How to synchronize Bitrix calendars with Exchange?

Question

1C-Bitrix

Good afternoon! I'm trying to synchronize the Bitrix and Exchange calendar through the DAV
module . Please tell me how to grant rights to a user in AD to view all employee calendars in Exchange? At the moment, synchronization works only if you log in to the account (whose calendars need to be synchronized) via OWA / Outlook and grant full access (by sending an invitation by mail) to the calendar to a user who is connected to the DAV module in Bitrix. With 250+ accounts, this is at least a problem =)

Answer 1

There are two options,
1. powershell - get a list of all mailboxes, get-mailbox -result unlimited, set-mailboxfolderpermission $_.identinty:\calendar (a little more complicated, but this is not freelancing) - give editor / viewonly rights for one user.
2. impersonate account - much more complicated at first glance, but also quite affordable, the solution is once and for all, but you need to understand the security risk when owning credits to this account.

Answer 2

Via Powershell with the Exchange module

hendrixix , can you describe how you achieved this:

Those. what rights did you give to the user in Exchange, so that in general the exchange works under him, for example, so that he can at least take the events of his calendar from Exchange? The problem I have now is that when I try to collect data under the service user of this service user (namely, the calendar, nothing else is needed), an error 403 is generated:
