No events are syncing

On this page

If you were able to successfully
  1. connect your calendars; and
  2. create a sync connection
but it appears that nothing is happening, here are some things to check:

Check your calendars in a browser (rather than an app)

In case you are having local sync issues on your device, check you calendars in a browser. For Google calendars, that means logging into calendar.google.com in a browser. For Microsoft work or school calendars, log into outlook.office.com in a browser. For Microsoft personal accounts, log into outlook.live.com If you see synced events in the browser and not your device, then you will need to troubleshoot your device (this is not something CalendarBridge has any impact on or control of).

Make sure to look at dates in the future

CalendarBridge does not sync events that were in the past at the time of sync creation (except for recurring events that also extend into the future).

Check that you picked the correct calendars

Each of your accounts likely has more than one calendar, so double check you selected the correct source calendar (where events will sync from) and the correct destination calendar (where events will sync to). For example, this user has 6 calendars on her account: The first calendar is the primary calendar on the account (this is indicated by “Primary Calendar” in the third line of text.  On a Microsoft account, the primary calendar will always be named “Calendar.” The second and third calendars are “Read only” which means they can be used as a source calendar, but not as a destination calendar. The last three calendars are “sub calendars” or “secondary calendars” that the user has created on this account.

Remember that sync connections are one-way and we don’t sync edits to event copies

If you want events to sync from calendar A to calendar B and from calendar B to calendar A, you will need two sync connections. Also, remember, we do not sync edits to event copies — event copies that we create should be treated as read-only.

Make sure you have completed setup of your Microsoft 365 mailbox

If your Microsoft 365 email address is brand new, you must login to it to complete setup of your calendar. A sign that setup has NOT been completed is that the account does not have “Birthdays” and “Holidays” calendars (which are created upon first login).

Check your Microsoft 365 plan type

If your calendar is Microsoft 365, it must be on a plan that includes Exchange Online.  Microsoft 365 Family and Personal plans do not include Exchange Online and do not support CalendarBridge. If you have connected a Microsoft 365 account that does not include Exchange Online, the calendar that shows up on outlook.office.com does not match the calendar you see in your Outlook app.  Rather, the calendar you see in the installed version of Outlook will say “(this computer only)”:
Outlook calendar this computer only
CalendarBridge cannot access calendars that exist on “This computer only.” To sync those calendars you will need software that installs and runs locally on your computer. One free one is CalDav Synchronizer (which CalendarBridge is not affiliated with in any way).

Confirm you have connected the right Microsoft account

Microsoft allows you to have separate “personal” and “work or school” accounts under the same email address — and many people accidentally create a “personal” Microsoft account under their work email address without even realizing it. One way to tell if you have two Microsoft accounts is you may see something like this when logging into Microsoft: User has two microsoft accounts If you are intending to add a Microsoft account setup by your work or school, make sure that you are selecting a “work or school” account during the login with Microsoft process. On the enter password screen, a login.live.com URL means you are logging into a personal account, whereas a login.microsoftonline.com URL means you are logging into a work or school account.

If none of the above seem to be the reason your sync connection is not working, please submit a support request.
