Hello!
Is there anything new going on with Microsoft and throttling?
We are on 11.32.23 and we are getting the throttling message on individuals’ mail boxes.
Been seeing
Throttling from Office 365. Failed to process mailbox due to [EWS Error in enumeratings folders. Reason: Too many concurrent connections opened., Cannot open mailbox
on several Exchange Online jobs lately.
We have been following this:
Best Practices for Exchange Online (commvault.com)
We are using 10 streams on all our customers’ Exchange online backup config.
Did Microsoft bandwidth become more restricted?
I will lower one customer to 7 streams now, just to see what happens.
But please let me know if there are any known issues or changes done on MS side.
