Reporting datasetContacts Proposed contact table in SQL Server (choose its name)
Plan a contact dataset while preserving its source meaning.
- Microsoft 365
- Object support to establish
- SQL Server
- Your database schema
Record identity
Use a stable person/contact ID and an explicit cross-system lookup. Email can change and can be shared, so treat it as a matching clue rather than a universal key.
Field ownership
Keep consent and communication preferences under an agreed authority; a general contact update must not silently resubscribe someone.
Fields to include
- Source person ID
- Display name
- Email address
- Organization reference
- Consent state
Reporting datasetUsers Proposed application user or identity table in SQL Server (choose its name)
Plan a application user or identity dataset while preserving its source meaning.
- Microsoft 365
- Object support to establish
- SQL Server
- Your database schema
Record identity
Use the immutable user ID within the tenant or directory. Do not equate an application user with a CRM customer contact.
Field ownership
Identity and application owners approve account lifecycle and access changes; synchronize only approved attributes.
Fields to include
- Source user ID
- Tenant reference
- Account status
- Group references

Architecture decision
Choose how to connect your systems
Choose a method around one example record and the update your business needs. Use Contacts / Proposed contact table in SQL Server (choose its name) to review record matching and confirm Stacksync support for the required operations. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.
Stacksync managed sync
- Best fit
- Review compatibility with a Stacksync engineer using an example of the records and updates you need.
- Operating responsibility
- Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
- Before you choose
- Check record matching: Use a stable person/contact ID and an explicit cross-system lookup. Email can change and can be shared, so treat it as a matching clue rather than a universal key. Verify field coverage, deletion handling, and how changes are detected.
Native vendor integration
- Best fit
- A vendor-built integration may fit if it supports your Microsoft 365 and SQL Server record types.
- Operating responsibility
- Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
- Before you choose
- First check whether either vendor offers this integration. If available, verify Contacts / Proposed contact table in SQL Server (choose its name), update direction, account tier, and related-record handling.
Custom API or workflow
- Best fit
- Consider when Microsoft 365 and SQL Server need a transformation, approval, or action outside a direct record sync.
- Operating responsibility
- Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
- Before you choose
- Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery.
File or scheduled snapshot
- Best fit
- Consider for a one-time Microsoft 365 / SQL Server migration or a reporting need with an explicit freshness window.
- Operating responsibility
- Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
- Before you choose
- Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.
Workflow reference
From a business event to the right update
Open a workflow to see its trigger, record relationships, and expected result.
Contact reporting workflow
Starting event: A change to the selected Contacts or Proposed contact table in SQL Server (choose its name) record needs a defined result in the other system.
- Start with Microsoft 365 Contacts and SQL Server Proposed contact table in SQL Server (choose its name). Use the record-matching and field-ownership rules from your mapping worksheet.
- Resolve the organization relationship and any owner or consent references required by the destination.
- Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.
Expected result: Test an email change, two records sharing an email, and a person associated with multiple organizations.
If it fails: Hold ambiguous matches for review and reconcile the person ID before retrying; preserve the consent decision already recorded by its owner.
Application user or identity reporting workflow
Starting event: A change to the selected Users or Proposed application user or identity table in SQL Server (choose its name) record needs a defined result in the other system.
- Start with Microsoft 365 Users and SQL Server Proposed application user or identity table in SQL Server (choose its name). Use the record-matching and field-ownership rules from your mapping worksheet.
- Resolve tenant and group references and establish a protected administrative-account policy.
- Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.
Expected result: Test a renamed login, disabled account, missing group, and a user existing in two tenants.
If it fails: Review access impact before retrying a lifecycle change; reconcile current identity state and retain an approval trail.
Task or work item reporting workflow
Starting event: A change to the selected Planner & To Do Tasks or Proposed task or work item table in SQL Server (choose its name) record needs a defined result in the other system.
- Start with Microsoft 365 Planner & To Do Tasks and SQL Server Proposed task or work item table in SQL Server (choose its name). Use the record-matching and field-ownership rules from your mapping worksheet.
- Resolve project, user, and parent-item references before the task.
- Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.
Expected result: Test a reassignment, an unsupported status transition, a deleted parent, and a due date across time zones.
If it fails: Reconcile the destination state before retrying a transition to avoid reopening completed work.
Define an explicit handoff between Microsoft 365 and SQL Server
Starting event: A business event involving Users or Groups needs a defined response involving a selected destination dataset.
- Document what the source event means and which destination record or action should respond. A similar name does not establish a shared entity.
- Retain separate IDs and choose whether the destination is a report, a new work item, or a change to an existing record.
- Assign an approval owner and a duplicate-detection rule before running an action. Use a custom workflow only after its endpoint support is confirmed.
Expected result: An example input has an unambiguous destination and expected result; repeated delivery produces only the intended change.
If it fails: Resolve missing identity or ambiguous business meaning before retrying; route unsupported operations to the implementation owner.
Production readiness
Test the behavior your business depends on
Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.
Contacts / Proposed contact table in SQL Server (choose its name)
Test case
Test an email change, two records sharing an email, and a person associated with multiple organizations.
Expected result
The expected contact relationship is preserved with no duplicate action or unintended write.
Users / Proposed application user or identity table in SQL Server (choose its name)
Test case
Test a renamed login, disabled account, missing group, and a user existing in two tenants.
Expected result
The expected application user or identity relationship is preserved with no duplicate action or unintended write.
Planner & To Do Tasks / Proposed task or work item table in SQL Server (choose its name)
Test case
Test a reassignment, an unsupported status transition, a deleted parent, and a due date across time zones.
Expected result
The expected task or work item relationship is preserved with no duplicate action or unintended write.
Mail Messages / Proposed message or conversation table in SQL Server (choose its name)
Test case
Test a delivery-state change, repeated message, private conversation, and reply linked to the correct thread.
Expected result
The expected message or conversation relationship is preserved with no duplicate action or unintended write.
Direction and permissions
Test case
Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.
Expected result
Only an approved, supported direction and permitted fields are written.
Freshness and reconciliation
Test case
Measure source and destination times for the selected records under normal load and a burst. Reconcile IDs and values using the same filters and cutoff.
Expected result
The process meets its agreed freshness target and reconciliation has no unexplained differences.
Failure recovery
Find the cause. Restore the data flow.
Start with the failed record and the destination error, then inspect the source value, field requirements, and access.
Rejected or repeated contact change
Investigate
Inspect Microsoft 365 Contacts and SQL Server Proposed contact table in SQL Server (choose its name), their IDs, and the destination error.
Next action
Hold ambiguous matches for review and reconcile the person ID before retrying; preserve the consent decision already recorded by its owner.
Rejected or repeated application user or identity change
Investigate
Inspect Microsoft 365 Users and SQL Server Proposed application user or identity table in SQL Server (choose its name), their IDs, and the destination error.
Next action
Review access impact before retrying a lifecycle change; reconcile current identity state and retain an approval trail.
Rejected or repeated task or work item change
Investigate
Inspect Microsoft 365 Planner & To Do Tasks and SQL Server Proposed task or work item table in SQL Server (choose its name), their IDs, and the destination error.
Next action
Reconcile the destination state before retrying a transition to avoid reopening completed work.
A record type or update is unavailable
Investigate
Check the Microsoft 365 and SQL Server connector guides, account permissions, and any operations marked On Request.
Next action
Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.
Source and destination disagree after a retry
Investigate
Compare current source values, destination validation, identity mappings, and any side effects already completed.
Next action
Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.
Read the Stacksync issues dashboard guide for retry and revert behavior.

Update timing and record limits
- Measure initial-load and ongoing-change latency separately. Source detection, selected objects, account limits, and destination validation determine the observed delay.
- Review write-back, deletion handling, update timing, and account limits with the integration team.
Prepare Microsoft 365 and SQL Server access
Set up both accounts before testing the mapping. Use test records where available, and identify the account administrator who can approve access and help resolve setup errors.
Microsoft 365 setup checklist
- Identify the Microsoft 365 account, edition, environment, and business objects the integration must access.
- Confirm a Stacksync connector or implementation path for Microsoft 365, including read/write support, authentication, and initial-load limits.
SQL Server setup checklist
- Use a single generated primary key per table and grant the Stacksync user the required table access.
- Have a DBA run the one-time CDC setup script and grant execution on its wrapper procedures. Verify SQL Server Agent where the deployment requires it.
Setup guides: Authorize SQL Server
Prepare to go live
Record the fields each system can update, the first-load cutoff, both record IDs, the expected update delay, and who handles errors. Complete the tests before production before expanding to more records.
Use the Microsoft 365 and SQL Server planning worksheet to capture these decisions. Record the access owner in the worksheet and enter credentials only in the connection setup.
FAQ
Microsoft 365 and SQL Server integration FAQ
-
Explore a Microsoft 365 and SQL Server integration with a Stacksync engineer. Stacksync support for Microsoft 365 is not established by the connector documentation reviewed for this page. Start with one record and the update your business needs to identify an implementation path.
-
Confirm two-way support with Stacksync for the records and fields you need in both systems. Access to a vendor API does not confirm that its Stacksync connector supports write-back.
-
Measure initial-load and ongoing-change latency separately. Source detection, selected objects, account limits, and destination validation determine the observed delay.
-
No. Stacksync documents that pre-existing duplicates are not merged automatically when two-way sync begins. Review the initial dataset and matching plan before enabling it; an empty destination can simplify the first load.
-
Start with one business entity and a stable record ID. Map a small set of editable fields with compatible types, test required values and relationships, then expand after the pilot passes.
-
Check the destination error, field constraints, permissions, and current source value. The Stacksync issues dashboard supports retry and revert; retry reads current source values, so verify the intended record state before acting.
-
Use the current Stacksync pricing page and confirm the supported implementation with the team. Scope the required objects, record volume, update frequency, initial load, and support needs when comparing a managed connector with native or custom development.
-
Start by reviewing Contacts in Microsoft 365 and Proposed contact table in SQL Server (choose its name) in SQL Server. Check how these records relate in your workflow, then confirm the actual fields and supported operations. Test record matching and one failed or repeated update before adding more records.
-
Choose a method around one example record and the update your business needs. Use Contacts / Proposed contact table in SQL Server (choose its name) to review record matching and confirm Stacksync support for the required operations. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.
-
Prepare both accounts, the selected object schemas, stable source and destination IDs, and the expected outcome. Identify the Microsoft 365 account, edition, environment, and business objects the integration must access. Use a single generated primary key per table and grant the Stacksync user the required table access. Use the pair worksheet to record ownership and acceptance criteria.
