Sign in to Mary

Sign in using your work account and your firm's Mary region. If sign-in works but the organisation or matter you need is missing, follow Get access to Mary and shared matters.

Open the correct sign-in page

Use the link supplied by your firm, or the relevant regional sign-in page:

• Mary Australia

• Mary United States

Choose your firm's usual sign-in method and complete any required authentication. If your firm uses more than one Mary organisation or environment, confirm which one contains the matter you need.

Once you can open the intended matter, follow Get started with Mary to find its documents, ask a first question and return to the result.

An invitation does not work

Check that the invitation names the intended organisation and was sent to the account you are using. Ask the organisation administrator to check an expired or unusable invitation and arrange a replacement. Use the intended invited account rather than creating another account to work around the error.

Microsoft or another identity provider blocks access

Record the exact error and ask your firm's IT administrator to check your access to Mary.

For example, AADSTS50105 means Microsoft Entra requires application assignment and the user lacks an assignment that grants access. IT should review the user's or group's assignment under the firm's access policy. Microsoft provides specific guidance for AADSTS50105.

Use the guidance for the error actually displayed. Resetting a password does not resolve a missing application assignment.

You can sign in but cannot see a matter

Check the organisation and matter name, then follow Get access to Mary and shared matters to arrange sharing.

If the matter opens but a tool or view is missing, follow missing features and display issues.

Sign-in loops or stays unfinished

Look for an authentication window or tab waiting for input. Complete the intended sign-in, then return to Mary. Preserve any unsaved work before closing or refreshing application pages.

If the problem continues, contact Mary support with the region, organisation, intended account, time and exact error. State whether you cannot sign in at all or cannot see a particular matter. Enter passwords and verification codes only in the sign-in flow.

For changes to organisation membership or responsibility for matters, follow Get access to Mary and shared matters.
