Office Repair due to email integration repeatedly breaking

SUGGESTED

We are having to do a Microsoft Office repair 2-3 times a month for our Sage 300 clients that use Outlook email integration (not SMTP) to send invoices. The problem appears to happen after automatic Office updates according to our IT department. Clients have various flavors of Office including 365 and Pro Plus. Sage 300 version are 2019 to 2022. Any ideas?
