Hello all,
Just a quick question about Exchange Online limits: is there any limit in regards of how many times a EXO inbox can be configured in Outlook client? I have a customer that is having problems when an EXO inbox is configured in Outlook client more than 20 - 25 times? Does any of the Exchange Experts in the house know if this is a know limit? cc @Vasil Michev @Tony Redmond

"When an EXO mailbox is configured in Outlook..." What precisely do you mean when a mailbox is configured? I am unaware of any situations where a configuration change (like changing a mailbox property) would count against some limit. But do tell us exactly what this person is doing so that we can all ponder the great unknown...

SolutionSo it's a shared mailbox... and yes, once you start to ramp up the number of concurrent accesses to a shared mailbox, you start to encounter performance and other difficulties. Why would they use a shared mailbox for this purpose instead of an Office 365 Group, which will have its own synchronization (to the GST, not OST), and so avoid the issue?
