Moves Events / Ignores Events

[AlKing47]

Events created in Outlook are moved, both times and days. Events created in Google are sometimes ignored. Both issues are sporadic, and just recently started.

Please could you apply #2047 hotfix to see if that helps? Note, if you have items synced with the wrong start time, you will need to run a one-way full sync from the calendar that has the correct time (should be Outlook) to fix Google up.

I'd need more detail on the "sometimes ignored" Google created items - what date are the on, single instance/recurring etc. Given you are only syncing a day in the past, if they are created eg two days in the past, then #2047 might resolve that too (due to your GMT offset).

I'm still having the same issue with my calendar times/dates getting shifted for some (but not all) events. 2.11.2.1 with hotfix applied.

@Katanasnk Which items? Which calendar? Which time zones? Syncing in which direction? For new or existing items? Can you provide log file evidence and screenshot of affected item in Outlook and Google including their time zone information?

Unfortunately I uninstalled this morning so my log files are gone. All my calendars are set to EST (GMT-5). I had a bidirectional sync, and times were disrupted (but matching!) on both calendars, frequently shifted by 5 hours. This affected both new and existing items, but apparently only ones created after about Jan 14. It was also a progressive issue; that is, it would shift a time and then shift it again and again. I had calendar entries that were 15 hours off the originally scheduled time.
I'm sorry-I know this doesn't help much in terms of troubleshooting. I just couldn't keep having to manually fix my calendar.

I have a bit similar observations, but I am not sure if it is related. I also noted this just recently (last few days), where some events have been shifted -1h in one of the calendars (but not all events). Furthermore, it started to generate duplicates for many events (mostly for recurrent events, but also a few single events, but different number of duplicates for different events). I tried to look for patterns but I see none, so I do not know where to start searching to make it reproducible.
