Archive Data<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This method is useful when you want to carry almost everything, except contacts, with you in a PST. You can email contacts separately. To archive items, perform the steps below if you are using Outlook 2007 or above:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Step 1<\/strong>: Open Outlook.<\/li>\n\n\n\n<li><strong>Step 2<\/strong>: Select Folder &gt; AutoArchive Settings<\/li>\n\n\n\n<li><strong>Step 3<\/strong>: Now select the AutoArchive tab<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.filerepairtools.com\/tips\/wp-content\/uploads\/2017\/06\/auto-archive-mails-in-outlook-2016.jpg\" alt=\"convert ost to pst\" class=\"wp-image-757\"\/><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Step 4<\/strong>: Select Archive this folder using these settings.<\/li>\n\n\n\n<li><strong>Step 5<\/strong>: In the drop-down, select <strong>days&nbsp;<\/strong>and enter a day in the&nbsp;<strong>Clear out items older than<\/strong><\/li>\n\n\n\n<li><strong>Step 6<\/strong>: Select Move old items to default archive folder<\/li>\n\n\n\n<li><strong>Step 7<\/strong>: Click the Apply button.<\/li>\n<\/ul>\n\n\n\n<p>All items will be moved into the Archive folder<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Create_a_New_PST_And_Move_Data_In_That\"><\/span>Create a New PST And Move Data In That<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The second option is to create a new PST from File &gt; Account Settings &gt; Account Settings &gt; New. Note the path of the New PST file.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.filerepairtools.com\/tips\/wp-content\/uploads\/2019\/05\/create-outlook-pst-file.jpg\" alt=\"create outlook pst file\" class=\"wp-image-1895\"\/><\/figure>\n\n\n\n<p>Once the PST is created, select all the data that you want to carry with you and drag it into the new PST file.

Send via Email<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Another possible option is a bit tedious and time-consuming, but you may want to use this method in case the items to be transferred are few. You can forward\/email the important emails, contacts, etc to your personal email ID from your official email ID. However, ensure that your company policy allows the same.<\/p>\n\n\n\n<p>If there are many items, then right-click each item and save it in Outlook format. Once all items are saved, zip all of them and then forward that zip file as an attachment.<\/p>\n\n\n\n<p>And, if you want to carry the calendar entries, you can use the Forward Calendar feature in Outlook 2007 or 2010.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>While you want to carry your data with you when leaving the organization, it is a must to ensure that your company allows the same. A wrong action may lead to a problem.<\/p>\n\n\n\n<p>Note:&nbsp;Do not delete the Exchange profile<br>Until you have opened the existing OST file and saved its content in PST format, do not delete the current Exchange profile. Once the profile is deleted, you will not be able to fetch data from the OST file, and then you will be left with one of the two solutions:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Restore Exchange Account<\/strong>: This method may be helpful only when your system has a restore point; otherwise not.<\/li>\n\n\n\n<li><strong>Use Third-Party Convert OST to PST Tool<\/strong>: It helps you to convert OST to PST and get access to the data stored in the OST file.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Restore_an_Exchange_Account\"><\/span><strong>How to Restore an Exchange Account<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>In order to restore the deleted Exchange account, you need to look for the restore point and restore your system to that point.
