Outlook 365 all accounts logged out after running CCleaner

[Suncoast_Bulldog]

Every time I run CCleaner Custom Clean I am logged out of all my gmail accounts that are linked to MS Outlook. There have to be some switches or exceptions to set to stop this happening. Thanks.

I don't have Outlook, is there a section for it on the Applications tab under Applications (along with the entries for Office, etc.).

If so then try unticking that.

If not then try unticking 'Session' for your browser(s).
Session is the information for that browser about what websites you are logged into, what browser tabs you have open, etc. when you exit the browser.
The browser uses that information to open the tabs and log you in again next time you open the browser, so if you clear the information then it can't do that.

Apparently I cannot edit my starting comment -- running CCleaner Custom Clean actually logs me out of all Microsoft accounts, Outlook, OneDrive, and Skype in my case -- all I need to understand is where is the setting or exception to prevent this happening.  I like to use CCleaner weekly but this is annoying to reset all the accounts every time.

I think it's network passwords under window explorer on the windows tab

Sorry. From your first post I thought it was just gmail that was being logged out, not Outlook itself.
I'd still uncheck 'Session' in the browsers that you use if you want to remain logged into webistes you access through the browser.

'Network Passwords' under 'Windows Explorer' are your Wifi connection logins rather than application logins.

Network Passwords - When you connect to a wireless network using Windows Explorer, you can choose to save the network password. Selecting this option will erase these saved passwords, which will leave you unable to connect to these wireless networks again until the password has been entered again.

OneDrive and Skype cleaning can be found under 'Applications' on the Applications tab along with Office versions (Outlook is part of Office), so you may want to take a look at those.

This documentation is completely wrong in my opinion. "Network Passwords" has always cleared the Windows password vault, i.e. everything that can be managed via the "Credential Manager". This includes e.g. passwords for file shares, but also the passwords of Outlook or other online services.

TBH I've never selected it, I'll pass your comment about the documentation upwards.
