GSSMO events in Outlook
When using G Suite Sync for Microsoft® Outlook® (GSSMO), here are some miscellaneous (and mostly minor) differences in Outlook Calendar, when sending invitations, updating events, working with recurring events, or changing time zones.
- Invitations from Google Calendar don't show all attendees: If you receive a meeting invitation in Outlook from a Google Calendar user, you won't see all attendees in the invitation email. You will, however, see all attendees in your calendar.
- People can't always accept forwarded meeting invitations: If you forward a meeting invitation in Outlook to someone who accepts the invitation (by clicking Accept in your email), the event might not be added to the recipient's calendar. This happens if the meeting organizer created the meeting in Google Calendar and unchecked the "Guests can invite others" option.
- Requesting invitation responses: If you create a meeting in Outlook and choose not to receive responses from attendees (you don't select the Request Response option), you might still receive responses. This happens if you have enabled Notifications for your calendar in your Google Calendar settings.
- Minor event updates are marked as exceptions: If you update an event in G Suite without changing the time or location, for example, by adding a comment, the event in Outlook appears as an exception (the exception icon is shown), even though it really isn't.
- Event replies aren't stored in Calendar: When you reply in Outlook to a meeting invitation, you can edit your reply before sending. Your reply is indeed sent via email. But it's not stored as a note in the calendar event itself.
- Resource names don't update for previously scheduled events: If your domain administrator changes the name of a conference room or other resource, Outlook users don't see the new name for meetings that have already been scheduled. They will, however, see the new name when attending or scheduling any future meetings.
- Maximum number of recurrences: With G Suite, a recurring event is limited to 365 recurrences. If you import a daily recurring event from Microsoft Exchange that was scheduled January 1 2005, the event will stop recurring January 1 2006.
- Scheduling a recurring event: If a Google Calendar user schedules a recurring event that begins on a different day than the meeting recurs, Outlook users don't see the first event. For example, if a Google Calendar user schedules a weekly meeting for Monday that recurs every Tuesday thereafter, Outlook users will miss the first meeting. (This is because in Outlook, you can't schedule a recurring meeting that begins on a different day than the remaining series.)
- End-of-month recurring events: If a Google Calendar user creates a recurring event on the 31st of every month, Outlook users will see events on the last day of every month (even those with only 30 days). Google Calendar users, however, will see events only in months with 31 days, as the organizer likely intended.
- Modifying recurring events doesn't delete exceptions. If you modify a recurring event in Outlook, existing exceptions aren't necessarily deleted even though a dialog says they will be. So if you schedule a weekly meeting at 2pm, move this week's meeting to 1pm (creating an exception), then reschedule the entire series to 3pm, this week's meeting will still be at 1pm. (In Exchange, this week's meeting would be moved to 3pm.)
- You can't remove attendees from an exception. Removing an attendee from an exception to a recurring event, doesn't always remove the attendee.
- Declining a recurring event from Outlook 2003: If an attendee using Outlook 2003 declines an invitation to a recurring event organized by an Outlook 2007 user, the 2003 user is removed from the organizer's attendee list, rather than just listed as declined.
- Moving an all-day recurring event: If you schedule a recurring all-day event, such as a daily Out of Office event for a week-long vacation, then move one recurrence to another day that's part of the series (say, you move Monday's event to Tuesday), Outlook will still allow only one event on Tuesday. A Google Calendar user, however, sees two all-day events on Tuesday.
Time zone changes
- New time zone rules can affect meeting times: G Suite uses current time zone rules to do UTC-to-local time conversions, not those that apply when the event is originally created. This can affect meeting times in regions where time zone rules tend to change. For example, if you create a 2pm meeting in New Zealand when the time zone is GMT +13, and New Zealand's time zone subsequently changes to GMT +12, the meeting will now show up at 1pm.
- Choosing a new time zone affects all-day events: Unlike in Exchange, if you have an all-day event on your calendar in G Suite, then change your time zone, the event is still shown as an all-day event. In Exchange, by contrast, the event becomes a 24-hour event that crosses day boundaries.
