While running a demo for a customer i was trying to add a new Org into my VBO server
We come across this error message around config Exchange Web Services (EWS), I’ve personal not seen this message before when adding an new ORG.
However this the 1st time I’ve tried adding an org into version VBO 8.3, for context i’m using Modern authentication.

Try this: https://www.veeam.com/kb4820
PS line:
Install-Module ExchangeOnlineManagement -Scope CurrentUser
Import-Module ExchangeOnlineManagement
Connect-ExchangeOnline -UserPrincipalName admin@yourcompany.pl
Get-OrganizationConfig | Select-Object EwsEnabled
When show this:
EwsEnabled
----------
False
You must try this:
Set-OrganizationConfig -EwsEnabled $true
Now this command:
Get-OrganizationConfig | Select-Object EwsEnabled
and you must see this:
EwsEnabled
----------
True
retested
+2This is a known issue at the moment, but there is a fix available.
Basically you need to have EWS enabled on the m356 tenant as well as mailbox.
Check with PowerShell:
Get-CASMailbox User1| fl EWSEnabled
Get-OrganizationConfig | fl EWSEnabled
Both must be either “emtpy” or “true”

+22Thanks for sharing the solution
+4also, FYI, Exchange Web Services (EWS) is being deprecated October 1
Microsoft is retiring Exchange Web Services (EWS) for Exchange Online as part of a phased shutdown plan driven by security, scalability, and reliability concerns. EWS, introduced nearly 20 years ago, will be disabled by default on October 1, 2026 and fully shut down on April 1, 2027 for all Microsoft 365 and Exchange Online tenants. On-premises Exchange Server deployments will remain unaffected.
