What Office 365 Domain Names to Exclude from Filtering?¶
The following domain names are currently recommended by our team to be excluded from web filtering, HTTPS decryption and proxy authentication to ensure normal functioning of Microsoft Office applications through explicitly set HTTPS decrypting, Active Directory integrated proxy (Squid, Web Safety).
.microsoft.com .microsoftonline.com .office.com .office365.com .windowsupdate.com
To add these domain names, navigate to Admin UI / Squid Proxy / Exclusions / Domain Name and add them one by one. Please note the dot at the beginning of each domain name, it implies the domain name and all its subdomains will be excluded.
