Symptoms
By default, if a Microsoft Outlook 2010 or later versions profile is configured in Cached mode and you add another user's mailbox or shared folder to your profile, all items in all the folders to which you have access in the shared mailbox are downloaded to your local cache. This is a change from Microsoft Office Outlook 2007, in which only shared non-mail folder items are cached by default.

Outlook for Mac does not support Auto-mapping of shared mailboxes. A folder is shared with you If another user has shared an inbox, primary calendar folder, or primary contact folder with you, use this method to open the user's folder.
For example, the following figure shows the shared Inbox folder of Marcelo Santos. This Inbox folder is being cached in Outlook 2010 because the status bar displays Connected when this folder is selected in the navigation pane.
Cause
This problem is caused by a change in the default shared folder caching behavior that was introduced in Outlook 2010 and persists in later versions of Outlook.
Resolution
To change the shared folder caching behavior in Outlook 2010 or later versions to match the default behavior in Office Outlook 2007, you must add the following registry data to your Outlook client. In this situation, only non-mail folders such as the Calendar, Contacts, and Tasks folders are cached.
Key:
HKEY_CURRENT_USERSoftwareMicrosoftOffice<xx.0>OutlookCached Mode
or
HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice<xx.0>OutlookCached Mode
Note The <xx.0> placeholder represents your version of Office (16.0 = Office 2016, Office 2019, or Outlook for Office 365, 15.0 = Office 2013, 14.0 = Office 2010). Antivirus software for nokia phone free download.
Name: CacheOthersMail
Type: DWORD: Value: 0
Note
If you configure the registry value in the
Policies registry key, the change is applied to all existing Outlook profiles. If you configure the registry value in the non-Policies key, the change only applies to new Outlook profiles that you create.

You can use one of the following methods to configure this registry data for Outlook 2010 or later versions:
Regardless of the method that you use, if you disable the caching of shared mail folders, the Outlook status bar displays Online when you select a shared mail folder in another mailbox in the navigation pane. This is illustrated in the following figure.
In this configuration, items in mail folders are not available when you are working offline in Outlook. However, items in non-mail folders are still available when you are working offline in Outlook.
Method 1 - Manual modification of the Windows Registry
Important
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.
To change the shared folder caching behavior in Outlook 2010 or later versions to match the default behavior in Office Outlook 2007, you must add a registry value to your Outlook client. To do this, follow these steps:
Note
This method only affects any new Outlook profiles that you create. To change the behavior for all existing Outlook profiles, add the registry value in the following registry key path:
HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice<xx.0>OutlookCached Mode
The <xx.0> placeholder represents your version of Office (16.0 = Office 2016, Office 2019, or Outlook for Office 365, 15.0 = Office 2013, 14.0 = Office 2010).
Method 2 - Configure the registry by using a Group Policy setting
The registry key value that is required to change the default shared folder caching behavior in Outlook 2010 or later versions can be configured by using a Group Policy setting
Outlook 2013 or later versions
The default Group Policy template files for Outlook contain the policy setting that controls this functionality. These are Outlk16.admx and Outlk16.adml for Outlook 2016, Outlook 2019 and Outlook for Office 365 and Outlk15.admx and Outlk15.adml for Outlook 2013.
To deploy this setting by using the Outlook Group Policy template, follow these steps:
After you run this command, start Registry Editor on the client workstation to make sure that the
CacheOthersMail registry value exists on the client, and that it has a value of 0:
Key: HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice<xx.0>OutlookCached Mode
Note The <xx.0> placeholder represents your version of Office (16.0 = Office 2016, Office 2019, or Outlook for Office 365, 15.0 = Office 2013).
Name: CacheOthersMail
Type: DWORD: Value: 0
If you see this registry data in the registry, the Group Policy setting was already applied to this client. Start Outlook 2013 to verify that this change is implemented.
Outlook 2010
The default Group Policy template (Outlk14.adm) for Outlook 2010 does not contain the policy setting that controls this functionality. Therefore, you must use a custom Group Policy template to manage this functionality.
To deploy this setting by using a custom Group Policy template, follow these steps:
After you run this command, start Registry Editor on the client workstation to make sure that the CacheOthersMail registry value exists on the client, and that it has a value of 0:
Key: HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice14.0OutlookCached Mode
Name: CacheOthersMail
Type: DWORD: Value: 0
If you see this registry data in the registry, the Group Policy setting was already applied to this client. Start Outlook 2010 to verify that this change is implemented.
Method 3 - Deployment of the Shared Mail Folder Cache setting using the Office Customization Tool
You can use the Office Customization Tool (OCT) to deploy the Shared Mail Folder Caching setting.
Outlook 2013 or later versions
To deploy this setting in Outlook 2013 or later versions, use the Office Customization Tool (OCT) built-in setting. To do this, follow these steps:
Note
You must have an enterprise edition of Microsoft Office to use the OCT. If you have a Retail edition of Office, you receive the following error when you try to start the OCT:Files necessary to run the Office Customization Tool were not found. Run Setup from the installation point of a qualifying product.

Download Shared Folders Outlook
Name: DownloadSharedFolders
Type: DWORD Value: 0 Effect on the size of the Offline Outlook Data (.ost) file
If Outlook is configured to download shared folders, the contents of the shared folders are stored in your local Offline Outlook Data (.ost) file. If the shared folders contain many items or large attachments, your .ost file size may grow significantly.
Additionally, Outlook 2013 introduced support for Site Mailboxes. The Site Mailboxes feature requires Exchange Server 2013 or later versions and SharePoint 2013 or later versions. If you are working in one of these environments and are granted permission to a site mailbox, the site mailbox is automatically added to Outlook 2013 or later versions. If you have Download Shared Folders enabled, the site mailbox contents are synchronized to your local .ost file. This can result in a significantly larger .ost file.
For more information about large Outlook data files and performance, see You may experience application pauses if you have a large Outlook data file.
If the size of your .ost file is restricted by policies, caching shared folders may result in the .ost file size limit being reached. For more information about policies that administrators may use to limit the size of Outlook data files, see How to configure the size limit for both (.pst) and (.ost) files in Outlook.
