Events Timing Out During Set-up
In regards to having recurring events perform operations in the background, not sure if that is something they can do but its definitely something you can request at uservoice. If you have a minute, can you please post this request in our Feature Ideas Forum? This is what we use to gauge user interest in new features and help guide future development efforts.
Also be sure to check out our performance consideration page to see if there is something else that can be done to speed up the customer’s site.
