​
Accept your MessageDesk invitation

You’ll receive an email from MessageDesk with a Join the Team button. Click Join the Team to open the sign-in page and complete your account.
Log in or create an account using the exact same email address that you were invited with (usually your work email). If you sign up with a different email, you’ll create a separate workspace.

​
Create your user account (as an invited user)

You have two ways to finish the setup:
  1. Sign in with email: we’ll send a one-time 6-digit code to your mobile phone and email. Enter it to continue.
  2. Sign in with Google: no codes required. Approve with your Google account.
After you complete account creation, you’ll land directly in your team’s workspace.
Enter a valid personal mobile phone number when logging in via email. This phone number is for authentication and login only. It’s separate from the phone numbers associated with your MessageDesk workspace.

​
Log in and complete two-factor authentication

  1. Confirm sign up via SMS by entering the 6-digit code sent to your personal mobile phone.
  2. Confirm sign up via email by entering the 6-digit code sent to your email address.
Didn’t receive an SMS? Double-check that you entered a valid mobile phone number. You can also click Send Code to resend the code to your number.
Didn’t receive an email? Double-check your spam/junk folder and look for an email from noreply@messagedesk.com

​
Join multiple workspaces

You can be a member of multiple MessageDesk workspaces. If you already have a MessageDesk account:
  • Clicking a new invite opens the workspace selection screen with workspaces you’ve been invited to.
  • Workspaces are grouped by tenant (the parent company account), so you can quickly tell which company each workspace belongs to.
  • Choose the workspace you want to join.
Switching between workspaces is quick. Open the workspace switcher (top-left or profile menu, depending on app view) and select the workspace you need.
Tenant admins can also create new workspaces directly from the workspace selection screen. See Tenant Management for details.

​
What happens next

  • Your admin sets your access through roles and permissions (Admin, Manager, Operator, or a custom role).
  • You’ll see the Inbox, can view or send messages according to your permissions, and (optionally) receive notifications once configured.
  • If you don’t see expected phone lines or labels, your role may limit access. Ask an admin to adjust.

​
Troubleshooting

Didn’t receive the invite email?
  • Check spam/junk and any security/quarantine filters.
  • Confirm with your admin that the email address is correct.
  • Ask IT to allowlist messagedesk.com, then have the admin resend the invite.
Invite link expired or not working?
  • Ask your admin to resend the invitation from Settings → Team Management.
  • Try opening the link in an incognito/private browser window.
Signed in with the wrong email by accident?
  • Log out, then sign in again using the exact email you were invited to.
  • If you created a new workspace by mistake, your admin can resend the invite to the correct address.
Getting “Invalid session for the user, session expired.”? I joined, but don’t see Team Management or certain phone lines.
  • Your role may be Viewer on those features/lines. Ask an admin to review your role and any resource-level permissions.
Can I switch between email/password and Google sign-in?
  • If you already have an account created with an email/password, you can sign in with Google (using the same email). MessageDesk will link your Google identity to your existing account.
  • If your account was created with Google first, you must continue using Google to sign in. You can’t add email/password login to a Google-first account.
