If you have received and validated an invitation to join another Mailify account, you have two options to access that shared account:
When you login, Mailify will systematically ask you, once you have entered your access codes, to choose the account you want to connect to.
Click on the arrow next to the name of your account to display the list of available accounts.
Select the account of your choice from the drop-down list, then click the "Confirm" button. You will be redirected to the selected account.
If you are logged in to your own user account, you can switch to the shared account from the menu at the top right of the application.
Click on the small arrow to the right of your account name and then click on "Change Account".
The list of available accounts (your user account and all the other shared accounts for which you have received and validated an invitation) is displayed. All you have to do is to select the account of your choice from the list.
Once you have selected the account, you will be redirected to it and will be able to see the resources that have been shared with you on this account.
