Veeam – Backup your Office 365 mailboxes (on a UNC path)

Today i’d like to provide you another one of my straight-forward walk through guides. Everybody is talking about cloud. Is it either a private cloud or a public cloud, or probably something between (a hybrid cloud, you don’t say…). So many people and companies want to have their stuff migrated to the cloud or are already using cloud technologies.

Microsoft Office 365 is also one of these cloud technologies. It’s your mail hosted in the cloud. It is available in different sizes and versions, combined with powerful office and collaboration applications (Word, Excel, Outlook, Skype for Business and Sharepoint Online and so on) or just the mail part of it. You can choose whatever you need, and at very attractive pricing conditions.

But today we don’t talk about how cool and great this Office 365 stuff is. We wanna talk about how you backup your mails. Your mails are stored somewhere in the cloud (actually a physical datacenter located somewhere). I don’t know if Microsoft does backups for YOUR mails. It’s always better to do that by yourself. Then you know it’s working and you can recover in case of a user deleted something, or whatever can happen with these mails.

So let’s talk about Veeam Backup for Office 365.

This nice piece of software from Veeam is now available since a few days. It’s working very fine, and it is simple to install as you know that from other Veeam software. As mentioned above, this post should guide you through the simple setup and configuration of Veeam Backup for Office 365. When i don’t count the time it took to take screenshots, then the installation is done in a few minutes. Promise. Let’s dig into that.

  7. Schedule your backup. Click “Finish” to close the assistant.


But wait… Where did I configure the backup repository as i know it from Veeam Backup & Replication? Yes, you don’t do that when creating a backup job. Let me show you that in the next step.

Step 4 – Change repository

As per default Veeam Backup for Office 365 creates a default repository on your local hard disk (default: C:\VeeamRepository). That’s nice when you like to keep it simple and all togehter on one place. You can use that if it’s for example on a virtual server with a lot of space. This server should be backed up separately.

But if you like to change the repository to another storage device, like a NAS or so, then you have to change the path and point it to a UNC path.

  1. Click the Menu button in the top left corner and choose “Options”.


  2. To change the repository path, if you like to, just browse for a directory or add a UNC path to your backup device.

    Change repository path

  3. It looks as Veeam Backup for Office 365 doesn’t like my network attached storage device. Let’s troubleshoot that quickly.

    Error selecting UNC path

  4. Open Windows services manager and stop the “Veeam Backup for Microsoft Office 365 Service”.

    Windows services management

  5. On your server, create a local user account with administrative permissions.

  6. If you’re using a Synology NAS device, or probably a FreeNAS server, create there a user account too, with the same username and password!.

    Hint: Make sure that this useraccount has read / write access to the shared folder on your storage device where you’d like to point the repository path to.

  7. Back on your server, edit the “Login” credentials of the Veeam Office 365 service. Change it to the newly created local user account.

    Change service account

  8. After changing the login credentials of this service, start the service and open the Veeam Backup for Office 365 console.

  9. Open again the options dialog box.

  10. Now enter the UNC path to your network attached storage device.

    Change repository

Now Veeam Backup for Office 365 should be all fine and accepting your UNC path.
