I have Windows 8 and problem started 2 days ago.
Swipe in from the right edge of the screen, and then tap Search.(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.)
Enter Control Panel in the search box, and tap or click Control Panel.
Enter Recovery in the Control Panel search box, and then tap or click Recovery.
Tap or click Open System Restore, select a date before this issue and perform the restore.
Josh, I've done as suggested but nothing has improved. I have however, updated just now to Windows Live essentials 2012 from 2011 version.
Still cannot open Windows Live Mail ...still same error message "0x8000cccoF" IMAP command could not be sent to the server "
What do you suggest now ?
Josh, I'm still not able to send & receive emails via Windows Live Mail
and if I click on "Recovery" I will have to install loads of programmes again and I risk losing my email history in folders.
Is there not a way to clean or re-set IMAP commands ?
My internet service provider is BT who I mentioned earlier I contacted about this email problem and their technical guy took remote control of my PC to check it over and found all systems and programmes running okay. They concluded that Microsoft Windows Live Mail had been corrupted.
So I'm not sure where to go apart from calling in a local PC expert to make a house call.
I do not want to risk losing my email history and stuff in storage folders within WLM ...I am guessing that should I "uninstall" WLM I will lose the contents and they will not re-appear on re-installing.
Do you have any experience of doing this successfully before Josh ?
I'm sorry but your advice did not work. But I have since had the problem solved by a local IT expert who found my IMP settings would not connect to the BT server and changed them to POP3 which then worked and cleared everything with my WLM which is now back to normal.
My wife who shares the same PC had not suffered the same issue...so we have not lost any of our stuff in storage folders which we would have done if we followed your advice.
It would appear the problem was generated by BT Mail during their systems transition to Yahoo Mail.
