Maximum number of devices allowed to use the same Outlook account - outlook

What's the maximum number of devices that can use an Outlook account at the same time?
I need to keep an Office365 user logged in (for months) on 7 tablets at the same time plus sporadically access it from a browser.
Context:
I'm developing and Android application, based on outlook-sdk-android, that talks with the Outlook Calendar REST Api. The app uses an Office REST Client for Android (a shared client stack provided by orc-for-android) .
Thanks

AFAIK,the Exchange(thats where the calendar function is accessible) ActiveSync device limit is 100. Here is a reference:
Exchange Online Limits

I've tried to login 15 times the same user on the same device and it worked.
Tried to login on 6 different emulators at the same time + 2 real devices and worked.

Thingworx client for windows 10

I want to gather some information from a windows 10 machine over the internet using the thingworx platform.
Here's a scenario:
Admin logs into thingworx app
Exisiting or new computer (windows 10 ) is added (serial number computer)
Thingworx platform creates a thing based on a created template
User receives application key which will be entered on a client which is installed on the computer
Client is started based on event and sends data to thingworx platform
Communication is secured
Is there a best practice or even a client available / open source or Licence based which relieves the headache of security etc.?
Yes, alwaysOn is used mostly as web socket protocol for communication between devices & ThingWorx platform. Apart from these one case also use MQTT.
If you want to use for Demo/Academic Purpose then use Thingworx Academic Simulator. I have been using it for Testing many scenarios.

Why do whatsapp web application needs phone connection all the time?

WhatsApp just announced a new web application see here.
For some reason, the interface requires the phone to be connected all the time. Is it for performance reasons (not to create additional load on their current servers)? Is there any other constraint that cause that?
The official explanation:
Your session on WhatsApp Web is an extension of WhatsApp on your
phone. WhatsApp Web connects to your phone to sync messages, thus you
can see all messages on both devices. Thus, the first requirement to
being able to use WhatsApp Web is an active WhatsApp account on your
smartphone.

As you may know your Whatsapp history is only being stored in a database on the phone itself. To see that history in your web browser, it needs to get it from the phone. Whatsapp could have redesigned it, so that everything is stored in the cloud (as many competing messaging apps do). But that seems to be against their philosophy. They keep it tighly coupled to a (one) phone. As you may know you cannot install Whatsapp on multiple phones using the same account. The web interface is just a remote for Whatsapp running on your phone.
And even though I don't know for sure, I think it's more secure too. It wouldn't surprise me if the data that's sent between the web app and the phone is encrypted in a way that even Whatsapp themselves cannot decrypt. Maybe the QR code is generated client-side (in the browser) and by scanning it using the app there is no need to exchange the keys through Whatsapp's servers. That way they don't ever get the encryption keys and will not be able to inspect the data that gets routed through their servers.
Note: Of course Whatsapp could at any time change their implementation of both the app or the web app and enable eavesdropping.

How to get the current location of windows phone without running the app?

I have developed a windows phone app that sends notification to users. There is a cloud service that send notification via mspn and an app running on windows phone. My cloud service will send notification based on current location of the phone . The app running in windows phone needs to register the current location of the device on cloud service every 12 hours. My app wont be running 24hour. So how can i update the device's position after every 12 hours? Can i run my app in background? Has anyone faced a similar situation?
You can run Periodic Agent in the background. More info can be fount on MSDN:
Background Agents Overview for Windows Phone
How to: Implement Background Agents for Windows Phone
When you want use GeoCoordinateWatcher inside your background agent you have to know about some limits:
This API, used for obtaining the geographic coordinates of the device,
is supported for use in background agents, but it uses a cached
location value instead of real-time data. The cached location value is
updated by the device every 15 minutes.

Messenger connect desktop API for Windows Phone 7

Is there Messenger Connect API for Windows Phone 7 to use in Silverlight phone application to allow user authentication with windows live id and get a user consent to share profile data with my app? It all works great for PC desktop app or ASP.Net. I want the same experience for my users with the phone: login using windows live id and access the same data they can access on their desktop through a web site or desktop app. The backend is, obviously, multi-tenant, one database, many app users - everyone sees his own data based on his windows live id.
Nick Randolph demonstrated some interaction with the messenger api's here if you'd like to check it out.

Can Windows Phone 7 connect to an Exchange server to sync its contacts, calendar etc.?

Can Windows Phone 7 connect to an Exchange server that allows the phone to keep its contacts, calendar etc. in sync?
Thanks!
Yes, it can connect to an Exchange server and sync emails, contacts and calendar. If you are looking at doing this in your WP7 application, you will have write your own code to connect and sync various items. There is no API method or class that will help you build your WP7 application to sync items from an Exchange server. You will be able to use email or phone number chooser task to select items from your contacts. You may also send an email from your app. Currently, an app can't interact with the calendar.
