i am having the same problems with the computer and also with my phone an Lumia 950 XL the email , calendar and everything related vanished suddenly, when try of watch the accounts on the hamburger menu just there is no accounts althought the system
on settings, your e mail and accounts are my accounts there but outlook do not watch them at all, i have done hard reset twice to my phone and do not occur nothing, looks like what can do while seek an solution to the fail of tuesday patch , the only
solution is that when do hard reset set the store to turn off update apps automatically when i´m on wi-fi and avoid update the outlook mail and calendar if appear on the update list stop the update or download , this sounds weird but also avoid update
to the release of windows mobile that was released on tuesday also and stay on the version 1511 compilation 10.0.10586.318 because looks that the last update is the buggest one , i am very dissapointed about this mobile operative system , since windows 7.8
that have not been that buggier, and looks like insiders do not really helps at all to the platform than just wait or by compulsion download an technical preview without any technical knowledge and have to say amen to any set back that the platform do
at this part of the development of the system do not see the point of have civilian people testing betas and only should test experts and not an person that just know how to turn on and off an computer and believes that the only solution to any problem
on windows is solved by c: format
Also the corrupted file is an very weird thing, in an mobile if were an corrupt file that would mean that the unit sold are defective in terms of hardware or two the file got corrupt while was downloaded but is odd since there is system to detect
such situations and show to user "update failed" to make start again the update.
also i am not insider anymore since have nothing to do with an beta operative system or have any thing to suggest to the development team.
best regards
