Every member is able to read and send email messages to and from the shared mailbox itself. Shared mailboxes are widely used. They permit performing a wide range of coordinated activities with a team. Essentially, a shared mailbox acts as a centralized service allowing many people to work in a synchronized manner.<\/p>\n<h3><em><a class=\"track-link\" href=\"https:\/\/www.sherweb.com\/partner-guide\/registration\/\">Want to see how a Sherweb partnership sets you up for success right from the start?

See if the issue persists.<\/p>\n<p>&nbsp;<\/p>\n<h3>2) Rename the Offline Outlook Data File (.ost)<\/h3>\n<p>Office 365 keeps your mailboxes (shared or individual) on a server called Microsoft Exchange. However, Outlook locally caches all folders to which you have access (also for shared mailboxes) in a file called <strong>Offline Outlook Data File (.ost)<\/strong>.<\/p>\n<p>The Offline Outlook Data File (.ost) is a synchronized local copy of your mailbox saved on your computer, and is stored in the following default location (which might vary depending on the client version and the Outlook account type): <strong>C:\\Users\\&lt;username&gt;\\AppData\\Local\\Microsoft\\Outlook<\/strong><\/p>\n<p>The Offline Outlook Data File, however, can get corrupted or become unreadable from within Outlook. Reasons for this could include a data storage device failure (bad sectors on the hard disk); networking connection failure (if the network connection has a problem, then the synchronization process will be aborted and the OST file is likely to get corrupted); incorrect file system recovery; or viruses.<\/p>\n<p>When this happens either the shared mailbox or your main Inbox might stop syncing.<\/p>\n<p>Very often mailbox synchronization issues with Outlook are due to .ost file corruption and can be resolved simply by renaming the .ost file or by creating a new Outlook profile, which will create a new Offline Outlook Data File (.ost) for Outlook to cache data.<\/p>\n<p>Navigate to: C:\\Users\\&lt;username&gt;\\AppData\\Local\\Microsoft\\Outlook, select the Offline Outlook Data File and rename it (for example, by adding \u201c.old\u201d to the end.)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11442 aligncenter\" src=\"https:\/\/www.sherweb.com\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File.png\" alt=\"Offline Outlook Data File\" width=\"1226\" height=\"595\" srcset=\"\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File.png 1226w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File-300x146.png 300w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File-768x373.png 768w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File-1024x497.png 1024w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Offline-Outlook-Data-File-600x291.png 600w\" sizes=\"auto, (max-width: 1226px) 100vw, 1226px\" \/><\/p>\n<p>Restart Outlook and check if the issue persists.<\/p>\n<p>Outlook should create a new Offline Outlook Data File, which will start to synchronize again with the Mailbox on the Exchange Server. Of course, full synchronization might take a while, and some data (emails) might be available on Outlook (especially older items) only a few hours later.<\/p>\n<h3>3) Enable\/Disable Cached Exchange Mode<\/h3>\n<p>The feature Cached Exchange Mode is set up by default when you are using an Exchange account. It works by keeping a copy of your mailbox locally saved (cached) on your computer.<\/p>\n<p>Accessing a local copy allows access to your data to be much quicker, and allows you to work on Outlook while offline.<\/p>\n<p>Using Cached Exchange Mode, you can read and respond to your cached messages while offline, and any new messages or updates to your mailbox on the server will be automatically sent\/received once Outlook (specifically the .ost file) gets connected again.<br \/>\nIf the shared mailbox is not synchronizing, you might try to disable, restart Outlook, and re-enable again Cached Exchange Mode on the advanced profile configuration settings of your Outlook profile.<\/p>\n<p>Click <strong>File<\/strong> &gt;<strong> Account Settings<\/strong> &gt; <strong>Account

The user experience is similar to Microsoft Outlook but it doesn\u2019t need the client software (Outlook) to be installed on the PC. This allows us to access e-mail, calendars, contacts, tasks, and other mailbox content when something is wrong with Outlook.<\/p>\n<p>Just go to https:\/\/login.microsoftonline.com, provide your credentials (Outlook email address and password) and log in.<\/p>\n<p>Click on the upper right user icon, and select \u201cOpen another Mailbox\u201d.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11455 aligncenter\" src=\"https:\/\/www.sherweb.com\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox.png\" alt=\"Check Shared Mailbox\" width=\"1915\" height=\"613\" srcset=\"\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox.png 1915w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox-300x96.png 300w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox-768x246.png 768w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox-1024x328.png 1024w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Check-Shared-Mailbox-600x192.png 600w\" sizes=\"auto, (max-width: 1915px) 100vw, 1915px\" \/><\/p>\n<p>Insert the shared mailbox email address.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11456 aligncenter\" src=\"https:\/\/www.sherweb.com\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address.png\" alt=\"Insert the shared mailbox email address\" width=\"1710\" height=\"657\" srcset=\"\/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address.png 1710w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address-300x115.png 300w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address-768x295.png 768w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address-1024x393.png 1024w, \/blog\/wp-content\/uploads\/Outlook-Shared-Mailboxes-How-to-Use-and-Configure-Them-Insert-the-shared-mailbox-email-address-600x231.png 600w\" sizes=\"auto, (max-width: 1710px) 100vw, 1710px\" \/><\/p>\n<p>Click on Open.<\/p>\n<p>If the Mailbox is available and properly synchronizing via Outlook Web App, this means that the issue is local, with Microsoft Outlook, and you will need to investigate further.<\/p>\n<p>If the shared mailbox is neither accessible nor properly synchronizing on the web app, the problem most likely needs to be fixed at the server level.
