Restoring mailbox from Offline Exchange DB, job stops after 24 hours and getting throttled

Hello @TomerA 

This is FR24 and Exch 2019 so its leveraging EWS for the recovery. I think you can remove that key as its not needed here.

You should leverage the following for throttling policy. NOTE: This is different than the MAPI throttling setup as it is leveraging EWS!

https://documentation.commvault.com/11.24/expert/112073_configuring_service_account_to_manage_exchange_2019_messages_using_exchange_web_services.html

If that does not resolve the issue, can you try a adding a couple more accounts and see if you get similar throttling errors? Side not just curious have you attempted a restore to PST if you have Outlook X64 2003 installed?

I've actually tried that article first,  i`v pretty much at this point set most settings in policy to ‘unlimited’ ,didn't change anything

as for PST , it works fast , but i was specifically asked by client to use the functionality of restoring directly to mailbox

@TomerA Have you attempted to add additional service accounts?

What type of messages are you seeing in the logs referencing throttling? What happens if you recover a smaller folder for that same mailbox I assume it completes without issue?

This and alot of it , it would work for a few minutes and throttle another 5 , for hours

if this job was smaller I'm guessing i wouldn't have noticed issues since it would just take alot of time , but since its a really big mailbox each time i run this it progress 50-100k items and skip 600-700k items from earlier run , each time it gets closer to 24hour crash before it finishes skipping existing items.

Thanks @TomerA 

There was an update that addressed some throttling for the proxy machines you mentioned 11.24.21 is that installed on the machine where you are performing the live browse? 

Thanks

Hi Scott,

Hi tried again this weekend after updated all the enviroment to 11.24.25 , still same results 

Throttling and job ends after 24 hours exactly.

Hi @TomerA , hope all is well.  Can you open a case for this issue and share the number with me?

Apologies for the delay, just got back from holiday 

Hi Mike,
