Hi,
We have a requirement where we want to use a generic account for Teams live events/webinar scheduling. Since that account has to have a Exchange Online mailbox enabled, we do not want any type of emailing activities on the mailbox. Account should only be allowed to schedule live events/webinars/meetings. It should not be able to send/receive other emails with attachments. I know if i restrict it from size limitation, it won't be able to send/create meeting invites. Is there any other way to achieve the same?

Hi @GoodResource ，
Do above 2 transport rules work for you? If you have any questions or needed further help on this issue, please feel free to post back. If the issue has been resolved, please mark the helpful replies as answers, this will make answer searching in the forum easier and be beneficial to other community members as well.
I suppose you can create a mail flow rule that restricts messages based on the message type (The message properties > include the message type > calendaring).
@Vasil Michev , Seems for Webinar, one needs to have send email capability even if we block sending email except Calendaring. Live events work, but Webinar doesn't work.
Hi @GoodResource ，
According to your description, you only want to restrict the user from sending and receiving mails with attachments. Please correct me if I misunderstand your question.
If I understand your question correctly, you seem can create 2 transport rules to meet your request, below rules I have created in my lab for your reference:
Note: attachment's file extension you could add whatever you want.
Enable these 2 rules at the same time, you will restrict the specific user from sending/ receiving mails with attachments.
