calendar not synching past certain date

Calendar
1

Hi … one of my calendars isn’t synching (properly) … anyone have a some good advice?

Setup:

  • eM Client 10.3.1738 (984d31d) on an older Win10 machine
  • several accounts (email / calendar / …)
  • same setup on two other PCs (one Win10, one Win 11 … neither has this problem)
  • difference here: not used in 4 weeks & on a cell phone hotspot (which can however pull 10-20Mbps)
  • (OS is updated, no browser open to limit bandwidth)
  • the calendar in question is a google calendar

Behavior:

  • yesterday (6/18/25) I started eM Client on the machine … as usual, all synchs were performed
  • … but main calendar was suspiciously empty (expect other entries (other calendars like iCloud, other google calendars, Web Calendars, …) - despite the synch arrows still spinning
  • checked operations - sure enough the calendar in question was still synching (yellow bar filling) … and MailClient.exe ist pulling a “steady” ~13,000 - 20,000 B/sec through the hotspot

I tried …:

  • restarting eM Client (yesterday)
  • moving the hotspot around to improve bandwidth
  • updating OS, running a virus scan, restarting the PC
  • turning off antivirus (I have no VPN installed)
  • letting the whole thing run over night (12+ hours - hopefully I haven’t exhausted my data budget)

Result / addtl. observation:

  • nothing changes (still keeps spinning, pulling data, …)
  • no errors are being displayed in operations

Also tried …:

  • going “back in time” through the calendar, I realized that the events are being populated … but only through October 15th 2024 … then the process stops, the yellow synch bar (in operations) goes blank again … and ~30 sec later, the process start over
  • “repairing” the calendar (forced synch) … same behavior persist

… anyone any idea what’s going on here - and how I can fix this? (kind of need my calendar back asap … :worried:)

Thanks.

one of my calendars isn’t synching (properly) … anyone have a some good advice?

eM Client 10.3.1738 (984d31d) on an older Win10 machine
several accounts (email / calendar / …)
same setup on two other PCs (one Win10, one Win 11 … neither has this problem)
difference here: not used in 4 weeks & on a cell phone hotspot (which can however pull 10-20Mbps).

If you have a 10-20mbps connection then it’s nothing to do with that.

If your other Win 11 PC’s with the same accounts setup do sync the same calendars ok and your Win 10 PC has no optionally installed firewall/security programs or antivirus program or VPN enabled “and is not getting any email or calendar data”, then could be your Windows 10 “cannot reach the License Server” so has deactivated and is not getting any data.

See extract from @Gary post below from the following thread.

https://forum.emclient.com/t/licenseserver-cant-be-reached-since-last-10-days/80922/4

"eM Client needs to periodically contact the license server to validate your license. If you have a firewall or VPN that is blocking the connection, then eM Client will eventually be disabled.

“Can you see if these links open in your web browser”:

https://licensing.emclient.com
https://licensemanager.emclient.com
http://emclient.com

“No need to login on the pages, just open them”

Now “if you can reach the License servers ok” with you Windows 10 machine and eM Client is showing activated ok via “Menu / Help / License” then could be you might possibly have a eg: corrupted account in eM Client and might then either need repairing or removing and readding.

So if it’s IMAP, Exchange, Office 365 or iCloud calendar, try “right clicking on the word Calendar” directly under your account, and then click “Properties” at the bottom. Then click the “Repair” tab at the top and click “Repair”. That will clear your local calendar cache in eM Client and resync your online calendar events locally.

Now if Repairing your calendar doesn’t make any difference, then go to “Menu / Accounts” and remove and readd your account via the automatic account wizard or manual option depending on your specific account setup and then save accounts and close and reopen eM Client and see if that updates your events.

Lastly if none of that makes any difference then “if you originally installed eM Client from the eM Client website”, then go to the release history page and try updating to the latest version 10.3.2412 just released recently and see if that fixes your calendar problem.

Note: Before repairing or removing and readding your account or before updating to the latest version, “make a manual backup first” via “Menu/Backup” incase you need to restore for any reason. You can see when the backup is complete in Show Operations via clicking the drop-down on the right of Refresh top left.

Thank you @cyberzork - I will check on the licensing aspect over the WE when I’m back at the cabin where the PC is located … somehow I have a hunch, that might not be the problem, though, as all other calendars, emails, etc. sync just fine (and I haven’t gotten a “can’t reach the License server” message - which I have seen in the past when turning the hotspot on AFTER I opened eM Client).

As mentioned, the calendar in question is a google calendar and I did try to “repair” the calendar without success.

… yes, that would have been a good idea … :man_facepalming:

… I had the feeling it might come to this - hopefully that’ll work w/o complications. (The fact that it seams to sync years of events on the calendar only to then stop at a date 8 months ago seems to indicate a corruption of sorts on an event on that particular day, doesn’t it?)

… good to know - I went ahead and downloaded the install file and will take it with me to try that out as well.

Well @cyberzork … I checked the license - it’s active … I tried to open the three webpages as @Gary suggests in his post (all pages open w/o a problem).

I updated to Version 10.3.2412 (260ec1e) and removed the google calendar in question - closed eM Client, reopened it & added the calendar back to accounts.

The same behavior persists:

Week by week the calendar populates, but the last (newest) event appearing is on 10/15/2024 (12-12:45 pm) … then the process stops, nothing happens for ~30 sec, then all events disappear and the whole thing starts over - it’s stuck in a loop (with no errors being produced in operations). (sidenote: I can’t be certain, but I also believe only about 4 years leading up to the halt appear to be populating … but that’s not as important as not going past 10/15/24)

All other calendars, emails, etc. - even tasks from the same calendar are not affected … nor does this behavior appear on either the other Win 10 PC or the Win 11 laptop.

I am a bit stumped - I really thought, removing & adding the calendar surely would fix this … :thinking:

I have now also turned on “logs” for the calendar (settings/advanced), but the now over 300MB large txt file appears too big for me to open (notepad remains unresponsive for a long time)…so I am not really sure what’s going on and/or what to try next …!? :worried:

Correction: The log file finally opened - but boy, notepad is not equipped to handle such a large file … assuming I can get it to cooperate, anything specific I should be looking for?

I updated to Version 10.3.2412 (260ec1e) and removed the google calendar in question - closed eM Client, reopened it & added the calendar back to accounts.

The same behavior persists.

As repairing your calendar didn’t help, and removing and readding the calendar didn’t help, and updating to the latest version also didn’t help, and eM Client appears to be able to reach the License servers and is activated, then I can only next suggest to contact VIP support and lodge a support ticket for further assistance if you have a current active paid Pro or Personal version.

I suspect they will get you to do eg: Gmail IMAP logging to determine why it’s not synching and attach that with your support ticket.

on a hunch I did a search for “2024-10-15” in the log file, and pretty much every entry has
“created”: “2024-10-15T19:25:16.000Z”,
“updated”: “2024-10-15T19:25:16.405Z”,
(w minor changes in times) in it.

I am starting to believe that date has another relevance, as I switched from Outlook to eM Client right around that time and did a major calendar dump from my then exchange account to my google calendar … that may be part of it. But that still doesn’t explain why this behavior exists …

okay, I’ll give that a try - thank you for the suggestion @cyberzork … :+1:
