Chad,

Just to be sure I understand it correctly. You are using an MFA account for Exchange, and want to use a "legacy" account for SharePoint?

I thought our O365 world was set for MFA -- both for Exchange and SharePoint. Once turned on, shouldn't it apply to all O365 applications? Or does SharePoint have a separate location for MFA?

Chad,

To solve your issue with the failed LegacyAuthProtocolsEnabled check, you indeed need to follow Niels's advice and set -LegacyAuthProtocolsEnabled parameter to $True.

It's not about the MFA enabled to only the selected part of your organization, but because of the following specifics: "Setting this parameter to $False prevents Office clients using non-modern authentication protocols from accessing SharePoint Online resources."

Thanks Polina. Do you know if by changing this parameter within SharePoint, it will affect our current user base and their connectivity to SharePoint? Or is this isolated to just our VEEAM backups? I appreciate all the feedback. Thank you!

Chad,

It will take effect for the entire SharePoint Online, however, only in terms of enabling ability to access SharePoint Online resources for third-party applications that cannot use modern authentication.

When I try to explorer the test backup we've made we receive the error below:

incompatible veeam backup for microsoft office 365 server version. Server version must be newer than 9.6.3.804

Please advise.

Regards,
Kevin

Kevin, did you install the explorers which come with the beta download? And is VBO installed on a separate server?

We bmp into this error when backing up one users OneDrive. It's in English up unto the error Message from Office365, wich is in Norwegian.
13.03.2019 23.46.55 :: Failed to process OneDrive: Rune Xxxx (https://kxxxxx-my.sharepoint.com/person ... _xxxxxx_no). Forsøkt operasjon er ikke tillatt fordi den overskrider terskelen for listevisning som er aktivert av systemansvarlig. :: 0:00:05

It seems to relate to a limit of 5000 items returned in a List View.

From the article below.
"There are many ways you can work with or query a SharePoint list or library without receiving a List View Threshold warning. Using the following ideas, you can get the information you need and stay within the 5000 item List View Threshold. For more info on the List View Threshold itself, see Overview of lists and libraries with many items."

Did I miss something in this thread regarding MFA? I'm trying to test it but running up against the legacy auth error. I saw that LegacyAuth needs to be enabled for Sharepoint, but I thought one of the selling points of this version 3 was MFA support. Legacy auth is still needed? I was hoping to not have to enable that with V3.

Danny, correct. MFA is used for Exchange but for SharePoint we still require LegacyAuth for now. You can resolve this via PowerShell as explained in this post.

Hi,

Will v3 offer the possibility to migrate Onedrive backup to another tenant ?
Currently we can migrate data only between users of a same tenant even if we have multiple tenant set in Veeam 365

This is working for Exchange in v2

Thank you

Hi Alex,

Enabling cross-tenant migration is on our roadmap, but it will not be available in version 3.0.

Thanks

I've a customer asking if we have added the feature in 3.0 to backup the O365 Audit logs from O365. I can't find the answer to that - did we add that feature?
