Issue: You get an error on SharePoint saying something like ‘The drive is already mapped blah blah blah.”

Solutions:

1. a) Net use – will list all the mapped drives on your system, even the ‘ghost’ ones (without letter assigned). Remove it with net use /delete followed by full address of drive destination;
2. b) If net use did not show anything – just assign a drive a different letter.

Tips

1. Add the following to Trusted sites in Internet Explorer 

https://Client’sSharepointAddress

2. Before you map a drive, login to Office 365 via Internet Explorer and tick ‘Remember my credentials’;

3. Open the full clients address in internet explorer and make sure it opens the files without any logon prompt so
   https://sharepointsite.sharepoint.com/personal/USERNAME/Documents/

3. Go to Services and make sure WebClient service is set to Automatic;

4. When mapping a drive, make sure ‘Reconnect sign-in’ and ‘Connect using different credentials’ boxes are ticket (make sure to use Office 365 email and password in the credentials prompt);

(you’ll be prompted twice for the username and password, make sure you fill it in twice and twice select remember credentials)

5. Go to Internet Explorer settings – Tools, Options, Connections, LAN Settings, uncheck ‘Automatically detect Settings’ – this will significantly improve the connection to sharepoint.

 

I hope this helps!
