Using Outlook for Android in business environments for email and scheduling
I had this problem for the first time today when trying to log-in to my Hotmail account on my home computer. Logging-in requires me to log-in to my Microsoft account & that is 'protected' by a code being sent to me on my mobile phone.
All proceeded OK until I tried to enter the code supplied to me by Microsoft via my mobile phone. On entering the code on my computer I got the "Too Many Requests" message & could go no further.
Looking for help I went onto the "Contact - Microsoft Support" page & basically got nowhere because this paricular error wasn't recognised by the automated sysems used by Microsoft support.
To try & get further help I saw the "sign-in" icon on the top left of the page & decided to try that route.
No problem - I signed into my Microsoft Account as usual, including entering the code sent to me by Microsoft.
As I was then signed-in, I could access my Hotmail account with no further problems.
OK, so what happened? No idea - could just be the server was no longer so busy, but I just don't buy that. Could be that using a different system/software got round a basic "bug" in the current Outlook software - yep, that seems more likely to me.
