How do I bulk add Microsoft 365 mailboxes?

Bulk adding connects many mailboxes at once. Mailbox owners don’t need to do anything. Instead, you sign in once with a Microsoft 365 admin account.

To add just one mailbox, see How do I add a single Microsoft 365 mailbox?

Before you start

You need a Microsoft 365 account that is either:

• A Global Administrator, or
• A user with the Privileged Role Administrator role.

To set up a separate admin account for this, or to limit which mailboxes timetoreply can read, see How do I limit which Microsoft 365 mailboxes timetoreply can access?

Add your mailboxes

1. Click Entities in the bottom-left corner.

2. Go to Mailboxes and click Add mailboxes as admin.

3. On the Microsoft 365 card, choose an option:

   • Bulk Link Mailboxes connects the mailboxes.
   • Bulk Link Mailboxes & Calendar also syncs full-day Out of Office events from Outlook calendars to each person’s leave days in timetoreply, so their stats take days off into account.

   

4. Sign in to Microsoft 365 with your admin account and accept the permissions.

5. Back in timetoreply, tick the mailboxes you want to add.

6. Click Save Mailboxes.

Disconnect the admin account

To remove the admin account used for bulk adding:

1. Click your name in the bottom-left corner and select Settings.
2. Go to Advanced Settings → Microsoft Credentials.
3. Find the admin account under Credentials for and click the trash icon.
