Hello @brichardi
Thank you for your inquiry. There is a manual method for moving the OST to another computer that involves first converting it to PST. However, this may take some time. In such a case, I would recommend an automated solution I discovered on this Linkedin blog. Both methods are listed below.
Step 1: Using Outlook's Import/Export wizard
- From the Outlook's interface, click on File on the top left corner and click on Open and Export
- Choose the Import/Export option which opens the Import and Export Wizard
- Select Export to a file and in the next screen select Outlook Data File (.pst)
- Verify and check mark the Include Subfolders box.
- Browse for the location of where you would like to Save the file and it will be completed. Method 2. Follow the AutoArchive method of saving emails from Outlook
The next method is the AutoArchiving which saves a copy of your mailbox items at regular intervals as .pst. Follow these steps to enable the Auto Archiving feature from Outlook.
- Click on File in the top right corner of MS Outlook > Options and then Advanced in the left menu.
- Under AutoArchive click on the button AutoArchive Settings.
- Checkmark the box Run AutoArchive every and specify how often to run the AutoArchive.
- Fill in the other details such as location to save the PST Archive and click OK.
These steps are detailed on the Microsoft support pages.

Method 3. Automatic Solution of moving the OST and users to a new location
The previous two methods work if your mailboxes are small in number or if you don't run into any problems with Outlook. However, if you have large sized mailboxes with a lot of attachments or mail items, then you need to go with an automatic third-party OST to PST converter solution to ease the entire process. This method will convert the .ost files from Outlook to .pst format. Using this PST file, you can import all the users into your new Outlook profile.
