You can sync your Outlook data with mobile devices and with other applications. Outlook also syncs regularly with Microsoft Exchange account accounts and e-mail accounts. The descriptions below provide details about how Outlook syncs information.

Exchange

When you use a Microsoft Exchange account in Outlook, your e-mail messages, contacts, calendar events, and any other Microsoft Exchange folders are synchronized automatically. Your information is always up to date in Outlook and on the server that is running Microsoft Exchange Server.

Microsoft Exchange accounts

The following table lists the Outlook items that synchronize and do not synchronize with the Exchange server.

Outlook item

Exchange server

Messages

All Exchange folders, including subfolders, can be accessed by using Outlook, and Outlook is continually synchronized with the Exchange server automatically. Outlook completes a check for new messages on the server once every minute.

Rules

If you have a Microsoft Exchange account managed by Microsoft Exchange Server 2010 or later, you can use Outlook for Mac to create and edit rules that are saved on the Exchange server. You cannot view or edit rules that are set to run only in Outlook for Windows.

With a Microsoft Exchange account managed by Microsoft Exchange Server 2007, you cannot use Outlook for Mac to edit or create rules that are saved on the Exchange server (such as rules you created in Outlook for Windows). Rules that you create in Outlook for Mac are saved on your computer and run on messages only as they are synchronized with Outlook for Mac. For more information, see Create a rule in Outlook for Mac 2016.

Contacts

All Exchange account contacts and contact folders in Outlook are continually synchronized with the Exchange server automatically.

However, Contact Groups/Distribution Lists saved on Outlook for Mac are not saved to the Exchange Server. Any groups that are created are saved on the computer and are available only in Outlook for Mac. The same applies for the Contact Groups saved on the Exchange Server

Calendar events

All Exchange account calendars and their events in Outlook are continually synchronized with the Exchange server automatically.

Notes

Notes and notes folders are synchronized with the Exchange server.

Tasks

Tasks and tasks folders are synchronized with the Exchange server.

Follow up flags

Messages and contacts that have been flagged for follow up are synchronized with the Exchange server, along with due dates, start dates, reminder dates, and completed dates.

Categories

Category information that you apply to items in Outlook is synchronized with the Exchange server. However, colors associated with categories may vary between Outlook for Mac and Outlook for Windows.

Your information is also available to any other applications that you use to connect to your Exchange server, such as Outlook for Windows. If you are using both Outlook for Mac and Outlook for Windows to access the same Microsoft Exchange account, you should be aware of some differences in how the two applications display information:

Type of information

Differences between Outlook for Mac and Outlook for Windows

Contacts' e-mail addresses

In Outlook for Mac, you can store up to 13 e-mail addresses in a single contact. In Outlook for Windows, you can store up to three e-mail addresses. When contacts are synchronized, Outlook for Mac synchronizes the default e-mail address with the E-mail field in Outlook for Windows. The next two addresses listed in the Outlook for Mac contact are synchronized with the E-mail 2 and E-mail 3 fields in Outlook for Windows.

Contacts' mailing addresses

Some fields, such as Middle Name, are available in Outlook for Mac but not in Outlook for Windows. As a result, if you enter information in the Middle Name field, you will not be able to see that information in Outlook for Windows. Similarly, Outlook for Windows provides fields for contacts that are not in Outlook for Mac.

To work around this issue, you can enter information in the Notes tab in Outlook for Mac, and that information is displayed in the Notes box in Outlook for Windows.

IMAP e-mail accounts

If you want to sync your IMAP e-mail, you first need to add the account to Outlook. For more information about how to add an account, see Add an email account to Outlook for Mac.

After that, there are two synchronization options: using IMAP IDLE (also known as "Live Sync") and creating schedules for subscribed folders. You can use IMAP IDLE to maintain the connection to the IMAP server and apply changes that you make to the read, unread, or flagged status of messages on the server. But you can maintain the connection to only one folder at a time. You can also create schedules that synchronize your subscribed folders in Outlook with the IMAP mail server.

You can use IMAP IDLE and schedules to perform the following actions:

Use

To

IMAP IDLE

Maintain your connection to the IMAP server for one folder.

For more information about IMAP IDLE, see IMAP account server settings.

POP e-mail accounts

If you want to sync your POP e-mail, you first need to add the account to Outlook. For more information about how to add an account, see Add an email account to Outlook for Mac.

After that, you can use schedules to set when you want Outlook to synchronize with the POP mail server by sending or receiving mail messages.

You can also set your POP account's server options to leave a copy of each message on the server, delete messages after a set number of days, or delete messages after you delete them in Outlook.

You can use schedules or server options to perform the following actions:
