2010信箱搬移至2013/2016時，OUTLOOK無法連線

將從2010信箱搬移至2016時，有時用OUTLOOK 201X信箱會無法連線，autodiscvoer打完密碼後無法継續下個步驟就停住了，但OWA郤可以正常進入

在每一台2016上執行，Restart-WebAppPool MSExchangeAutodiscoverAppPool，重設過等個五分鐘就正常了

Solution 02:

As written in KB 3097392 the MSExchangeAutodiscoverAppPool needs to be restarted on the affected Exchange 2016 server (keep noted if you have a cluster you need to perform that on all of them)

Restart-WebAppPool MSExchangeAutodiscoverAppPool

You might wish to run that on a periodic state (e.g. every 30min). If you wish to do that check the follow URL.
