How to "access it using web interface first."

I’m sorry… this may be a really, really stupid question.

But on this site:…

It tells me: Be aware in order to use your calendar account you have to access it using web interface first.

How do I do that?? I just don’t understand… its probably very simple, but I really want my calendar to sync up! I just can’t seem to get rid of sync errors.

Help? and Thank you!

open your web browser, enter the following address:, enter your Google Account email and password, and click Sign in. That’s it!

oh. Well, that is sort of what I thought. it didn’t work. I’m still getting the following error: Synchronizing calendar ' Calendar/" failed with an error: Specified cast is not valid.

Have you any ideas on that error?

thank you for the reply!


please download and install the latest version of eM Client… and let me know if it helps.

Unfortunately that did not help. I tried deleting the account and re-adding it as well. :frowning:

Yay! I got it working. :slight_smile: I had recently started over with my OS and then tried using this email client. since my last reply to this thread, I realized I didn’t have any service packs installed for Windows. I got it up to date and the calendar is syncing beautifully. Thanks for the replies! Maybe this will help someone else.
