Restoring Outlook Emails From an OST After Deleting the Mailbox

The complete blog provides users with a method to restore Outlook Email messages from the respective folder. It even offers users with a way to recover the deleted items when MS Outlook works in a stand-alone mode or if connected to MS Exchange Server. It even provides the users with a method to restore OST to PST file if those files are inaccessible. 

Detailed Summary- Recover Outlook Emails
Deleting the messages from MS Outlook Mailbox Folders is a problem that can occur either accidentally or intentionally. As, we all are aware that Outlook uses PST as the proprietary file format for storing large volume business and the personal data e.g. Mails, address books, calendars, journals etc. Data deletion is broadly divided to two classes: Soft Deletion, Hard Deletion. Soft deletion is also defined as if the data is deleted from any mailbox folder like Inbox, Drafts, Address Books, and Sent Items. This is called soft deletion as the data can be recovered easily and it is possible to restore Outlook Deleted Mailboxes and then put them to the deleted items folder. If the items are permanently deleted, then it is referred as Hard Deletion. Hard Deletion can be done by pressing Shift+Delete Key together. The basic question that arises is it possible to recover deleted data from Outlook Mailbox Folder? So, let’s explore the answer for this query: 

In case if data is temporarily deleted, then it can restore using following steps but the recovery method depends on the edition of MS Outlook installed in it.

For recovering deleted emails in Outlook 2016. Go through the steps mentioned below:

Go to Email Folder list >> Delete Items Folder
Deleted items are previewed on right pane
Highlight messages to be restored in a specific folder & Right Click on it
Click Move>> Select Other Folder from the previewed list on the system
List of folders is displayed in Move the selected items to folder selection >> select folder>> Click Ok

All the desired messages are restored to Inbox folder. As there is less chance of data safety and more problem is that it is not necessary that the data is recovered and the file does not become inaccessible. In this way, the best method is the usage of any expert solution for restoring deleted data from Outlook Mailboxes. 

Tip: The above-mentioned method is applicable only for Outlook 2016 and varies with other Outlook editions.

Mentioned below are few steps through which the deleted emails can be recovered in Outlook 2007.Select folder from where you need to restore the deleted items

1. Choose Tools >> Recover Deleted Items
2. A pop-up is displayed showing recently deleted items from selected folders
3. Select email messages to be restored & Select Recover Selected Items Option
4. Select multiple Mail messages and hold Ctrl Key on restored items

Tip: In case the folder comprising of mails is unknown, then in that case, you need to repeat the procedure for every mailbox.

Outlook recovers deleted mail items from the deleted item folder after closing the program. To stop and prevent the automatic deletion from Deleted Items Folder, Follow the steps mentioned below:

1. Click File Tab>> Options>> Advanced
2. In Outlook start and Exit section, uncheck the empty deleted item folder while closing Outlook
3. Click on Ok and save the changes made in recent folder
4. Recover deleted Items Through Scanost.exe while Present in Exchange Environment

There is no way through which the hard deleted data can be restored. So, making a prejudice that scanost.exe will restore deleted mailbox in Outlook is completely useless. But, if MS Outlook is configured with Exchange Server, the probability is that we can get back the permanently deleted data via Dumpster feature if the files are in retention period. By retention period we mean the time period in which the files are kept before deleting them permanently. But there are many policies through which the data can be retained for more than 15 days. Till this time, the files can be recovered till this time and afterward the files are permanently deleted. This property also helps users to restore corrupted Outlook emails. 

Drawbacks of Manual Way of Restoring Mailboxes in Outlook
Though, both the inbuilt utilities are strong enough to recover deleted mailboxes in Microsoft Outlook. But, it is quite difficult to restore mailbox if deleted permanently. This creates problems for the users as they cannot completely rely on the built-in utilities for restoring Outlook Mailboxes. In such cases, a third party utility is the best possible way to recover the mailboxes. So, by our opinion, OST Repair is the best-suited approach to restore the deleted mailboxes. The tool has many incredible features that it can even recover the corrupted OST files. In addition to it, the tool has a brilliant interface that makes it compatible with all Outlook editions be it newer or the earlier ones. 

The Way Forward
To retrieve Outlook Mailbox data items, the users can try the manual approach for resolving entire issue. But, sometimes going manual does not resolve the problems. So, in such cases, the best way out is an automated solution for resolving the problems. So, the users should try Outlook OST to PST Software if they want to restore their data items. The users can completely rely on the tool in terms of recovery. The tool has a credibility to resolve all the issues and does not let a single bit of loss in information.

The simple thing is that all the items can be recovered from the deleted item folder; it implies that still some space is consumed by OST files. The very basic fact about the OST file is that the space consumed by them is unavailable for the other uses. It makes the OST files bigger and just bigger over times and even if you delete few of the items or keep the same record in MS Outlook.

Why We Need To Convert OST Files To Outlook PST?

Most of the users of MS Outlook are quite aware of two types of file formats i.e. OST and PST files. PST files (Personal Storage Table) are the main storehouse of all the data stored in Outlook whereas OST files (Offline Storage Table) contains the replica of data stored in Exchange server. OST comes into existence when the cached mode is enabled from Outlook allowing user to work offline without Mail server. Any changes made will get itself synchronized when connected with the Exchange Server. The blog will be discussing the reasons why we need to convert OST files to Outlook PST file.

Need of Conversion from OST File to PST

The main reason why users prefer to convert their Exchange OST mailbox to PST file is the several issues of OST file that makes the OST file inaccessible or corrupted. Some of the causes that lead to the conversion of OST to PST file are as follows:
  • Issue of Exceeding OST Size Limit
    Size limit of OST file varies with different Outlook versions. In Outlook 2007, size limit supported was 20 GB, which was increased to 50 GB in 2010/2013 versions. Usually, the maximum default size limit is set to 20 GB, which is why performance of Outlook slows down when it reaches or exceeds this size limit.
  • Orphaned State of OST file
    Each OST file is bound to particular Exchange Mailbox and any modification made is continuously synchronized to Exchange Server. When the Exchange Mailbox is dismounted/deleted from the server, the OST file will become inaccessible leading to orphaned state.
  • Synchronization Problems
    It arises if there is any interruption while the OST file is being synchronized with the Exchange Server. Since the OST file is encrypted, decryption key of the Outlook profile needs to be matched with the one in Exchange Server. If it does not, OST file will face synchronization problem making file inaccessible.
  • OST Bound to MAPI Profile
