Somehow I manage to fix this issue as I faced same pattern of yours.
My life is becoming miserable due to Onedrive Shared Folder File as they are not fixing the explorer issue. I also added the Customise Network Location 5 days ago as just mentioned in the thread and after 2 days the map drive was not accessing despite entering proper details "MicrosoftAccount/(MYEMAILADDRESS)"
Firstly I deleted all the previous Customise Network Location that I added.
Then i opened the Office Uploader Center and searched for any "Pending upload" and "All cached file" that linked to the d.docs.live.net/(mynetworkadress). I cleared the cached files and make sure that there is no pending upload and paused the Upload (I resumed it later after fixing the issue)
Then I went to Credential Manager. Under the tab "Generic Credentials", I removed the Credential related to OneDrive that were created or modified in past 5 days (as I added Network Location 5 days ago for the first time) till today.
NOTE: (I could also see the credentials of "MicrosoftAccount/(MYEMAILADDRESS)" also modified today which I was attempting previously in "MicrosoftAccount/(MYEMAILADDRESS)". So I removed that too.)
Then I again reattempted to Add Network Location and this time the login details popped up without showing "MicrosoftAccount/(MYEMAILADDRESS)" in the User Name. There was only User Name and Password blank in a dialog.
Then I entered my Email Address and Password just like we login our normal mail from browser.
And it was a sigh of relief to see the folders in Explorer just OneDrive used to be in the past.
I think I should not tick the "Remember Credential" while entering Username and Password & should go through Office Uploader for any pending upload and Cached files to avoid again such issue.
I am not a Geek but if any one wants to ask related to above matter, I will try my best to explain.
If this helps anyone in the forum, then do reply.
