View in File Explorer - Cookies are only Persistent for a week
TonyWilson Hi, according to the docs that UsePersistentCookiesForExplorerView the special cookie expires after 30 minutes when the KMSI isn't selected Set-SPOTenant (SharePointOnlinePowerShell) | Microsoft Docs
If selecting the KMSI it seems to be the default value in line with your experience? Session timeouts for Microsoft 365 - Microsoft 365 Enterprise | Microsoft Docs
Thanks ChristianJBergstrom
We have SSO so the KMSI won't come up. The persistent cookie won't expire at windows or user forced signout.
From your link "Session timeouts for Microsoft 365" it feel like the persistent cookie for View In FIle Explorer will expire after "SharePoint Online 5 days of inactivity".
That could be irrelevant of the KMSI, any SSO or other settings. That could be an independant token between SO and Edge. I will record the last time I accessed SO from File Explorer and see if that lasts 5 days.
Maybe that is the design: Access the SO files from File explorer when you click the view in SO, while the connection will remain live depending on your settings, for up to 5 days.
TonyWilson No worries, it's an interesting question so had to jump on it. Out of curiosity, have your org. configured persistent browser session and/or sign-in frequency using CA? Let me know the outcome of your testing if you have the time for it, thanks.
- ChristianJBergstrom It requested to sign-in again after 8-9 days.
I used the file explorer daily for SharePoint and left OneDrive untouched.
On the 8th (or 9th) day, the file explorer connection to SharePoint was not happening (same with OneDrive)
So using it daily is not renewing the connection. I am just doing the same test again to verify if it is 8 or 9 full days (will try to access it an hour before and an hour after the 8th day anniversary.
