Shared Mailboxes or Calendars not updating since mid Jan 2022 unless disable Shared Mailbox Caching
Hello. We're an MSP and since around 17th/18th Jan we've had one or two users in 7 different companies (tenants) report issues with shared mailboxes or shared calendars they have access to not upda...
gblackburn Something that worked for me:
As others have done, disable caching shared mailboxes AND disable the "shared calendar improvements" option. Restart Outlook, then enable only the caching of shared mailboxes, because clearly the "shared calendar improvements" aren't.

Best of luck
