It contains all the old and unused or less-used mailbox emails and frees up the space in the primary mailboxes. With the new AutoArchive feature, users can now even set retention policies and transfer data at regular intervals. The In-place Archive not showing in Outlook 2019 or any other version is thus critical and needs immediate resolution with the free methods and the paid tool explained here.\u00a0<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Free_Fix_Exchange_Online_Archive_Mailbox_Not_Visible_in_Outlook\"><\/span>Free Fix Exchange Online Archive Mailbox Not Visible in Outlook<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This part elaborates on the manual troubleshooting you can try to fix the disappearance of the online archive folder. These are:<\/p>\n<h4>1) Microsoft Support and Recovery Assistant\u00a0<\/h4>\n<p>Accessing online archive mailboxes of other users? Use this to scan Outlook and find the issues with advanced diagnostics of the configurations. Steps are:<\/p>\n<ol>\n<li aria-level=\"1\">Download the <strong>tool<\/strong> and initiate the scan.\u00a0<\/li>\n<li aria-level=\"1\">Then, it prompts to opt for a problematic app. Choose <strong>Advanced Diagnostics.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">Click <strong>Next<\/strong>, pick <strong>Outlook<\/strong>, and again click <strong>Next.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">Further, it prompts if you are <strong>running the application on the same system<\/strong>. Click <strong>Yes.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">Input the details of the <strong>Exchange Online Archive Account<\/strong> and click <strong>Next.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">Afterward, <strong>validate<\/strong> your account credentials and<strong> run the scan<\/strong>. Wait for it to complete.\u00a0<\/li>\n<li aria-level=\"1\">The detailed report after the scan with all errors appears. You can check the complete configuration summary too. Tap <strong>Next.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">Complete and follow the on-screen instructions to recover the Exchange Online Archive mailbox missing in Outlook.\u00a0<\/li>\n<\/ol>\n<h4>2) Verification of Full Access Permissions\u00a0<\/h4>\n<p>The administrator needs to assign the complete permissions so that both primary and archive mailboxes can be accessed easily in Outlook Web App and desktop Outlook. The steps for it are:<\/p>\n<ol>\n<li aria-level=\"1\">In <strong>EAC<\/strong>, go to the<strong> Recipients <\/strong>tab, and you\u2019ll find three options: <strong>Mailboxes, Resources, <\/strong>and<strong> Shared.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Then, select <strong>Mailboxes<\/strong> and opt for the one you need complete permissions for. Tap the <strong>Edit<\/strong> icon.\u00a0<\/li>\n<li aria-level=\"1\">The <strong>Mailbox Properties<\/strong> page shows up. Here, move to <strong>Mailbox Delegation<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">Within it, you get three options to choose from, i.e., <strong>Send As, Send on Behalf, <\/strong>and <strong>Full Access.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Opt for <strong>Full Access<\/strong> and, within it, select the mailbox for which permissions are needed. Press <strong>Save &gt;&gt; OK.<\/strong><\/li>\n<\/ol>\n<h4>3) Check Your Availability of Account Licence\u00a0<\/h4>\n<p>Accessing the Online Archive Mailbox in Office 365 requires the Office 365ProPlus Licence. To verify whether you have it or not, follow these steps:<\/p>\n<ol>\n<li aria-level=\"1\">Go to <strong>Microsoft 365 Admin Center<\/strong>, open it, and <strong>log in<\/strong> to your account.\u00a0<\/li>\n<li aria-level=\"1\">Next, from left, click <strong>Billing<\/strong> and within it, move to <strong>Licences<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">All the available and assigned licences will appear here.\u00a0<\/li>\n<li aria-level=\"1\">Or, you can go to <strong>Users <\/strong>and <strong>Active Users<\/strong> to verify their <strong>Licences.\u00a0<\/strong><\/li>\n<\/ol>\n<h4>4) Ensuring MS Outlook is Up-to-Date\u00a0<\/h4>\n<p>Exchange Online archive not showing can also be if your Outlook version has expired. So, it must be updated instantly with the following steps:<\/p>\n<ol>\n<li aria-level=\"1\">Open <strong>Microsoft Outlook<\/strong> and from the <strong>File<\/strong>, click <strong>Office Account<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">Then, in the <strong>Office Updates<\/strong>, expand the <strong>Update Options<\/strong> menu.\u00a0<\/li>\n<li aria-level=\"1\">Afterward, click <strong>Update Now,<\/strong> and if any are available, install them.\u00a0<\/li>\n<\/ol>\n<h4>5) Turn Off Automatically Detect Settings\u00a0<\/h4>\n<p>The browser proxy settings, if remained turned on, can also lead to the Exchange Online Archive Mailbox Missing in Outlook. Hence, you need to switch it off with the steps below:<\/p>\n<ol>\n<li aria-level=\"1\">In <strong>Microsoft Edge<\/strong>, tap the <strong>three-dot icon<\/strong> in the upper-right and choose <strong>Settings.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Next, in the <strong>search bar<\/strong>, input <strong>Proxy settings<\/strong> and click <strong>Enter.<\/strong>\u00a0<\/li>\n<li aria-level=\"1\">From the list, click on <strong>Open your computer\u2019s proxy settings, <\/strong>and a dialog appears.\u00a0<\/li>\n<li aria-level=\"1\">At last, under <strong>Automatically detect settings<\/strong>, turn the <strong>toggle off<\/strong> and save changes.\u00a0<\/li>\n<li aria-level=\"1\"><strong>Restart your Outlook<\/strong> to verify if the online archive mailbox appears in Outlook.\u00a0<\/li>\n<\/ol>\n<h4>6) Handling Cache Exchange Mode\u00a0<\/h4>\n<p>Even though Cache Exchange Mode is used to store local copies of the mailbox, it tends to sometimes interferes with the visibility of the mailbox. You can manage it by:<\/p>\n<ol>\n<li aria-level=\"1\">In Outlook, navigate to<strong> File <\/strong>and open <strong>Account Settings.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Then, pick your <strong>Exchange Account<\/strong> from the list and click <strong>Change<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">Further, <strong>uncheck <\/strong>the box for <strong>Use Cache Exchange Mode<\/strong> and tap <strong>Next.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Save it and<strong> restart Outlook<\/strong> to see if you can access the Online Archive.\u00a0<\/li>\n<li aria-level=\"1\">If it appears, <strong>re-enable Cache mode<\/strong> and resume the operations after Outlook restart.\u00a0<\/li>\n<\/ol>\n<h4>7) New Outlook Profile Creation<\/h4>\n<p>Corrupted profiles also restrict you from accessing the archive mailboxes. So, using these steps, you can create a new profile for data access:\u00a0<\/p>\n<ol>\n<li aria-level=\"1\"><strong>Close MS Outlook <\/strong>and from the <strong>Control Panel,<\/strong> click <strong>Mail.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Then, press <strong>Show Profiles<\/strong> and click <strong>Add,<\/strong> enter the <strong>name<\/strong>, and hit <strong>OK<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">Follow the on-screen prompts to <strong>create a new Exchange profile<\/strong>.\u00a0<\/li>\n<li aria-level=\"1\">Set it as the default with the <strong>Always Use this Profile<\/strong> option and tap <strong>OK.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Restart Outlook to resolve the Exchange Online Archive mailbox not displaying in Outlook.\u00a0<\/li>\n<\/ol>\n<h4>8) AutoDiscover Resetting by Registry\u00a0<\/h4>\n<p>The AutoDiscover feature in Outlook helps find mailboxes and archives easily. So, if it\u2019s not working properly or isn\u2019t refreshed, you can reset them. However, note that it should be performed with caution, and you should have a backup. Steps to fix Exchange Online Archive Mailbox Missing in Outlook:<\/p>\n<ol>\n<li aria-level=\"1\">Close Outlook and press <strong>Win+R<\/strong>, type <strong>regedit<\/strong> in it, and click <strong>Enter.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">Then, navigate to <strong>HKEY_CURRENT_USER\\Software\\Microsoft\\Office\\16.0\\Outlook\\AutoDiscover.\u00a0<\/strong><\/li>\n<li aria-level=\"1\">After that, create a <strong>new DWORD (32-bit) value<\/strong> and name it as <strong>ExcludeLastKnownGoodUrl.<\/strong><\/li>\n<li aria-level=\"1\">In the end, set the value to 1, reboot the computer, and restart Outlook.\u00a0<\/li>\n<\/ol>\n<h4>9) Forced Archive via PowerShell cmdlets\u00a0<\/h4>\n<p>Managed Folder Assistant helps with forcing immediate provision via cmdlets in Office 365 PowerShell. Steps are:<\/p>\n<ol>\n<li aria-level=\"1\">Connecting to the Exchange Online PowerShell:<\/li>\n\n<table border=\"1\">\n<tbody>\n<tr>\n<td>\n<p><strong>Install-Module -ModuleName ExchangeOnlineManagement<\/strong><\/p>\n<p><strong>Connect-ExchangeOnline -UserPrincipalName admin@yourdomain.com<\/strong><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n<li aria-level=\"1\">Next, for specific users, run Managed Folder, Assistant by:<\/li>\n\n<table border=\"1\">\n<tbody>\n<tr>\n<td>\n<p><strong>Start-ManagedFolderAssistant userID@yourdomain.com<\/strong><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<li aria-level=\"1\">Afterward, use the following commands:<\/li>\n\n<table border=\"1\">\n<tbody>\n<tr>\n<td>\n<p><strong>Get-Mailbox &lt;user_mailbox_ID&gt; | FL ArchiveName<\/strong><\/p>\n<p><strong>$dn=Get-Mailbox &lt;user_mailbox_ID&gt; | Select -ExpandProperty DisplayName<\/strong><\/p>\n<p><strong>Set-Mailbox &lt;user_mailbox_ID&gt; -ArchiveName &#8220;In-Place Archive -$dn&#8221;<\/strong><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<li aria-level=\"1\">Wait for <strong>5-10 minutes,<\/strong> and then your Exchange Online Mailbox will appear.\u00a0<\/li>\n<li aria-level=\"1\">At last, disconnect your Exchange PowerShell with:<\/li>\n\n<table border=\"1\">\n<tbody>\n<tr>\n<td>\n<p><strong>Disconnect-ExchangeOnline<\/strong><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"Fix_Exchange_Online_Archive_Mailbox_Not_Visible_in_Outlook\"><\/span>Fix Exchange Online Archive Mailbox Not Visible in Outlook<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If the above methods didn\u2019t seem to work and you don\u2019t have any access to your archive mailbox, then what? How will you access the crucial emails now? What if your archive mailbox contains critical primary mailbox emails and documentations, which, definitely most of the time, it does. So, in such a case, the best resort is to use professional software like the <strong>SysInfo Office 365 Export to PST Tool <\/strong>to take a backup beforehand. It is very easy to use and requires no technical expertise, unlike the manual troubleshooting tricks.
