Hi, on my Z2 I have the Outlook app. Almost every day in stead of synchronising the app says it's loading. When it does that I cannot use the app. The only way to make the app work again is to force the app to stop and after that clear it's cache. Very annoying and I hope you have a solution for this. Thnx!
That's an app bug/issue that has to be addressed by microsoft developers, do contact them, also uninstall and re-install the app. Btw, do you have any antivirus or taskiller app?
