This video shows the steps to change your SMTP server password for Outlook version 15.24 for Mac after you change your Duck ID password. Here are the written instructions. When the Conditional Formatting window pops up, highlight the Unread messages option, and click the Font button to change the font and its color. Much like the font format option in Microsoft Word, the Font window in Outlook allows you to change the font, font style, size and even the color of the text.
I have had an Outlook 365 account for several years, which I have used for email, contacts and calendar in Outlook for the Mac (and Outlook 2013/16 on my Windows machines, first 7 and now 10), beginning in Outlook 2013 for the Mac and which migrated properly to Outlook 2016 for the Mac. Up to now, this has been seamless, far superior to the Mac Mail/Contacts programs and allows me to use bot Mac and Windows platforms interchangeably.
I recently added a second Outlook 365 exchange account, which I want to set as my new default email, contacts and calendar in Outlook 2016 for the Mac. and for Windows. This was easy to change on the PCs - just change the default data file in Outlook/Account Settings to the new exchange account, and all work like a charm in Outlook 2016 for Windows. I have also copied all my contacts and calendar entries and Outlook folders from the old exchange account to the new exchange account, as I want to use the original exchange account only for occasional emails, but not for any other functions.
However, this has been a challenge in Outlook 2016 for the Mac. I have changed the new exchange account to be the 'default' account in Outlook 2016 for Mac/Preferences/Accounts. However, this has not changed the default Calendar to the new account. Rather, all new appointments made on or through the Mac are being saved to the old calendar. My Mac OS is OS X El Capitan, in case that is important.
Please let me know how to change the default Calendar in Outlook 2016 for Mac to a new exchange account.
