I am getting "Waiting for Microsoft Azure to send the response back, An internal server error occurred. Try again later" in Quest On Demand tool while trying to migrate an Archive mailbox for one user from Source tenant to Target tenant

Hi,

We purchased Quest One Demand license for M365 tenant to tenant migration and I am using Quest On Demand tool for migrating few Source M365 tenants to a Target M365 tenant. And currently I am migrating a user's Archive mailbox which is around 462GB and I created a task for this Archive mailbox migration.

However, if I look at the events for this task, I see that, the task got stuck with the message  "Waiting for Microsoft Azure to send the response back, An internal server error occurred. Try again later" .

And the task got stuck with this message for the last 10hrs. I checked one article and found that if there is throttling on the Source M365 tenant and I increased it for 30days.

But I still see that the task got stuck with this message.

Is there anything I need to look at? How this issue can be resolved? The already took more than 36hrs and still got stuck with this error message.
