Name: Set up Recurring OOF Replies in Outlook
|
||
Description: This script helps to automate recurring out-of-office replies for Microsoft 365 users
|
||
Version: 1.0
|
||
Website: m365scripts.com
|
||
|
||
Script Highlights:
|
||
~~~~~~~~~~~~~~~~~
|
||
1. The script can be executed using either username/password or certificate-based authentication (CBA).
|
||
2. It automatically calculates and sets the out-of-office start and end times for the upcoming occurrences based on the provided day and time parameters.
|
||
3. This script is primarily designed for setting up recurring out-of-office replies with the help of scheduling tools like Windows Task Scheduler or Azure Automation.
|
||
4. This script allows admins to set up recurring out-of-office replies for themselves or their users, and it also enables users to configure their own recurring OOF replies.
|
||
5. The external out-of-office message defaults to the internal message if not provided.
|
||
6. The external audience defaults to "All" if not specified.
