The default Yahoo account settings under settings > email+accounts on Windows Phone does not support Contacts or Calendar syncing, so those items are not synced to a phone when the account is created… the only thing that syncs is email.
But if you also use Yahoo Contacts and Calendar, there is a workaround….which I have tested on my own (hardly ever used) yahoo account.
Syncing Yahoo Email to the Phone
To sync your Yahoo email, you’ll set up an “email only” account.
On the phone select Settings > email+accounts.
Tap “add an account” > select the “Yahoo! Mail” option.
Input your Yahoo email address and password in the spaces provided. This account will sync your email to the phone.
Syncing Yahoo Contacts & Calendar to the Phone
The yahoo mail only account you created above will NOT sync any contacts or appointments that are stored in your Yahoo account to the phone. You’ll need to create another account the sync this data.
When you turn on a brand new Windows Phone for the first time, you will be prompted to create a Microsoft Account on it. [See the article entitled, “What is a Microsoft Account?” to learn about the fundamental ways that the Microsoft Account is used on a windows phone.]
If you already have a Microsoft-related account that you use, you don’t need to create a new account. You can use the username (which is an email address) and password of your preferred Microsoft-related account when you create the Microsoft Account on the phone.
When you create the Microsoft Account on the phone, you may notice that the only data that can be selected to sync under the “Content to sync” heading is Email, but if you set up a secondary hotmail.com, live.com, or outlook.com account on the phone, you will find options to sync Email, Contacts, Calendar, and Tasks under the “Content to sync” heading.
You can view and work with Office 2013 files (Word, Excel, PowerPoint and OneNote) from your Windows Phone by opening up the Office Hub on the phone.
The Office Hub “places” screen is where you can access the folders and documents that are stored on your phone, any email attachments received to your Microsoft email account that you’ve opened on the phone, and all the folders and documents that are stored on your OneDrive or Office 365 (sometimes referred to as sharepoint) accounts.
When you access the OneDrive place through the Office Hub, you will also be able to access any folders and files that have been shared with your OneDrive account from another OneDrive account.
The Office Hub “recent” screen, which you can view by swiping over to the right is where you can create new documents and search for documents that are stored on the phone, as an opened email attachment, on your OneDrive or Office 365 account or across all four places.
Pairing a Windows Phone to another Bluetooth enabled device is pretty easy to do, but you might be disappointed when you do it. When I got my first Windows Phone – a Samsung Focus (WP7) – one of the first things I tried to do was pair it with my Bluetooth keyboard. The phone paired just fine, but nothing I typed on my keyboard showed up on my phone. After researching the problem I realized that the phone was missing the HID profile, which it needed to know what to do with the keyboard after the pairing was achieved!
Bluetooth profiles possess the “capabilities” that enable a Bluetooth connected device to interpret and act on the commands received from another Bluetooth connected device. In order for the Bluetooth radio in a receiving device to translate and act on the commands sent from another Bluetooth device, it must possess a compatible profile as the sending device.
The Samsung Focus does not include the Bluetooth HID profile (Human Interface Device) that would enable it to connect to and use external devices like mice or keyboards…..and unfortunately even today the latest Windows Phone 8.1 devices do not include this profile so I still can’t use my bluetooth keyboard with my phone.
Windows Phone 8 uses Hubs and application sandboxes to store and access user files. You can browse and access the files that are stored on the phone by accessing the hub or app that is used to view and work with the file. Files that are stored on a phone must be associated with a Windows Phone app (native or third party) and files are stored in the associated [opening] app’s hub or “sand box.”
Windows Phone 8 can receive and store files that are shared with it from another Bluetooth connected device. Bluetooth shared files are stored in one of the hubs on the phone or in a compatible app’s sandbox.
Receiving Shared Files via Bluetooth
When a Bluetooth-enabled device shares a file with your Windows Phone, you’ll be prompted to “accept” or “ignore” it (in this example, my laptop which is named AVALON48 is sharing a file with my Nokia Lumia 920).
OneDrive is Microsoft’s cloud-based data repository and every Microsoft account includes a minimum of 15 GB of free OneDrive space. You can manually upload files to your OneDrive space or you can install Microsoft’s OneDrive app on your Mac, Windows computer, laptop, tablet or phone and sync files between your online OneDrive space and all your devices (there are compatible apps for Windows-, Android- and iOS-based devices).
Your OneDrive space can be your own private data repository or you can use it to collaborate with your friends, family members, clubs, groups, coworkers, or customers by sharing your OneDrive folders and files with other people. When you share folders or files with others, you also set permissions that define how the shared files can be accessed by others. You can grant permission to others to only view the files or you can grant permission to view and edit the files.
Enabling two step verification on your Microsoft Account creates a password recovery code that you’ll need to use if you ever need to recover your Microsoft Account password. Enabling two step verification on your account will also require you to change the password that you use on your phone to a unique security code, also referred to as an app password. You will no longer be able to use the password that you use to log into your account on a computer as the password on your phone (or some of your other devices).
Using a different Microsoft account on a Windows Phone is not desirable for the following reasons:
The only way to switch to a different Microsoft Account on a Windows Phone is by hard resetting the phone and setting it up again under the different Microsoft Account. A hard reset wipes all your user files and data from the phone, including:
All Contacts and related contact history
All Calendar items
Any paid or free apps
Sent & received email
Any PDF files that are stored on the phone
All Office-related documents that are stored on the phone
Pictures (camera roll and albums)
All user-defined accounts & settings (email accounts, wifi settings, bluetooth connections
Much of this data is synced between the phone and its related Microsoft Account, so a hard reset won’t permanently delete it since the data is stored on the Microsoft Account. But setting a phone up under a different Microsoft account means you:
