Can I back up my mailbox without Exchange administrator’s involvement?

The OST to PST Converter is designed keeping the end users in mind. You can back up your mailbox to PST file on your end without any involvement of Exchange administrators.

I am using Thunderbird on my personal system as it is free. Can I export my official emails from my Exchange account to Thunderbird using this tool? I don’t want to disturb my Exchange administrators for this simple task.

You can export your official emails from OST files to MBOX format using this tool. You can perform it yourself without any help from Exchange administrators (however, make sure that your company policy allows you to do this).

OST files are on client systems. But why this tool has options to save OST files to Exchange Server, Office 365, etc.?

Exchange administrators can use this tool after Exchange disasters to restore user mailboxes to a live Exchange Server or Office 365. Only thing is that they have to collect OST files from the client machines.

I was very stressed when the error message saying "Encounter a large number of conflict items with OST file" popped up. But this tool helped in relieving all my stress in a jiffy. I regained access to my files. The good aspect about the tool is that I was able to save my recovered files into multiple formats.

I am using this software for quite a time now. The software has made it easy to repair the corrupt and inaccessible OST files. I am not only able to recover my files, but can also export them into PST format within a very short time interval.

Synchronization between the Exchange Server and OST files often results in error. I have faced off this sort of error number of times. But, all thanks to OST to PST recovery software, it can fix OST error causing corruption. It can also recover all the lost and deleted OST data into PST file format.

OST corruption tuned out a horrific scenario when I got to know the fact that it needed conversion from OST to PST. Unlike many others, I too considered it as tough job as it required high technical platform and corresponding provisions. However, OST to PST software made it all easy by recovering and safely converting every single data from OST to PST without generating errors and losing data.

When you go to search for a solution of a critical problem and come out with the best solution, then it is the best feeling ever. I went through the same situation last week. Viruses had attacked the respective OST files of MS Outlook on my system and left me unable to access the OST data. For the moment, I went online and searched for a solution, thereby coming out with OST to PST software. It glanced over the problem and fixed it immediately. Finally, I could access the data of OST file.
