Users with full access to someone else's mailbox can no longer send emails
Hi,
It used to work great but it stopped working a couple of weeks ago for no apparent reason? Now even when we grant full access to someone's mailbox they can't reply or send any email from that mailbox. They get a message that they don't have permission to do so.

- Full access to a mailbox doesn't let the permission holder to send from that mailbox. Send As or Send on Behalf permission needs to be granted explicitly. In your case that permission could have been revoked, so you have to grant it again.
BMERCIER45 Here's the article that tells you the truth: https://support.microsoft.com/en-us/topic/how-to-grant-exchange-and-outlook-mailbox-permissions-in-office-365-dedicated-bac01b2c-08ff-2eac-e1c8-6dd01cf77287
In particular, this is the paragraph to pay attention to:
Full access permissions let a user directly sign in to a mailbox by using Outlook or Outlook Web Access (OWA) and then add that mailbox as a secondary mailbox in Outlook. However, full access permissions do not let the user send as or send on behalf of the mailbox. Those permissions are granted separately.I'm not completely sure where your screenshot has been taken but the permission description doesn't seem to be correct. Here's what you'd see under mailbox delegation in EAC. You see, sending permissions are separate from Read&Manage.
