HI How to configure custom email content for mailbox quota warning.
https://learn.microsoft.com/en-us/powershell/module/exchange/set-systemmessage?view=exchange-ps
Example:
Set-SystemMessage En\WarningMailbox -Text "Your mailbox has exceeded the warning limit specified by your email administrator. Please reduce the size of your mailbox."
Hello Andy David, it seems that my use of new system message is not working. Do I need to delete the new system message and use set system message?
Looking forward to hearing from you！
Hi Andy david, do I have to use the set-systemmessage command? Is it feasible for me to use new-systemmessage? I found that when I use new-systemmessage, when the mailbox quota reaches 90%, it does not alarm..
That should work, What is the exact command you are using?
HI Andy david,
It's been resolved, thank you for your support.
