In Detail
I’m not a fan of Outlook Office365 — or many Microsoft products for that matter. Sending and receiving emails from some other web-based email client using an Office365 email account is not very well documented nor is it explicitly stated as a possibility. There are plenty of guides on how to switch from Gmail to Office365, but finding a concise guide on the opposite was rather difficult to find.
Let us fix that right now.
Start by Logging into Gmail!
Click the gear icon in the upper-right-hand corner of the interface
Click “Settings” selection
Now click “Accounts and Import” tab.
Under the section named, “Send mail as,” select “Add another email address you own.”
Enter the email address that is currently using Outlook Office365.
Click “Next Step.”
In the next menu, enter under “SMTP Server”: smtp.office365.com
Port 587 worked for me, it was the first thing I tried, I would suggest starting there.
Enter your M$ username and password.
The only thing that seemed to work for me was to select the “TLS (recommended)” option.
Click “Add Account.”
Now after the window closes, with the “Accounts and Import” window active, select “Check mail from other accounts (using POP3).”
Enter the same email address as before.
Click “Next Step.”
Enter your Outlook Office username and password
Enter POP Server: smtp.office365.com
I selected “Leave a copy of retrieved message on the server” but it is optional.
Click “Always use a secure connection (SSL) when retrieving mail.”
Port 110 worked for me, it was the first thing I tried, I would suggest starting there.
“Label incoming messages: X” is also optional, but the labeling is a nice addition, thereby with a glance knowing where the email came from.
Click “Add Account.”
Everything should at this point sync up properly. If not, well shoot, tinker around with these settings to see if you can find that sweet spot. This worked for me as of Oct 2014.
With the exception of Calendar events, everything else I need works well. The only meaningful difference are the calendar events: instead of receiving a google calendar event, one will receive a link from M$ to their calendar application.
