Hi @AprilCarr1 ,
It appears that your company is carrying out some system upgrades outside of Concur and the change requires users NOT to submit expense reports. It seems that you have wait for a mail from Zach Clayton confirming that the system can be used again. Until then, you just need to wait. Hope this helps.
@AprilCarr1 just to add on to Rohan's comment, normally when a company needs to make changes they will create an audit rule to have user's not access the system. That is what has been done here. Once they are completed with changes, they will deactivate the audit rule and you will be able to submit. You can also reach out to your site admin to get more info if you need!
