As teams is based on SharePoint, are we able to use OPM to connect to a teams site. It would copy/move emails/attachments to the teams document library but then also have to trigger whatever teams does to inform team members that a new file has been uploaded.
Yes you can connect a team site to OnePlace Solutions (Mail & Docs), to save emails/ attachments to. To trigger the alert, Flow could achieve this or possibly SharePoint Webhooks.
Hope this helps, please let me know if you'd like further information
