Hi,
I have just upgraded form 11.28 to 11.36.46
After the upgrade I get the error’s below on my O365 mailbox backups.
I backup to on-prem. I have upgraded my Index server & MA’s as part of the upgrade.
Any help would be great.

Hi
Good day!
The error you're encountering is 'Throttling from Exchange. Failed to process mailbox due to [Value cannot be null. Parameter name: key]', is likely related to throttling issues that are common in Exchange Online backups.
Please verify the configuration
Streams per access node: 10; if we have 2 Access nodes, set it to 20 Streams
Azure Apps: 5
Please try running the failing Mailbox separately and see how it goes
Please work with Office365 Admin to relax the throttling on the Tenant Level. refer the below kb articlehttps://kb.commvault.com/article/68619
If the issue persists, consider reaching out to Commvault support for further assistance

low & behold the next evenings O365 backup’s ran 100% ……….. no changes needed.
