If you are not seeing the CityGrows email notifications you'd expect to receive, and your organization uses Microsoft Exchange, the issue may be related to a known issue with how Microsoft Exchange "quarantines" emails send by our email distribution provider (Sendgrid). Here's what to look for and how to fix the problem:
1. Search for CityGrows messages that are stuck in quarantine
Sign in to Office 365 and go to the Security and Compliance Center using the email account.
On the left, expand Threat Management, choose Review, and then choose Quarantine. Tip: To go directly to the Quarantine page in the Security & Compliance Center, use this URL: > https://protection.office.com/?hash=/quarantine
Search for "CityGrows" to see if there are messages from us stuck in Quarantine.
2. Release quarantined messages and mark CityGrows messages as "not spam"
Release any quarantined messages from CityGrows so that the message is sent to your mailbox (and so that future messages will be visible).
Report the message to Microsoft for analysis as "not spam" or a false positive.
By default, the Security & Compliance Center displays all email messages that have been quarantined as spam. The messages are sorted from newest to oldest based on the Date the message was received. Sender, Subject, and the expiration date (under Expires ) are also displayed for each message. You can sort on a field by clicking the corresponding column header; click a column header a second time to reverse the sort order.
You can view a list of all quarantined messages, or you can search for specific messages by filtering. You can only do bulk operations on up to 100 items, so filtering can also help reduce your result set if you have more than that. You can quickly filter messages for a single quarantine reason by choosing an option from the drop-down list. Options include:
Mail identified as spam. These quarantined messages are shown by default.
Mail identified as bulk mail.
After you find a specific quarantined message, click the message to view details about it, and take actions. You can release the message to your mailbox, preview the message, download the message, or delete the message from quarantine immediately.
You must have admin permissions in Office 365 to work with quarantined messages that were sent to other users.
