Hello @Janet Leroux,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues that this may have caused you. Those emails are received by users who are added as administrators on shared folders. To prevent them from receiving those emails, you can remove the admin permission from the shared folders (Not selecting any of the permissions will still allow them to modify the folder information but will not be able to add users on it). For business accounts, there is a policy "Prevent user status emails to shared folder admins" which would stop those emails without removing the admin permissions.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
We currently have a Teams account - I think the solution is to upgrade to a business account. Is this correct?
Thank you so much for your help! I was able to update the users by removing the admin permission.
