You backed up a private channel in Microsoft Teams. Later, you deleted the channel and want to restore it from the backup.

A backup agent error: 'Channel Channel id=<id> was not restored

You run a backup of Microsoft Office 365 mailbox and/or OneDrive with Acronis True Image 2019/2020

This article applies to:
Backup, recovery, or other operations with Microsoft 365 items fail with the following error:
.NET exception 'System.Net.WebException' has occurred: The underlying connection was closed: An unexpected error occurred on a send
This applies both to C2C backup and to local Agent for Microsoft 365.
You log in the Protection Console as a customer group company administrator and attempt to add a Microsoft 365 organization as described in the User Guide.
This leads to a download prompt for the local agent for Microsoft 365 instead of redirecting to the Microsoft 365 login page.
The behavior is expected if the tenant has "Enhanced security" enabled.
Introduction
Starting from Acronis True Image 2019 Update 2 (Build 14610) you can back up OneDrive and mailboxes for Microsoft 365 Consumer accounts. Backups are saved to Acronis Cloud. You need Acronis True Image Advanced or Premium subscription to use this feature.
Restoring large Microsoft 365 items might take significant time due to throttling on Microsoft side. In such cases, we recommend temporarily disabling Exchange Web Services API throttling to improve the performance during restore of Microsoft 365 items.
