The outlook 365 in windows 10 behaving strangely. one day suddenly it stopped working and I no longer could synchronize my emails. (Probably due to an update).
When windows is connected to my mobile hotspot the outlook works fine but as soon as I connect back to a home wifi network it stops synchronizing emails. I suspect that it is problem with the wifi router but all other devices such as phones and tablets are connected to wifi and emails and other functions work fine. I tried with another email client (Thunderbird) but the problem persists. Last night I had a three hours session with Microsoft support but all we could conclude was above.
OK, Finally, I found a solution. I did everything except uninstalling and reinstall office 365. I reinstall Office 365 and outlook works fine now.
