This is on Outlook 2016 MSI version connected to office 365 exchange.
When I type my personal email address xxxx12334@gmail.com it is then linked to my work email account with presence, the skype presence box is shown next to my personal email address. It doesn't change it to my display name however.
When I send the email it shows up in my work inbox. It's very annoying.
I've deleted the prefill email address in the dropdown, I've searched my address book and deleted any entries for my personal email address. I've looked for linked accounts in office 365 and there are none. I'm not sure where and how outlook is linking my personal email address with my work account. I've never associated my personal email with anything work related on any of my computers.
Any other suggestions? Thanks in advance!
