Work and school accounts

Some organisations only let you use apps their IT department has approved. Then 1B Calendar says Your organisation must approve 1B Calendar first. Send this link to your IT administrator.

Click Copy the link for your administrator and send it to them. Once they approve it, sign in again.

Repeating events in Microsoft 365

In Microsoft 365 accounts, changing a whole series (All events) changes its title, place, notes and reminder for now. To change the times or the repeat rule of the whole series, use Outlook; single days can be changed in 1B Calendar.

Problems and solutions

“Not available in this build yet.”

Signing in with Microsoft needs Microsoft's approval of 1B Calendar. If you see this message, it will arrive in an update.

“The browser took too long.”

Try again and finish signing in in the tab that opens.

“Signed in, but there are no event calendars in that account.”

The account you signed in with has no calendar (some work accounts only have email). Check that it's the right account.
