# Office 365

## Prerequisites

1. An active Office 365 Exchange-Online mailbox. (This sync does not work directly with any Outlook mail account, it needs a Microsoft-hosted Office 365 or Outlook.com account)
2. (sometimes) Domain Administrator approval to grant tiny+ permissions to your Microsoft account. This will depend on how your mail server and Active Directory permissions have been configured.

## Connecting your tiny+ account to Office 365

In tiny+, click on the settings cog in the top right, and select *User Settings*. From the left side menu, select *Linked Accounts*. Then select **sign in** (pictured below). You will be taken through a Microsoft authentication process; where you will also be asked to grant tiny+ permission to access your mail account.

## Performing an initial Contacts sync

Navigate back to *User settings* -> *Contacts Sync*.&#x20;

With your Office 365 account connected, you can now perform an **initial sync**. Depending on the number of contacts associated with your account this may take several minutes.&#x20;

Performing an initial sync will create a new subfolder in your Outlook contacts called ‘tiny+’. Any new contacts added to this folder will be synchronised with tiny+, and any new contacts associated with your user in tiny+ will be sent to this Outlook folder.&#x20;

## Sync options

Once you’ve performed the initial sync, your contacts will remain in two-way sync. Changes made in one system may take a few minutes to appear in the other. You can also manually perform a sync in either direction using the controls on the *User Settings* -> *Contacts Sync* page (pictured).

## Disabling / deleting the sync

If you would like to turn off the sync, you can use the **Delete this sync** button on the *Contacts Sync* page. Note that this will **not** delete the contacts either in Outlook or tiny+, and you should do this yourself if you need to.&#x20;

## Calendar Sync

{% hint style="info" %}
As of November 2019, our Calendar integration is one-way only, from tiny+ to Office 365.&#x20;
{% endhint %}

Once you have connected your tiny+ account to Office 365, you can also enable a sync of calendar items, such as Tasks, Meetings and Events.&#x20;

1. Navigate to *User Settings -> Calendar Sync*.
2. Choose *Enable Sync*.
