Cannot access account neither email

Hi, @Yulia11,

 The volunteers in the Zoom Community don’t have access to account information or ability to make changes to accounts. Please submit your request via a Support Ticket to Zoom staff at:
https://support.zoom.us/hc/en-us/requests/new 

To make sure your Internet connection is working properly, restart your modem, get the latest router firmware updates, and switch to a cable connection if that's possible given your current configuration. Then, check your firewall and antivirus settings and ensure none of them is blocking Zoom or certain Zoom features.

Also, to change password you can follow below steps:

Sign in to the Zoom web portal.
In the navigation menu, click Profile.
Under Sign In, click Edit next to Sign-In Email.
Enter the new email address.
Enter your password (for accounts with work email sign-in method).
Click Save Changes.

Regards,
James
