+## Microsoft Teams Notifications
+* **Source**: https://teams.microsoft.com
+* **Icon Support**: Yes
+* **Message Format**: Markdown
+* **Message Limit**: 1000 Characters per message
+
+### Account Setup
+Create a free account at https://teams.microsoft.com.
+
+You will need to create an **Incoming Webhook** to attach Apprise.  This can be accomplished through the **the app store** (bottom left hand side of slack like interface); don't worry it's free. From within the app store, search for **Incoming Webhook**. Once you click on it you can associate it with your team. You can also assign it a name, and an avatar. Finally you will have to assign it to a channel.
+
+When you've completed this, it will generate you a URL that looks like:
+```
+https://outlook.office.com/webhook/ \
+       abcdefgf8-2f4b-4eca-8f61-225c83db1967@abcdefg2-5a99-4849-8efc-\
+        c9e78d28e57d/IncomingWebhook/291289f63a8abd3593e834af4d79f9fe/\
+          a2329f43-0ffb-46ab-948b-c9abdad9d643
+```
+Yes... The URL is that big...  but at the end of the day, it looks like this (greatly simplified)
+
+This effectively equates to:
+```https://outlook.office.com/webhook/{tokenA}/IncomingWebhook/{tokenB}/{tokenC}```
+
+Hence:
+```
+https://outlook.office.com/webhook/ABCD@WXYZ/IncomingWebhook/DEFG/HIJK
+                                       ^                      ^    ^
+                                       |                      |    |
+  These are important <----------------^----------------------^----^
+```
+
+So as you can see, we have is 3 separate tokens.  These are what you need to build your apprise URL with. In the above example the tokens are as follows:
+1. **TokenA** is ```ABCD@WXYZ```
+2. **TokenB** is ```DEFG```
+3. **TokenC** is ```HIJK```
+
+### Syntax
+Valid syntax is as follows:
+* **msteams**://**{tokenA}**/**{tokenB}**/**{tokenC}**/
+
+### Parameter Breakdown
