Exchange Online calendar sync tool
We have developed software that synchronizes Exchange calendars. For the past few months, we have been facing a new problem that we did not have before. We synchronize calendar entries based on the LastModifiedDateTime attribute of the Microsoft.Graph.Event class.
We are puzzled by the fact that this attribute magically changes without any adjustments on our part.
Do you have any advice on this?
The items might have been updated by some background process, it's not that uncommon for Exchange Online. Just in case, check the audit logs, there might be something visible therein. Other than that, best open a support request so the relevant team can (hopefully) take a look at this.
