hotmail.com calendar cannot be syncronized anymore after update 10.4.5326 (97a2e75)

Hello, just updated to 10.4.5326 (97a2e75) and calendar sync with hotmail.com doesn’t work anymore.

[AirSync] Die Synchronisation des Ordners’rsaelzer@hotmail/Kalender’ ist fehlgeschlagen mit folgendem Fehler: The input string ‘’ was not in a correct format.

Version 10.4.4867 (a1d5549) still works fine …

Can anybody help?

Hi, we’d like to see diagnostic logs capturing this:

  1. Go to Settings > Advanced.
  2. Enable logging for AirSync under the affected account.
  3. Restart eM Client.

After the error reappears:

  1. Go to Help > Open Log Directory in the menu and locate any new files with AirSync in the name.

You can either DM it to me or send it to [email protected]

Hello Kim,
I’m still facing a problem with synchronization of my hotmail calendar. There is no error message, but sync doesn’t work from eM-Client Version 10.4.5360 (8677c88) to cloud. The other way from cloud to eM-Client works fine.
