If you are synchronising your Office 365 account with your on-premises exchange/Active Directory, you will know that you cannot edit exchange user properties using the Office 365 administrator portal.
If you try, you will come across this error or a similar one:
The operation on mailbox “X” failed because it’s out of the current user’s write scope. The action ‘Set-Mailbox’, ‘EmailAddresses’, can’t be performed on the object ‘X’ because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.
If you use Exchange 2003 (I’m not sure if the same applies to later versions), you may have noticed that you cannot set a user’s mailbox size to anything greater than 2097151KB (2GB).
The good news is that this limit is only GUI imposed and not a hard value fixed on the exchange server software it self – I myself am not sure of the reasoning behind this artificially imposed limit.
Increasing a user’s mailbox is really easy and safe – however, I don’t recommend that you configure the size to some unreasonable or extreme limit. Between 2 and 5GB sounds just about right.
As always, a full backup of the mail store is recommended before changing any settings on the Exchange.
