We hope that this post can help you fix your own app issues.
These are the specific topics mentioned here today: Hi there.
The fact that meeting invites aren't displaying in your calendar may be the result of a temporary glitch in Outlook.
Active directory has the correct info, and everything seems to be in place, our only issue is with the wrong name showing up in the shared Outlook calenders. I have frequently seen people change the CN (Common Name) of a user object, but not update the display Name attribute, or they do it the other way resulting in a user that is only half-way renamed.
Since you have already tried to factory reset, the next best thing to try is booting the phone in safe mode.
This is especially helpful if you simply re-install your apps after a factory reset without observing the device thoroughly.
Without access to the Internet, Outlook won't be able to download meeting data from an Exchange or IMAP account.
Once you've verified that your Internet connection is functioning properly, check that your account settings are properly configured.
If the nickname cache is corrupted, Outlook may be unable to identify recipients, may offer incorrect recipients when automatically completing the email address, or may send the message to the wrong person.You can use the stock calendar, S-Planner on Samsung phones, HTC Calendar on HTC, or Google Calendar's official app to test this.If they work and Digi Cal don't - please send us an email with the details. Check the sync status of the phone and account, they must be all enabled to allow syncing.For Google Calendar: If you're running on a device with Android 4.0 or higher, please install the official Google Calendar app.Other than installing a new interface, this "app" also contains a new version of the calendar synchronization adapter for talking with the Google Calendar servers.
