-->Message throttling refers to a group of limits that are set on the number of messages and connections that can be processed by an Exchange server. These limits include message processing rates, SMTP connection rates, and SMTP session timeout values. These limits work together to protect an Exchange server from being overwhelmed by accepting and delivering messages. Although a large backlog of messages and connections may be waiting to be processed, the message throttling limits enable the Exchange server to process the messages and connections in an orderly manner.
Note
Back pressure is another feature that helps to avoid overwhelming the system resources of an Exchange server. Key resources, such as available hard disk space and memory utilization are monitored, and when the utilization level exceeds the specified threshold, the server gradually stops accepting new connections and messages. For more information, see Understanding back pressure. There are also static limits that are available on messages, such as the maximum message size, the size of individual attachments, and the number of recipients. For more information about message size limits, see Message size limits in Exchange Server.
You can set the message rate limits and throttling options in the following locations:
Mailbox servers and Edge Transport servers. Collectively, we'll refer to these as transport servers.
Send connectors
Receive connectors

Note
The Pickup directory and the Replay directory that are available on Edge Transport servers and Mailbox servers also have messages rate limits that you can configure. Typically, the Pickup directory and the Replay directory aren't used in everyday mail flow. Microsoft word download for mac. For more information, see Configure the Pickup Directory and the Replay Directory. The maximum number of message files per minute that can be processed by the Pickup directory and the Replay directory is 100. Each directory can independently process message files at this rate.
Message throttling on Send connectors
The following table shows the message throttling options that are available on Send connectors. Send connectors exist in the Transport service on Mailbox servers and on Edge Transport servers. For more information, see Send connectors.

Message throttling on users
Mac Mail Infosys Microsoft Exchange 2017
The Microsoft Exchange Throttling service tracks resource settings for specific uses and caches the information in memory. Mail flow throttling settings are also known as a budget. Restarting the Microsoft Exchange Throttling service resets the mail flow throttling budgets.
Each mailbox has a ThrottlingPolicy setting. The default value for this setting is blank ($null). You can use the ThrottlingPolicy parameter on the Set-Mailbox cmdlet to configure a throttling policy for a mailbox.

I've rolled out O365 to networks with say 10x iMac's before. Have used both Mac Mail and Outlook. Both work OK..not as well as Windows as you'd expect, but well enough. I mainly see issues with O365 accounts on Mac's not syncing when the site has slow internet, especially if that's combined with large-ish mailboxes. The mail client tends to get stuck downloading all the email attachments and just stalls. What is the speed of the internet there?
macOS is fully up to date? Do you have any AV installed, if so have you tried removing it. Any other programs running at logon that could be interfering? Disable any Mac Mail addons. Also, slow spinning hard drives in older iMac's tend to lag out the mail apps, which tends to bring user complaints.
