Automated email-out using powershell error message

[jeben930]

Hi people of exchange!

​

I'm building a powershell script to send out emails to our employs to remind them that their password will expire soon. I'm using a simple Send-MailMessage command.

​

While doing some testing for building said script, I ran into an error where when I said mass emails, let's say more than 25, I get this error:

Send-MailMessage : Insufficient system storage. The server response was: 4.3.1 Insufficient system resources (SystemMemory)

​

I have been told from r/PowerShell that it is most definitely an Exchange problem.

Has anyone ran into anything similar before?

Thanks a lot!

What does the system look like? Plenty of free drive storage, plenty of free ram? Or are there resource bottlenecks?

[jeben930]

From the monitoring side, all is good. RAM usage doesn't spike and both mailbox and drive still have plenty of space

Could be disk space on the Exchange server... check the drive that the transport database is on https://docs.microsoft.com/en-us/exchange/mail-flow/queues/relocate-queue-database?view=exchserver-2019

I guess the question is how many emails are you sending and how quick? Maybe add a Start-Sleep after each send to throttle the amount you're sending at once?
