3.  Getting started with EdbMails

One of the reasons we fell in love with EdbMails is that the majority of the company’s products have a user experience that is blissfully simple without sacrificing any of the features, which you don’t find in many other IT products.

However, you may need help getting started, or you may simply want to gain a good understanding of the process before using EdbMails OST to PST Converter. In light of this, let’s take a look at the basic OST to PST conversion procedure and some of its features.

a.    Software Download and Installation

Of course, the first step is to download and install the software. The installation is quite simple and straightforward and we rarely noticed any hitches. EdbMails can be installed on all PC’s running Windows Operating System with MS Outlook installed. We tested it on both 32 as well as 64 bit Windows OS without experiencing any issues.

b.    OST file recovery with EdbMails

Microsoft Outlook email client is used by millions of businesses around the world. Unfortunately, there is no way to manually recover from this situation if your OST becomes inaccessible or corrupted. EdbMails Exchange OST recovery tool is a fantastic choice for recovering a corrupt/inaccessible OST file and deleted OST items, as it can both solve the OST corruption problem and quickly restore the deleted items too. Another excellent feature is that it is compatible with all versions of Outlook (2000-2019). As a result, you shouldn’t notice any file compatibility issues. We tried exporting an OST file to PST and we could open the target PST on many Outlook versions such as 2019, 2013, 2016, 2010, and 2007 without any issues.

c.     OST to PST file conversion with EdbMails

When an Exchange Server fails, EdbMails OST to PST Converter Software restores OST file mailboxes and converts them to Outlook PST files. According to EdbMails’ product benchmark analysis, the software converts OST file emails faster than most other competing tools. It opens OST files in minutes and takes about a week to extract a 1TB file which is pretty decent. Furthermore, EdbMails OST converter tool consistently extracts mailboxes from an OST file while avoiding data loss. We extracted a small number of mailboxes and found that the message contents and encoding were perfectly preserved.

d.    Import OST to Office 365 with EdbMails

If you are looking for a cost-effective and easy way to import OST files into Office 365 accounts, EdbMails OST Recovery and Migration tool is the way to go. Many Microsoft MVPs highly recommend this tool, which is designed to import OST to Office 365 for both individuals and enterprises all over the world. EdbMails provides the most useful features such as incremental migration, auto mailbox mapping, Oauth 2.0 secure modern authentication, impersonation rights setting and so on. We put the OST import functionality into Office 365 to the test. If you choose the modern login method, the tool will take you to the Office 365 login page which according to our opinion is pretty secure. It is also possible to migrate public folders and shared mailboxes from the tool’s interface. If the names of the mailboxes are similar, EdbMails provides the option to automatically map the mailboxes, which saves time.

e.    Converting mailboxes from different languages

Organizations and users from all around the world usually use mailboxes on global domains. As a result, the language settings in the matching OST file stored locally are synchronized. EdbMails supports non-English, ANSI, Unicode, and special characters during OST to PST conversion including Arabic, Hebrew, Russian, German, Chinese, Czech, Korean, and Japanese characters. We put it to the test with a Chinese-character mailbox, and it did a good job of preserving the entire encoding, earning us a plus point.

f.      Filter options to convert specific mails

When converting an OST file to a PST file, EdbMails filter options are extremely useful because they allow you to weed out unnecessary messages while exporting mail data that is of interest. It prevents the conversion of all emails and folders. You can apply filters to mail items to ensure that only the necessary data is exported during the conversion. Simply set the condition to include/exclude items from the export operation based on the date, Subject, From, To, Cc, Bcc, attachments name, and other criteria. We used the Date filter option to export mail content between specific dates and absolutely loved this feature.

g.    PST file split option to split oversized files

When the Offline Outlook data file (.ost) is large, it can cause a number of issues . The best way to reduce the size of an OST file is to split it into small chunks of PSTs. There is, however, no Microsoft built-in tool for dividing an Outlook data file. During the OST to PST conversion, EdbMails allows you to simply split the original OST file into PST files. The PST file size can be customized from the tool’s interface and later merged using EdbMails’s free PST merge feature. This earns another point from us because of how well they’ve combined the two options in a single tool. That is very impressive.

h.    Security and Privacy

EdbMails prioritizes security and privacy. It uses secure Microsoft APIs for migration and follows Microsoft rules. EdbMails offers a safe OAuth 2.0 modern authentication login method based on ADAL for Office 365 conversion (Active Directory Authentication Library). EdbMails is also ISO 27001:2013 compliant and certified software, ensuring a secure export and migration process. Your credentials are never saved on EdbMails’ GDPR-compliant servers.
