'OtherMails' is an attribute managed by Azure AD afaik, you cannot change it via the Exchange cmdlets. You should be able to change it via Set-MsolUser/Set-AzureADUser or the Graph API directly, but I'm not sure if such changes later flow to ExO. They should I suppose, so give it a try.

I set it on Azure AD side and now when I run Get-AzureADUser I get Provisioning Error:

I tried to wait for synchronization (2 days) but the provisioning error still occurs.

Could you advise something? Should I wait longer for synchronization?

As the error message suggests, you seem to have another object to which this address is already assigned, which probably explains the initial "empty" value. Try to locate said object by running

Get-Recipient email@domain.com

Or open a support case.
