The PST created having calendar entries is not getting imported to Office 365

Hi Team,

We are building the PST from defined source which is having Email , Calendar ,Contact and Task data in it.
This PST is expected to get upload to Office 365 using Import functionality of Office 365.
Email , Task works properly but when we go for calendar it shows skipped (Corrupt).
Do you came across with the same concern raised to you ?
There are few observations in it.
If we are not setting recurrence then it gets import properly.
If we export the same file from outlook and create another PST then it get import correctly.


Please use the latest version of Aspose.Email for .NET 22.2.0 and let us know how it goes on your side. Hope this helps you.

Yes. I have checked with the latest version as well and ended with the same result.
