I have same issue. Edge after each restart asks me to log in (top left corner). Same for Office 365 apps. Even sticky notes asks.
I do not need to enter password, just click ok on SSO, but this is so annoying and obviously sync is not working until I am logged in in each app.
This started to happens not that long time ago. Probably an update?
@ArnoudM I think you do not see that option, cause you do not use local account on your device, but Microsoft account - same as I do.
This device is also bound with MS account. So you cannot remove your main account, until you will turn off windows hello, switch to local account and then you'd be able to remove MS account. However, this is not a solution for your and mine problem, cause all is about using MS account without constantly being asked to log in.
I think that clearing Windows and websites credential storage (control panel) might be worth of try. After doing so, you will need to log in again, but hopefully one time. To do not click every single records, here is single liner powershell script to do it:
| cmdkey /list | ForEach-Object{if($_ -like "*Target:*" -and $_ -like "*microsoft*"){cmdkey /del:($_ -replace " ","" -replace "Target:","")}} |
|---|
Perhaps also removing device from Microsoft account and re-add it again would help?
I haven't tried none of above yet, cause I must prepare myself. Meanwhile I hope some solution or confirmation will be posted.
If not, I will try soon and let you know did it work.
