OGCS Version: v2.10.0.0
Edition: Installed / Portable
Sync Direction: O<->G

Bug Description
At Google Calendar, strange strings such as 040000008200E00074C5B7101A82E00800000000902F05A11585DA010000000000000000100000002A9C8797659215499157664B8762996B are populated. Please check attached screenshots. These strings are not entered at my Outlook calendar and I create schedules at Outlook and sync bidirectionally(O <=> G).

The 2.10.0 beta was released almost a year ago, and I think you were using that version of OGCS without issue before this started to happen? Have you always synced the description attribute when syncing?

That string being added to your Google description looks like the Outlook Global ID value - it's not something that OGCS ever puts in the description, so I think some other change or software has done this. If you create a brand new Outlook item with an empty body/description, what does OGCS sync to Google - does it still contains that string?

[mrdantzig]

Thanks Paul for your reply.I've upgraded OGCS to the latest alpha version but the problem is not resolved. I've reinstalled outlook and it didn't work either.I don't use any other Google sync program.Let me try to 'create a brand new Outlook item with an empty body/description and sync to Google' next week and get back to you with the result.All the bestsStephen

I've upgraded OGCS to the latest alpha version but the problem is not resolved.

I wouldn't expect it to be, as I don't believe this is directly due to OGCS - the same version 10.2.0 can't suddenly start exhibiting new behaviour if you haven't changed its configuration at all...

You'll need to do some testing to narrow down the behaviour and hopefully the cause, eg:

• Uncheck sync of Description by OGCS in settings
• Create a new Outlook appointment with no description
• Sync O->G, confirm the description in Google is empty
• Add a description in Outlook, resync, confirm Google description is still empty

• Check sync of Description by OGCS in settings
• Create a new Outlook appointment with no description
• Sync O->G, confirm the description in Google is empty
• Add a description in Outlook, resync, confirm Google description matches

• Turn logging level up to ULTRA-FINE - this will log the values of the calendar attributes.
• Edit one of the Outlook test items
• Sync and check the logs to see what is has for

Thanks Paul Please check the attached OGCS sync log file with corresponding screenshots. AT O => G mode, it seems the description at Google is not changed. Best Regards, Stephen 2024년 4월 28일 (일) 오전 2:31, Paul Woolcock ***@***.***>님이 작성:

For me to troubleshoot this:

1. Please refrain from replying my email - attachments are not possible
2. Apply the hotfix on Cannot determine Outlook appointment body format #1844 to resolve the "The length of the string cannot be zero" error
3. Repeat the tests and login to GitHub to upload log file etc.

From the limited evidence I can see from the emails, it looks like the description is only being updated with the string from Google into Outlook. This isn't what you originally reported and not any of the tests I asked you to carried out.

If you can't reproduce the problem with the tests I asked, the problem does not originate from OGCS.

Another test would be:

1. For an item that has the correct Outlook description, but incorrect Google description
2. Open the Outlook item and edit it somehow (eg add a space to the Location field); Save and Close
3. Sync to Google; confirm Google was updated
4. Confirm the Google description is now correct and matches Outlook.

When updating this ticket, please make it clear what test you have performed and the outcome.

Your logfile doesn't seem to capture the entire sync - maybe it was spread across multiple files?

You only seem to have run the last test in my previous comment, where you've turned on ULTRA-FINE logging and edited the item.

This has shown however that some items are having their Body reported correctly from Outlook and others are apparently not. You'll need to work out how to reproduce the problem on-demand - ie what are the steps to create an Outlook appointment which syncs incorrectly to Google. That what my earlier test steps where prompting you to do.

• Are you able to reproduce this issue on a different machine?
• Please could you uncheck "Word Obfuscation" - you don't seem to have any rules defined anyway, so there's no value in checking it and would be helpful to rule this out.
• Why do your Google screenshots show the time in the location field? eg 9:30~ 10:30 - I don't know where this is coming from either.

Hi Paul

I'm attaching most of the recent log files.
Here are my answers to your 3 comments:

Are you able to reproduce this issue on a different machine? => I only use OGCS at one PC at my office.
Please could you uncheck "Word Obfuscation" - you don't seem to have any rules defined anyway, so there's no value in checking it and would be helpful to rule this out. => Unchecked it. Let me check if there are any changes when I sync again.
Why do your Google screenshots show the time in the location field? eg 9:30~ 10:30 - I don't know where this is coming from either. => There's nothing at the location field of the above screenshot. It's at time field. Please find the attached screenshot.

Thanks

I've tested with 2 schedules, 1 recurring and 1 non-recurring, again by simply adding "(???)" to Outlook descriptions.
The description at Recurring schedule was removed at Google while the description of non-recurring changed to "04000..." string.
I've set 'word obf..' off and sync direction was set to 'O => G".
Please check the attached log file and screenshots.

Thanks - sorry, rather confusing in a language I have zero ability to read I'm afraid 🙂

outlook_appointments.csv
google_events.csv
In case these file give you any clue.

This is actually super useful - the outlook_appointments file shows that none of the descriptions have any of these strings in them, only the GlobalID field for which I would expect. And the GlobalID for Cha 이주호 does indeed match the description you are seeing in Google. However, Cha 이주호 actually has no description at all in Outlook, but this doesn't match with your screenshot?? Also your zipped log files don't cover the tests you carried out - last log is at 09:59 on 2-May, but your tests were done at midday? Can you provide those logs?

Hi Paul,

Uploading 2 new screenshots and log files created today. As you can see the highlighted status at the screenshots, Outlook descriptions are changed to the strings "04000000..." when synchronizing Outlook calendar to Google calendar.

All the bests,
Stephen

[phw198]

This is the log for the first highlighted changes - it shows the same description as per your screenshot. But you didn't provide the outlook_appointments.csv so I don't know what that was reporting for the Description field. Please provide all of the evidence from the same point in time when you see this issue happen.
