0. About the Out of Office Admin roles
Out of Office Assistant for Jira Cloud relies on Jira admin roles to decide who can do what:
End users can create and manage their own out of office rules. They can also see anybody else's rules.
Project admins can, in addition, create and manage rules on behalf of any users, with the scope of a single project. See the Project Admin Walkthrough for more details.
Jira admins can create and manage rules on behalf of any users, across any projects and issue filters. Additionally, they can
change the app global settings
administrate REST API tokens
setup the integration with Tempo Planner (now called Capacity Planner)
Rights and limitations of Out of Office admins
Besides that, it's possible to appoint Out of Office admins.
Admin rights: Out of Office admins can create and manage rules on behalf of any users
Limitations: Out of Office admins cannot change the app global settings, administrate REST API tokens, or setup the integration with Tempo Planner (now called Capacity Planner)
Giving Out of Office admin rights to power users
Sometimes you may want to have Out of Office administrated by a team lead or other type of power user, without making them Jira admins or even Project Admins.
You will need a Jira Admin to grant these rights.
Go to Out of Office > User Administration > Global Settings
Once in the Global Settings, access the Permissions tab
Here, you can add any number of single users; alternatively, it's also possible to add a group, and make every user in that group an Out of Office Admin.

1. Launch the Out-Of-Office User Administration
From the main menu select Jira Settings / Apps. Then click on User Administration in the Out-Of-Office Assistant section

2. Filter users
The User Administration view allows you to filter:
By username
By project
By status (out of office users, in office users, users with active rules, users with no active rules, etc.)
In the Actions column, you can:
add rules on behalf of users (
). The forms you will see are the same as for the user.
if there are already rules defined, you can click on the eye icon to see the existing rules and manage them. This will open a new page with the list of rules for that user.

3. Reassignments Analytics
When an issue of a user is reassigned by the Out-Of-Office Assistant, you get a message in the Reassignments column

If you click on it, you see which issue, when and to whom it was reassigned.
It will also show errors when reassigns didn't work, e g. if the assignee is also out of office and has no coverer.

4. Add out of office tags to mentions:

Every user can choose if and how such a tag will be added, when he or she is mentioned. As admin you can choose the default that is used for new rules.

You have three options:
Don't add an ooo tag to mentions in comments
Add an ooo tag to mentions when out of office
Add it already days before out of office
And some options for before the time tag:
5. Enabling the Rest API
5.1 Rest API documentation
The complete description of the Rest API for the Out of Office Assistant you find on the Swagger website: Out of Office Assistant Rest API | resolution-cloud | SwaggerHub.
5.2 Authorization by User
Out of Office Assistant Rest API Tokens
Rest API Tokens made for the Out of Office Assistant only affect reading, creating, updating and deleting OoO rules. They can't be used for anything else in your Jira Cloud instance.
There are two options how to handle Rest API tokens. Either you can ...
A) Enable all users for creating their own Rest API tokens, by checking "Allow users to create there own Rest API tokens", the users will only be able to create tokens for their own rules, or

B) ... by creating them for them:
5.3 Authorization by Admin
To create tokens you can go to the Out-Of-Office User Administration tab "Rest API Tokens". There you find a list with all created tokens.

Hit "Create New Token" button. Select a user and a scope.

A token is always issued for one specific user. As scopes you can choose between "READ / WRITE & DELETE" and "ADMIN". "READ / WRITE & DELETE" enables read, write and delete actions the rules of one specific user. "ADMIN" allows to do the same, but for all users of the instance.
Hit "Create Token".

Now you can either copy the token and send it to the user in some secure way, or send the user a link where he can obtain his token.
I he follows the link he gets to his out of office rule list, with a button get the token.
