OFFICE 365 MAC DOWNLOAD SIZE UPDATE
Naturally that means you can update any subset of your users by filtering the output of Get-Mailbox first. PS C : \ Scripts > Get - Mailbox - Resultsize Unlimited | Set - Mailbox - MaxReceiveSize 55MB - MaxSendSize 55MB And although we can see the transport configuration (which has unlimited max send/receive limits) we can’t make any changes to those settings. There’s no access to send/receive connectors or AD site links. With Exchange Online we get far less administrative control as the customer than we do for on-premises Exchange. These include:Īs a general rule organizations tend to apply a consistent limit across all of those settings, however the capability is certainly there to customize the configuration to suit nearly any scenario that arises (for example, preventing large email messages from being sent to very large distribution groups). Message Size Limits != Attachment Size LimitsĬomparisons with On-Premises Exchange ServerĪs many of you already know there are multiple places that message size limits can be applied for an on-premises Exchange Server environment.Managing Message Size Limits for Existing Mailboxes.
Using Mailbox Plans to Configure a Default Max Message Size Limit.
Comparisons with On-Premises Exchange Server.With that said, let’s look at how you can configure the message size limit in Exchange Online. The more likely reason in my view is that it is large enough number to completely silence any customer complaints (and therefore remove the burden of those support calls) about the previous limits. I suspect the new 150MB limit is not due to Microsoft endorsing the use of email for sending big files. All of this may actually lead to a poor experience for your users, and an increase in support requests for you.
Consider the impacts this will have on your network bandwidth, client performance, on-premises infrastructure (if you’re running a Hybrid configuration), journalling, and the fact that you’ll more often than not find that other companies you’re emailing support a far smaller message size limit. By all means increase the message size limit to suit your business, but don’t just crank it right up to 150MB for the sake of it. While I am generally of the opinion that email is a poor transport mechanism for large files I can understand how the modern era of fast networks, cheap storage capacity, and the convenience of email all come together to create the situation where large email attachments become a requirement.īefore we go any further let me point out that just because you can set a message size limit of 150MB, it doesn’t mean you necessarily should. The previous limits were a deployment blocker for some customers that I’ve worked with who either had a higher limit for their general user population (often more like 50MB) or who had a few specific mailboxes that needed to receive very large emails (often a system-monitored mailbox). This is quite a large increase from the previous limit of 25MB (actually 35MB, I’ll explain why shortly) and no doubt will be a welcome change for many customers. Microsoft has announced that Office 365 (Exchange Online) now supports up to 150MB email messages.
