Hello Alex, and thanks Jordan!
We don’t just yet support convenient use of multiple AxCrypt accounts in a single Windows sign in session but it’s planned. Currently the easiest way to work around this limitation is to do File | Options | Clear All Settings and Exit, then type the email again.
Another note if you’re actually sharing one Windows log in with several people using TeamViewer. TeamViewer has become a very popular vector for breaking into computers and encrypting files for ransom. Do make sure that you have a very strong password on the system and that all users are aware of the necessity to keep that password secret.
