I have been using zoho mail within outlook on my android phone for many years however this past 6 months my zoho mail account keeps getting deleted from outlook.

Each week I have to re add the zoho account. This has been a real pain. 

Now however also I am unable to even add it. 

I see on the internet many others are having this same issue. 

What is the problem please? This is a huge inconvenience if I can not access my zoho mail through outlook.

Thanks
