MS Office 365 Business Premium - Outlook

[nigelot]

Hi

Really hoping somesome can help.

We use MS Office 365 Business Premium - Outlook with imap and Gridhost.

365 Outlook for Mac works perfectly.

365 Outlook for W7 (same imap as above) will Send e-mails but does not receive e-mails.

Crazy that the MS software on a Mac works seemlessly but not on Windows.

Tried to get help from our email hoster, MS Office Support and a MS Certified Office consultant.
Spent many hours now without success to fix Receive issue.

All imap setting checked and rechecked, tried on 3 W7 PCs still won't Recieve e-mails

Really appreciate anyones help

Thanks
