If you are connecting a Hotmail account to Pet Sitter Plus via SMTP, your first attempt to connect might fail. This is normal.
All Hotmail accounts are hosted by Microsoft on Outlook.com. Since Microsoft introduced some additional security measures to protect your account, there are now some additional steps required to connect your Hotmail account via SMTP which are set out in this HELP page.
First - complete the SMTP credentials (see below) with your particular account details and then click “Test & Update”
To remedy the failed login attempt, there are generally two things you need to do.
Step 1 - Allow Access for new locations, devices and apps on your Hotmail account
Microsoft will send you an email informing you that they have detected unusual sign-in activity from a new location, device or app. If you can't see this email in your Inbox, please check your junk mail or if you have deleted it.
You will need to click on the blue button "Review recent activity" .

Step 2 - Allow access to your Microsoft Account
You will receive an email that looks like the one below.
You should see a blue button that says “This was me” and you will need to click this for every access attempt.

Retrying to Connect
Having completed steps 1 and 2 above, click “Test & Update” again and the connection attempt should now succeed.
An email is sent to the address you have stored in the “Email Address” field in
ADMIN > SETTINGS > Company Information.
You should receive an email that has the same code in the subject line as notified to you on the previous screen (see screenshot above). This confirms that SMTP integration is now working correctly.
