How do I add a second mail account (Gmail) to OS 10.3 (Q10)?

I want to use 2 mailaccounts. The first one (workmail) is already working and uses the ActiSync feature to sync my Mail/Contacts/Calendar etc. If I want to add a second mailaccount I cannot use a gmail mailadres. Mail from outlook.com is no issue, but Gmail is. I also tried to add outlook.com and later on change the settings to my gmail account, but then I get the message that this isn't possible right now.

My goal is to use both account for contacts, calendar and mail ofcourse.

I am using a BlackBerry Q10 with OS 10.3 (10.3.1.745).

I don't know what's going on on your end, pal. Here I have 5 email accounts here, one being an Outlook.com and two Gmail - both syncing all the stuff.

All you should have to do is Settings > Accounts > Add account > Gmail and enter your data....

If that is messing up accounts already on your device, I'd talk to the IT guy and see what is going on.

I honestly have this issue for several months now. But today it worked.

I updated to the latest leaked firmware, installed with Sachesi and added the Gmail account first. After that my work account and everything works like a charm!
