Readers have been pinging us for the last few hours complaining of issues with their Outlook.com email. It appears they are far from alone, and Microsoft has acknowledged the issue on their status page.
The good news that the problem has already been identified and fixed, and we should expect the issue to be resolved in short order.
We had a tip from a reader that the Windows Phone 7.8 update appears to have been causing issues with contact synching with Outlook.com, with the main issue appearing to be that contacts that are modified or added using the web interface of Outlook.com is not synching back down to the device. From searching around the net it seems to be a relatively prevalent issue.
To see if your device is affected:
Open contacts on outlook.com
Edit any contact detail of a randomly picked contact
Go to People Hub settings
Scroll down to accounts
Press and Hold Live account
Wait until sync complete
Check People Hub
If the contact does not appear you may also be afflicted.
