From the Windows Phone site:
Resetting your Windows Phone will return it to the same state it was
in the first time you turned it on. All your personal content will be
erased, and the phone will be restored to its factory settings.
If you decide to reset your phone, you can back up apps, text messages,
photos and more to your Microsoft account ...
Since Messenger is being retired I doubt it.
Messenger is being merged with Skype, under the Skype name now. So you could download the Skype app.
Here is an email (dated January 10, 2013) I got from Microsoft:
We are retiring the existing Messenger service globally (except for
mainland China where Messenger will continue to be available) ...
The purchase you made in Windows Phone Store are not the same as the Windows Store.
If you bought an app for Windows Phone 7 and it is available for Windows Phone 8 um don't need to purchase again but with Windows 8 this is not possible.
Some games can implement a mechanism where you don't need to buy in both stores but I only saw this once. It is not a ...
I think that with Windows Phone 7, you don't need a special app for Windows Live Messenger chat, because this channel was integrated into OS.
You can go into Settings->email+accounts->add an account and add your Live account here (if it is not already there). And then you go into Messages and slide the pivot screen to the left or right. There you see your ...
Not sure if you can fix this on your phone, but try the following:
Go to https://people.live.com
From the top menu, select Manage → Clean up contacts
Mark all the duplicate contacts you want to merge and click "Clean up"
Your @live account is being shown as it's the first Microsoft Account you have added to your phone. Changing the primary account can only be done after a hard reset. For this, navigate to Settings -> about and hit the "reset your phone" button and confirm.
You can't unsync them, but you can filter them. Go to Settings > Applications > People and click "filter my contact list". There you can select the sources from where your contact list will be populated.
The other option is to merge contact data from different sources, but it can be a bit tedious if you have lots of them.
Open Windows Live Mail.
Click Contacts folder, click Export button and select comma separated values (.CSV).
In the CSV Export window click browse and select the Desktop folder.
Type WLMContacts in the file name and then click the Save button.
Click Next and select all the fields that you want to export, click Finish button and wait for the export process to ...
Microsoft has its own cloud service, called Onedrive, which was also formerly known as SkyDrive during the Windows Phone 7 days. Every Windows Phone device. by default backs up pictures in the Camera Roll, Screenshots and Saved Pictures onto the cloud:
Visit onedrive.live.com and sign in with the Microsoft (Outlook, Live, Hotmail) account that you used on ...
It turns out I was running an out-of-date 8.0 build; I'm not sure when app lists / settings started to be included in backups but I'm pretty sure from what I've played around with that the build I had didn't do it. I'm currently running the latest version of 8.0 and app lists / settings are included.
Did you explicitly add your accounts to the Phone ?
Settings>>email+accounts>>add an account
Once you add the account, you can choose what to sync ... Email, Contacts & Calendar.
I have 2 laptops (Office 2013) and my Phone (Icon) in sync with my Office 365 E3 account - Contacts and Calendar (not email at this time).
If I make any change on the laptops, ...
Just imagine if someone steals your phone. They'd have access to everything even if they did know your code! That's not good and therefor you're unable to access the data on a locked phone.
On your next phone, enable backup to OneDrive before you do anything else!
The short answer is no.
Because of the architecture of Windows Phone, you can perform certain things with your primary account that you can not do concurrently with the non-primary accounts.
Potentially, in the future, this may be something that is possible with Windows Phone 8.
Otherwise, your only option is to hard reset the phone, make your wife's ...
As already mentioned, Live Messenger is on it's way out, and it's already integrated into WP7.5
However, there was a third-party Live Messenger app available before 7.5 came out, called "Messenger by Miyowa". I just checked, and it's still on the marketplace.
You can not sync contacts selectively. Either you sync all contacts or none. So I see two options:
Create a second live account and move the contacts there
Create a group where all contacts are in want to have on the phone. That group will get synced to the phone and you can just look at this group
Both options are not very convenient but currently the ...
