There are currently ongoing issues for Office 365 customers using Server-side integration for Microsoft Outlook.
- Deletion of visits when SAP Cloud for Customer is connected to Office 365
- Synchronization was stopped by error (no data loss) when SAP Cloud for Customer is connected to Office 365
Cause:
- On Jan 16 Microsoft started to roll out Exchange Online version 15.20.2644.21 which has regressions compared to previous versions of Exchange Online and compared to Exchange 2013-2019 family.At the moment, two support requests are open and are escalated to Microsoft.
As updates to O365 take time to propagate, customers may have gotten affected anytime from 16-Jan-2020 and up to 19-Jan-2020 when issue was identified and synchronization for O365 users was suspended. Support cases: 18301130 18324425 are open with Microsoft with complete technical details provided
Action Taken by SAP:
- Synchronization is suspended for all users running Office 365 to minimize impact.
All non Office 365 users and Google mail users are synchronizing successfully with no impact.
- Ability to force synchronization is temporarily prohibited to all users in order to not trigger synchronization while investigation/resolution is in progress.
- In parallel to escalating support cases with Microsoft, the server-side development team is actively working on workaround solution.
There are multiple issues identified with O365 and they are being addressed in parallel.
Once development completes and we have completed a full round of validation, the patch will be deployed on all TEST and PROD landscapes and then Office 365 synchronization will be unblocked.
Recommendations:
For O365 users synchronization is temporarily suspended, and upon resuming will continue from the same state bringing records in sync.If there are pending changes – they will settle at that time, and if automatic sharing of calendars or emails is used – emails will be processed upon synchronization resume, so no information loss shall appear.
Next Steps and ETA:
- Upon resolution from Microsoft or availability of validated patch – whatever comes sooner, synchronization for O365 users will be unblocked.
Sync has been re-enabled on all TEST and PROD tenants as of 28-Jan-2020.
