Exporting Mailbox Data
You can export backed-up data from a specific mailbox to a PST file.
To export data to PST (Personal Storage Table) files, you must have a 64-bit version of Microsoft Outlook 2016, Microsoft Outlook 2013 or Microsoft Outlook 2010 installed on a computer running restore sessions.
The request header must contain an authorization token of the current session.
The following parameters must be specified in the URL of the request:
Specifies the identification number of the restore session. For more information on how to get this parameter, see Getting Restore Sessions.
Specifies the identification number of the mailbox. For more information on how to get this parameter, see Getting Mailboxes.
To export backed-up data from the organization mailbox to a PST file, the request body must contain the following properties:
Specifies the keyword to query backed-up mailbox data.
Defines whether to set the size limit for the exported PST file.
If set to true, indicates that you must specify the pstSizeLimitBytes parameter.
Specifies the limit of the exported PST file in Bytes.
You can choose the limit range from 1 GB to 49 GB.
The request command will look for a specified keyword in data inside the organization mailbox. The backed-up data with the specified keyword then will be exported to a PST file and placed to a temporary folder on the Veeam Backup for Microsoft 365 server. After that, the PST file will be transferred as application/octet-stream media to the client. To download, read, convert to PST or perform other actions with the octet-stream, use features of programming languages.
If the size of the exported data exceeds the limit specified for the PST file, Veeam Backup for Microsoft 365 splits the PST file into separate files and exports these files to an archive file of the ZIP format. For example, you specified 1 GB as the PST file size limit. The size of the exported data is 1.5 GB. In this case, Veeam Backup for Microsoft 365 will export data to a ZIP archive. The archive will contain two PST files: one PST file of the 1 GB size and another PST file of the 0.5 GB size.
You can use Swagger UI to download the octet-stream file by clicking the Download action link, which server returns in the response body after a successfully completed export operation. For more information, see Evaluation in Swagger UI.
The server returns the following response to the client.
