after using Hotmail as a primary email account for at least 15 years, I intend to bail out and transfer to Gmail. The occasional problem (infrequent in the past) might be acceptable. The current ABOMINABLE and continual unreliability makes Outlook simply useless.
I find it hard to believe that this problem continues to persist so long after it first appeared. As a retired IT professional I would have been fired if an application under my management manifested gross unreliability for such a protracted time.
Ironically in the past I have frequently recommended Hotmail/Outlook to my contacts on the basis of the clean interface and long term stability of the service. Egg on face. Currently I would suggest using even Yahoo (Yahoo!) in preference.
