Important Full product retirement for Salesforce for Outlook is scheduled on January 30, 2027. See [Salesforce for Outlook Retirement](https://help.salesforce.com/s/articleView?id=000393445&type=1&mode=1&language=en_US). To keep integrating Microsoft Outlook with Salesforce, check out our next-generation products: the Outlook integration and Einstein Activity Capture. See [Move from Salesforce for Outlook (Retiring) to the Next-Generation Products](https://help.salesforce.com/articleView?id=outlookcrm_sfo_move_parent.htm&language=en_US).

Salesforce for Outlook syncs recurring events, which are repeating events created in Salesforce Classic). It doesn’t sync event series, which are repeating events created in your Outlook calendar, Lightning Experience, or the Salesforce app). To sync event series between your Outlook calendar and Lightning Experience or the Salesforce app, consider [migrating to Einstein Activity Capture](https://help.salesforce.com/s/articleView?id=sales.outlookcrm_sfo_move_parent.htm&type=5&language=en_US).

If you’re set up to sync recurring events using Salesforce for Outlook, you can sync recurrences with these patterns. After you sync recurring events to Salesforce, you can relate these events with Salesforce records, including contacts, accounts, and opportunities. Syncing recurring events also helps you maintain an accurate view of your availability when you create events and request meetings from your Salesforce calendar.

- Daily
- Weekly
- Monthly
- Yearly

Recurring events don’t appear on the My Unresolved Items page. Instead, go directly to the recurring events in your calendar and use the side panel to associate the recurring events with Salesforce records.

## Differences Between Outlook and Salesforce Classic Recurring Events

Recurring events work differently in Outlook than they do in Salesforce Classic.

                Salesforce for Outlook automatically adds another group of occurrences, bringing the total
                future occurrences up to 100 again. The schedule on which Salesforce adds these groups
                depends on the number of occurrences that passed and when you last synced, as well as
                whether you changed any existing occurrences.</p>

## Modifying Recurring Event Series

You can modify recurring event series, but it's good to know what to avoid, so that you don't lose any details for individual event occurrences that you've modified.

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small ">
        <colgroup>
          <col style="width:21.89054726368159%">

            <th scope="col" class="slds-cell-wrap" style="vertical-align:top;" id="d172333e259">If you modify</th>
            <th scope="col" class="slds-cell-wrap" style="vertical-align:top;" id="d172333e262">You should know that</th>
          </tr>
        </thead>
        <tbody>
          <tr class="">
            <td data-label="If you modify" class="slds-cell-wrap" style="vertical-align:top;" headers="d172333e259 ">Recurring event series in Outlook</td>

            <td data-label="You should know that" class="slds-cell-wrap" style="vertical-align:top;" headers="d172333e262 ">
              <p>Modifications are handled differently depending on which fields you modify. </p>
              <p>Changes
                to some fields are considered to be critical changes. If you make critical changes to your
                recurring event series, the critical changes are given preference to modifications that
                you’ve previously made to individual event occurrences, and the changes you make sync with
                Salesforce. Critical changes to recurring events include modifications to:</p>
              <ul>
                <li>Appointment times (StartDateTime, Duration)</li>
                <li>Recurrence patterns (RecurrenceType, Instance, Interval, DayOfMonth, DayOfWeekMask,
                  MonthOfYear, DayOfWeekIndex)</li>
                <li>Ranges of occurrences (Occurrences, EndDateOnly, EndKind)</li>
              </ul>
              <p>For example, if you modify the appointment time of a series, then later modify the
                appointment time for an individual event, the series appointment time modification
                propagates to the individually modified event, and syncs to Salesforce.</p>
              <p style="margin-bottom:0;">On the other
                hand, non-critical changes (changes to other event fields) that you make to a recurring
                event doesn’t propagate to individually modified events. Likewise, the non-critical changes
                that you make sync to Salesforce for the recurring event, but the individually modified
                events don’t sync.</p>
            </td>

          </tr>
          <tr class="">
            <td data-label="If you modify" class="slds-cell-wrap" style="vertical-align:top;" headers="d172333e259 ">Start dates for recurring event series in Outlook</td>

            <td data-label="You should know that" class="slds-cell-wrap" style="vertical-align:top;" headers="d172333e262 ">Salesforce doesn't support modifications to start dates that already occurred.</td>

              occurrences within the series. Those modifications don't propagate to Outlook. You can,
              however, modify end dates in Outlook, but that type of critical change clears all
              modifications you've made to individual occurrences—in both Outlook and Salesforce.</td>

                <li>You can lose those changes if you make critical changes to the recurring event
                  series.</li>

                <li>If you delete an individual event from a series, and then move the following occurrence
                  of that event into its place, Salesforce for Outlook doesn't sync that update to
                  Salesforce. Instead, the event that you deleted in Outlook remains in Salesforce along
                  with the event that you moved into its place.<p>For example, you change your recurring
                    event in Outlook. You delete the October 4 occurrence, and move the October 5 occurrence
                    into its place. In Salesforce, you'll see two occurrences on October 4: the one you
                    deleted, and the one you moved into its place. For October 5, you'll have no
                    occurrences.</p>
                </li>

                <li>Outlook modifications propagate to individual events in Salesforce, regardless of
                  whether the ones in Salesforce include critical modifications. Deleted occurrences in
                  Salesforce, however, remain deleted, and aren't replaced with individually modified
                  occurrences from Outlook.</li>

              </ul>
            </td>
