Unexpected Room Approval Entries on Personal Calendars After Inky Implementation

 Problem

Users are experiencing an issue where room approvals for shared calendars are appearing on their personal calendars, even when the room calendar is deselected. This behavior has been observed after the implementation of Inky and was not an issue before.

The main issue stems from the message type being altered when it is sent through a connector for processing by INKY. While this isn't an issue that can be resolved directly, we can circumvent the problem by ensuring these specific types of messages are not sent through the connector.

 Solution

  1. Login to the Exchange Admin Center → Mail Flow → Rules

  2. Hit the “+ Add a rule” icon then “Create a new rule…”

  3. Set up the following parameters:

    1. Name: IPW Filter - Calendaring

    2. Apply this rule if: The message properties, include the message type, “Calendaring."

    3. Optionally: Include another apply clause such as a recipient filter to only bypass calendars for certain users.

    4. Do the following: Modify the message properties, set a message header.

    5. Set the message header “X-IPW-Ignore" to the value "True."

    6. If you need to add exceptions, then you can do so now.

    7. Hit “Next” then set the “Match sender address in message” to the appropriate requirements for your mail.

      1. Header - Least secure as the header from field can be spoofed

      2. Envelope - Most secure but may not match everything you need

      3. Header or envelop - Most broad but just as insecure as header only

    8. Hit Next → Finish

    9. Find the newly created rule in the list and select it then select “Edit Rule Settings”

    10. Set the priority to the number directly after the lowest current filter rule. In my example, the lowest rule is the “IPW Filter - Encrypted” rule at priority 11 so I’ll set this new rule to a 12. Then hit “Save”
