Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi @Sue Robertson ,
Are you Teams owner or member in Microsoft Teams?
Are there any error messages when signing in Teams client?
Do you have Teams subscription for you account?
If there is no issue before this issue happened, this issue may related to time zone. In this case, we recommend you go to control panel -> Time & Language-> Set time zone automatically OFF and select manually the time zone and then synchronized your clock. Then restart your computer to see if it can be fixed.
