Calendar Best Practices

Please follow this list of Best Practices for the Exchange Calendar.  Click on each link to read more about it.

Send updates when deleting, canceling, or moving events

 If you do not send updates as a meeting organizer, attendees will not be informed of the changes.

Do not make personal notes in meetings as an attendee.

 As a meeting attendee, avoid adding your own private notes to the body of a meeting request in your calendar. If the organizer updates the meeting, your notes are lost.

Use the same Outlook version when multiple users are working on the same calendar (for example while using delegation)

When working with calendar delegates in Catmail, make sure everyone is using the same version of Outlook.  Editing a delegate's calendar from different versions (i.e. 2010, 2011 and 2013) can have undesirable results.

Always process meeting invites from the Inbox folder.

We recommend the user to process the meeting from Inbox and to avoid deleting this message before processing the meeting. Deleting the meeting request message from Inbox, before manually processing the meeting, will delete also the "tentative" meeting from your calendar. Once the meeting is processed using the meeting invite message, you will see that the meeting will change from "Tentative" to "Accepted"

We recommend processing the meeting request (by accepting/declining/etc.). This will inform the meeting organizer about your presence in the meeting or not (if you decline). The same principle applies with updates for already accepted meetings. Leaving the meeting as Tentative without processing it will potentially create conflicts and the information in your calendar won't be accurate.

If you receive a meeting cancellation message, open the message and click on the "Remove from Calendar" button. Doing so will ensure the meeting is removed from your calendar, and will help to avoid a situation where the meeting is cancelled but still appears in your calendar.

Do not delete meetings from your calendar.

Once you accepted a meeting and you are no longer able to participate do not delete the meeting from your calendar, decline it!

Also if you are not able to attend to a meeting at the proposed time you can always use the "Proposed New Time" feature of Outlook in order to inform the organizer. Note: You will not receive any meeting updates for a meeting you declined.

How to move or cancel a meeting.

  1. - If you are the meeting organizer:
    • Move a meeting. If you want to move a meeting, make your changes and make sure that you use the "Send Update" button in order to inform all attendees.

    • Cancel a single meeting. If you need to cancel a meeting, it is considerate to notify the people you invited. Delete the meeting from your calendar, click Send cancellation and delete meeting, and then send the cancellation to everyone you invited.

    • Cancel recurring meeting. If you, as the meeting organizer, are ending a recurring series of meetings, open the meeting on your calendar, set a new end date, and then send an update. This keeps the past meetings on everyone's calendars, but future occurrences after the end date are removed.


Don't move meeting requests.


Don't move a meeting request from your Inbox to a different folder before you accept or decline the request or before the meeting appears in your calendar.

Soon after a meeting request arrives in your Inbox, a piece of Outlook code - nicknamed the "sniffer" - automatically adds the meeting to your calendar and marks it as tentative. This is a fail-safe to keep you from missing the meeting in case you don't see the request in your Inbox. However, the sniffer doesn't reply to the meeting organizer. You still need to do that by accepting, accepting as tentative, or declining the request.

If you or a rule that you create moves an incoming meeting request from your Inbox before the sniffer can process the request, the meeting never appears in your calendar, and you might miss the meeting.

Recurring meetings.

In order to have a recurring meeting you will need to add a recurrence for it. This means that the meeting will take place according to the frequency you set (Daily/Weekly/Monthly/Yearly). You also have the option to set the range of recurrence starting from (Start field) to:

  • No End Date

  • End After: number of occurrences

  • End By: here you can enter a date

We recommend always setting an "End Date" for a recurring meeting. Failing to do so can result in corrupt meetings if the recurring meeting is regularly modified.

Do not frequently change recurring meetings

Meetings can easily become lost, mis-scheduled, or duplicated within a client after repeated updates. If a recurring meeting regularly changes time or location, cancel the meeting for all attendees and create a new meeting per occasion.

Deleting a recurring meeting as organizer.

Do no delete the meeting from your calendar. In order to delete a recurring meeting you will need to open the series (if you open the occurrence you will cancel only that occurrence) and click on the "Cancel Meeting". The next step is to send this information to all attendees in order to update also their calendar. To do this, use the "Send Cancellation" button. Attendees will receive in their Inbox the "Cancellation" message and will have the possibility to remove the meeting from their calendar (with the Remove from Calendar button). Important: All occurrences for the meeting will be deleted

To delete new meetings but preserve old meeting entries, open the series and change the "end by" date to a date prior to to the next meeting in the series.


Changing the organizer of a recurring meeting.

It is not possible to change the organizer of a meeting or recurring meeting. The original organizer should send an update with a new end date. This way the past meetings remain on everyone's calendars, but future occurrences after the end date are removed. The new organizer should send a new request for meetings in the future.

Recurring Meeting Exceptions.

A recurring meeting exception is in fact an occurrence that is modified (date/time). An exception will no longer correspond to the recurrence pattern. Be careful when modifying an individual instance of a meeting, as the global changes will wipe out.

Create meetings on Exchange.

In order to view your calendar data from both Outlook and OWA, you need to store your data (calendar items, messages, etc.) on the Exchange server. When creating new events, be sure to create them with your Exchange account calendar selected, not the calendar labeled "Calendar [On My Computer]" To move an event from one calendar to another, highlight the event and select Event from the menu bar, then Move To or Copy To and Choose Calendar.

Using an Smart phone.

Respond to all meeting requests that are in the inbox. Do not delete the request, even if you are sure you responded to it in Outlook on your computer. Doing so can cause the meeting to be deleted, and a response will not be sent to the organizer, leading them to believe that you are still attending.  

Do not use your phone to respond to meeting requests unless you have to. Aways either accept or decline a meeting invitation using the "Send a response" or "Edit the response" options. Do not use the "Do not send a response" option.

Only interact with meeting requests from one client.

Due to the different methods of synchronization by various clients, it is easy to have multiple or conflicting replies to a single request which will result in a deleted or otherwise corrupted calendar entry. Only interact with meeting requests once, whether it be from Outlook, Entourage, a BlackBerry, iPhone, Outlook Web Access (OWA), or other clients. If you must use other clients, follow the best practices.
