Office 365 (Known Issues) - AdBlock Browser Add-on Rejecting Messages in Safari

Individuals report they do not receive emails and/or receive a failed delivery report after sending an email. This problem is related to a bug in the Safari web browser add-on called "AdBlock". AdBlock appends additional code to Office 365 emails, causing many spam filters to flag messages as spam. This is not an Office 365 bug.


Resolution Status: Unresolved. AdBlock is aware of the issue and working on implementing a fix. Please see their support site for more information.


Disable the AdBlock browser add-on, use a different web browser, or Mac OS X configuration to connect to Office 365.
