Outlook asks to save when closing appointments without any change

Dear Fnurk,

Thank you for your reply.
I'm doing more research and testing on this issue, but since the reasons can be varied, please try more things:

a.
Please navigate to File > Options > Mail > Save messagesto disable “Automatically save items that have not been sent after this many minutes” feature on the Outlook client. If this feature is enabled, try disabling it and see if the problem persists.

b.
the issue might be caused by corrupted add-in in Outlook, it is recommended you run Outlook on safe mode.

1. Exit Outlook client.
2. Right-click Start button to Run.
3. Type "Outlook /safe" on the Run box and press Enter.

(Note: there is the space but not quotation marks in the command)
Open Outlook in safe mode - Microsoft Support

c.
Clear cache files in Outlook. Before we start the liquidation process, please save your work in Outlook and close Outlook.

1. Press the Windows key (the key with the Windows logo) and the R key at the same time. The Run dialog box pops up.
2. Type or paste %localappdata%MicrosoftOutlook in the Open box and click the OK button.
3. Locate the Roaming Cache folder and double-click it to view the cache files.
4. Press Ctrl + A to select all cache files, then right-click and click the Delete button in the menu.

you can also try to clear the cache in Skype for Business, for the detailed steps, please follow below:

1. Log out of Skype for Business.
2. Delete any sign-in information.
3. Exit Skype for Business.
4. In File Explorer, navigate to "%localappdata%\Microsoft\Office\16.0\Lync".
5. Delete the sip_profileName folder.
6. Delete all files in Tracing folder but do not delete the folder itself.
7. Open the command prompt and run "ipconfig /flushdns".

Hope this information is useful to you. If there is any progress on the issue, please update it with this post and we will do our best to help you.

Thank you for your patience and cooperation, I wish you all the best!

A: outlook indeed required an update, but also after the update problem is still there

B: downloaded SARA and however if you select problem with calendar you only can select three things not related to this issue... i tried all of them but none succeeded in a repair of the issue

C: run the steps, the calcheckerr report showed some meetings which contained errors (duplicate ones, or one with many appendices) tried to delete those and restarted outlook but also that did not result in any improvement

any other suggestions?

Dear Fnurk,

Thank you for your reply.

The factors that contribute to this issue are diverse, so kindly ask you to try more things:

a.
If the version of Outlook client is not latest, please also try to update it to be latest for better using experience, you can update it in File > Office Account > Update Options > Update Now.

b.
It is recommended to diagnose calendar in Outlook via Support and recovery Assistant(SaRA) tool for Office 365.
Scan by using Microsoft Support and Recovery Assistant - Outlook | Microsoft Learn
For detailed steps, please follow below: 1. Download SaRA in https://testconnectivity.microsoft.com/.

2. Select Outlook > I'm having problems with my calendar.

c.
It is recommended you try the following tool for further troubleshooting. 1. Download CalCheck and extract the .zip folder. (**Note:**If Outlook client is 32-bit, CalCheck tool needs to be 32 bit)

2. Run Command Prompt.
3. Paste "cd [Path of CalCheck tool folder]" and press Enter, for detailed information, please follow the screenshot below:

4. Paste "CalCheck -F -R -V" and press Enter.

5. Delete all files in CalCheck folder, and delete the folder itself.
6. Restart Outlook client.

If the issue persists, please update, we will try our best to assist. Your cooperation is appreciated.

Same problem for me; and all the proposed solutions do not work. The display resolution/scaling is not applicable since the problem also occurs with a single laptop display.

see my feedback for each suggestion, none unfortunately did resolve theissue

1A not applicable, for web client, thats a totally different interface and there is no "x" to close it (you have to select delete or save)

1B safe mode issue still persist as already mentioned in my post

1C new profile also did not solve it

2. Tried this before and set it both to 100% but issue still persists
3. not applicable, its for every meeting even withouth links or any body test... just opening it and closing it won't show the message, however locking your machine in between will trigger the pop up
4. tried this before but did not solve the issue

any other suggestions or diagnostics steps i can undetake? my outlook version is updated in my original post

and by the way: i've tried this on my colleagues outlook as well, and the same issue over there... so its not related to my PC only...
