re : I select Google Calendar, It is asking for a Location -

I believe it says: 'Create new Calendar' 'Locate your Calendar' 'Please pick an existing session or enter your email address to create a new session. You only need one session per account'

The location is your gmail email address. That is where the calendar is located. In the text box type in your full gmail email address and then click on 'Next'.

General info on new calendar: https://support.mozilla.org/en-US/kb/creating-new-calendars#w_google-calendar_2

@Toad-Hall - thanks for your reply - I have reviewed the link you provided earlier but that is not what I am prompted to do when I select to create/add a new calendar.

I believe that have the two extension configured correctly.

https://support.mozilla.org/en-US/kb/using-lightning-google-calendar After downloading the provider google addon, I presume you then installed the addon into Thunderbird. All instructions at the above link. Did you then restart Thunderbird? If no, please restart Thunderbird.

I've posted two images. The first image sounds exactly as you mention and when clicking on the last 'Next', When the second image I posted appears, at the same time you should also get a pop up window to sign in to your [email protected] email address.

Do you get the google 'sign in to your account email address' window pop up at same time? Enter email address and click on 'Next' Enter Password click on 'Next' Confirm you did the above sign in.

You should then get a 'Provider for Google Calendar wants to access your Google Account. click on 'Allow' Confirm you got the request to allow google provider to access google account.

It is at this point the window in second image should now populate.

The second one will only show the blank text box if you do not have google calendar already previously added. In which case this is where you enter the gmail email address of the account and then click on 'Next'.

If you already have a google calendar added but wish to add other calendars you created in google then you would select your current email address to get the option to select to add them.

Here is what I see - which is completely different then images you have posted.

I see what you mean. What happens if you type in your gmail email address in the 'Location text field and then click on 'Next' ?

do you get a prompt by gmail to offer logon details?

The next button is not available when you enter in a gmail email address
